Pressure Sustaining Valves

Pressure Sustaining Valves

Pressure Sustaining Valves (PSV) sense the upstream pressure and compare it to the setpoint to determine the valve position in order to maintain a set pressure upstream. As the upstream pressure rises the valve starts to open allowing flow downstream and if it falls below the setpoint the valve will shut. The use of these valves enables the prevention of pressure starvation to upstream processes in the event of a major consumption downstream. They can also be used to balance pressures in a ring circuit.
Filters for Compressed Air, Gas & Liquids

Filters for Compressed Air, Gas & Liquids

Filters protect pressure regulators and other valves from damage or reduced efficiency due to a build up of particle or liquid contaminants. Compressed air and gas pipes can convey rust scale, dirt and other particles from elsewhere in the systems and filter stages remove these from the gas, especially where the gas may then come into contact with product that must not be contaminated. Compressed air systems also require the removal of water from the air stream and this must be periodically bled from the filter bowl. Coalescent Filters are used as a second stage to remove finer contaminants down to 0.01 microns and must be protected by a coarser pre-filter to prevent premature failure.
Water Hammer Arrestors

Water Hammer Arrestors

Pressurised diaphragms (Water Hammer Arrestors) absorb the water hammer pressure transients, reducing or eliminating the noise, vibration and damage caused by water hammer. For best effectiveness, these devices need to be fitted at the optimum point in your system to get the most benefit. Call us to discuss where this will be for your system.

Two Way Solenoid Valves

Two Way Solenoid Valves

Measure Monitor Control has a large selection of 2-way solenoid valves. They have two ports (inlet and outlet) and two switching planes (open or closed) and are electromechanically actuated. They are used to start/stop the flow of gas/liquid and are most commonly normally closed, so that if power fails the valve will close.

2-way solenoid valves are suitable for a wide range of applications, including: isolation / shut off, release, distribution, dosing and mixing.
Three / Two Way Solenoid Valves

Three / Two Way Solenoid Valves

What does 3 way mean?

3 Way or 3 port solenoid valves refer to the line connections in that there are 3 ports which makes them ideal for diverting flow from one path to another. Unlike 2 way valves that are intended for isolation purposes, 3 way valves are used for directional control and have 3 function variants − normally closed (NC), normally open (NO) and universal (U).

3 way solenoid valves are used with liquid or gaseous media and can incorporate a huge variety of options:

Environmental − IP65, IP67, ATEX, IECEx, …

Functional − manual override, manual reset…

In addition to material options for the valve body and elastomers for compatibility with a wide range of gases and liquids.
Five Way Solenoid Valves

Five Way Solenoid Valves

5/2 solenoid valves and 5/3 solenoid valves are most often used as directional control valves for double-acting pneumatic actuators. The single-coil type of 5/2 valve usually has a spring or pilot air return so that when de-energised, the valve returns to it's starting function. Dual coil valves do not have this return facility and require the second coil to be energised to return the valve to the start position. 5/3 valves have 2 coils and if neither is energised, the default state it returns to in the centre position can either be all ports blocked, all ports open or pressure applied in that the inlet pressure is connected to both outlet ports. Manual reset valves require operator intervention in order for the valve to maintain the energised position.
Two Way Air Pilot Operated Valves

Two Way Air Pilot Operated Valves

What is pilot operated?

Pilot operation is the main force required to open the valve is provided by the media pressure. The pilot can be very small as it only controls the flow of a small diameter impulse line that allows the fluid to open the main diaphragm or piston.

What does 2 way mean?

2 Way or 2 port air operated valves refer to the line connections in that there is a single inlet and outlet which makes them ideal for flow isolation. For most of these valves, the flow direction through the valve must be from the inlet to the outlet as reverse flow will cause the valves to fail or operate unreliably.

Depending on the model, 2 way pilot operated valves are used with liquid or gaseous media and can incorporate many varieties of options:
Functional − normally open or normally closed

Feedback − limit switches, visual position indicators

Various elastomers for compatibility with a wide range of gases and liquids
LK Series Lock-Up Valves

LK Series Lock-Up Valves

A lock up valve works by sensing the drop in pressure at the signal port. Once this pressure is lower than the adjusted spring compression, the valve closes the control ports, isolating the downstream circuit. The Sitecna LK pneumatic lock up valve range combines extreme sensitivity to changing pressure, single or dual circuit operation and comprehensive certification to deliver optimum performance in harsh conditions. Precision manufactured from 316L stainless steel or copper free aluminium, the LK lock up valve range is ideal for use in valve actuation systems and pneumatic automation where pressure control and redundancy are crucial.

Measurement - Dew Point

Measurement - Dew Point

What is Dew Point?

The Dew Point is the lowest temperature that allows water vapour to remain in a gas without condensing to a liquid state. As the air or gas temperature drops, its ability to absorb water vapour drops until it becomes completely saturated and below this dew point temperature, water droplets will start to form.

In pressurised systems such as compressed air distribution networks, the dew point is directly related to the temperature AND system pressure. As pressure increases, the dew point temperature also rises meaning that the potential for vapour to condense out occurs at a higher temperature. In practice this can mean that instead of the condensing temperature being quite low, the dew point could be at or above ambient temperature.
Measurement - Leak Detection

Measurement - Leak Detection

Detecting compressed air or gas leaks is a vital part of maintenance planning due to the cost savings that can be made when the leaks are repaired. Deciding which leak detection method to employ can be complex and we can help you to understand the choices available so that you make the best decision for your company.

Measuring leakage can sometimes be confused with detecting leakage but although the two are complementary, don't be confused with claims of devices that can tell you how much a leak is costing. There is only one accurate way of measuring leakage and we can help with that too. Contact us today to discuss the options available.
Ultrasonic Flow Measurement

Ultrasonic Flow Measurement

Ultrasonic flow meters utilise two high frequency transducers to bounce signals across a pipe to the other sensor. By measuring the transit time which is proportional to velocity, the flow rate can be calculated automatically based on the known medium properties and pipe dimensions. Most often used on water, ultrasonic flow meters may be suitable for other liquids. Please contact us to discuss your requirements.
Compressed Air Purity Measurement

Compressed Air Purity Measurement

Measurement of compressed air purity is vital for ensuring compliance with plant operating standards and ensuring optimal conditions for your processes. Keeping the compressed air or gas to a particular ISO 8573 purity standard can also help with plant reliability and regular monitoring can provide advanced notice of issues that may need to be addressed by maintenance or overhaul tasks.

Compressed air for breathing regulators falls under the EN 12021 standard and requires not only contaminants to be measured but also gases to ensure that the air is safe to breathe. Breathing air testers allow the user to monitor Oxygen (O2), Carbon Monoxide (CO) and Carbon Dioxide (CO2) with dew point/humidity and oil or VOC contents.
Thermal Mass Flow Measurement

Thermal Mass Flow Measurement

Thermal Mass Flow Meters use a calorimetric principle to directly measure the mass flow of the particular gas independent of the working pressure and temperature. They are suited to most common dry gases such as compressed air, nitrogen, carbon dioxide, oxygen, argon, helium, hydrogen and methane. The flow sensors can output the instantaneous flow rate, total consumption and temperature of the gas depending on the communication method employed and the S401 and S450 series sensors can be combined with the S409 flow switch to enable separate measurement of flow and consumption in bidirectional systems. S415 is intended as an economical flow meter for air or nitrogen only. S418 is more accurate, suitable for a wider range of gases and includes an integral datalogger.
Oil Measurement in Compressed Air

Oil Measurement in Compressed Air

What does ISO 8573 actually say about oil measurement?

ISO 8573-1 states that the total oil liquid, aerosol and vapour concentration figures must be combined to attribute a purity class but if you need to achieve class 1 or 2, how can this be achieved?

ISO 8573-2 gives two ways of measuring aerosols but only one that is also suitable for liquid oil − Method A. This requires the use of ISO 12500-1 class coalescent filters in series to collect oil from the airstream during the test period and the volume collected is measured to calculate the concentration in mg/m³.

ISO 8573-5 covers the sampling of oil vapour and subsequent analysis by gas chromatography to determine the vapour concentration.

The results of these two methods then need to be added together and compared with the purity class table in ISO 8573-1 to determine the actual purity class achieved.
S531 Advanced Ultrasonic Leak Detector

S531 Advanced Ultrasonic Leak Detector

The S531 ultrasonic leak detector offers an efficient and cost effective means of identifying gas leaks much faster than the traditional and messy soap bubble method and is capable of indicating both leakage flow and cost.

The S531 leak detector can collate additional contextual data such as voice recordings and photographs with the integral camera that show the exact leak location for inclusion in a leak survey report. When the user inputs the sensing distance for each leak and the site air generation cost per unit, the S531 will also display and record the leak flow rate and cost for every location.

S531 ultrasonic leak detector is compatible with the SUTO Leak Management System software (LMS below) and data can be downloaded through Bluetooth or USB when compiling reports.
How to Measure Compressor Efficiency and FAD

How to Measure Compressor Efficiency and FAD

How important is Compressor Efficiency?

The distribution of compressed air in industrial plants is prone to efficiency losses through pressure drops and leakage but the largest inefficiency is at the point of generation. Compressor units are most commonly run with electrical induction motors driving piston or screw compressors. Depending on the scale of the installation, the electrical consumption of these compressor plants can be a significant part of the overall plant electric bill as they are always responding to system demands to maintain pressure. The mechanical compression process is very inefficient with over 90% of the electrical energy lost as heat and noise. Cooling or heat reclamation systems can have an influence on the overall efficiency but it is still very costly to produce compressed air.
Compressed Air Leak Detection

Compressed Air Leak Detection

What is Leakage?

In regards to compressed air and gases, leakage refers to unintentional venting of the gas to atmosphere. Leaks can arise from corrosion, vibration or material failure and most commonly at joints or component junctions in the pneumatic circuit. Note that leakage is normally considered separate to the venting of compressed air through the action of valves and actuators where the air energy has already been partially used.

Compressed air systems are large users of electricity and can be a significant proportion of the overall plant electricity consumption. It is generally accepted unlikely that perfect sealing can be maintained in pneumatic systems and up to 10% leakage may be deemed acceptable. This sounds like a high percentage but leakage is often much higher than expected with figures up to 40 or 50% not being unusual. This makes maintenance of compression and distribution systems an important part of the plant maintenance scheme.
S430 Pitot Tube Flow Sensor

S430 Pitot Tube Flow Sensor

S430 is an insertion type flow meter using the pitot tube principle, designed for flow and consumption measurement in wet air, high mass flow or high velocity applications. Installation requires a G3/4″ connection and the mounting stem is graduated to simplify centering the sensor tip for pipe sizes up to 10″ diameter (DN250).

S430 has a new 3 line colour display displaying flow, velocity and pressure with bluetooth interface for remote sensor configuration. S 430 offers a choice of communication options including 4-20mA, pulse and SDI (SUTO Digital Interface), Modbus/RTU and MBUS.

Pressure range up to 1.6MPa

Output 4-20mA, SDI, Modbus/RTU, MBUS

Optional colour display

Bluetooth interface

S430 is ideal for measuring at the compressor outlet as the pitot tube design is not damaged by the very wet gas unlike thermal mass flow sensors which cannot be used here. S 430 offers FAD calculation facilities for accurate measurement of compressor performance.
Self-Contained Portable Breathing Air Tester

Self-Contained Portable Breathing Air Tester

The S605 is a self contained portable breathing air analyser that is easy to use, produces a detailed PDF report at the end of the test and complies with all the measurement requirements of EN 12021. At 11kg the unit is easily portable so that it can be used anywhere and since all the sensors are inside the unit and there is only one sampling port, there is no need to connect external devices or use chemical indicator tubes in order to determine the results.

S605 has electrochemical gas sensors for oxygen (O2), carbon dioxide (CO2) and carbon monoxide (CO) in addition to the uniquely capable SUTO dual QCM & polymer dew point sensor, PID VOC sensor and pressure sensor. Combining these with a simple to use touchscreen display that clearly shows the readings in an easy to understand manner and an integral data logger, provides an elegant solution to breathing air testing that does not rely on subjective measurements or user interpretation. The S605 will produce the PDF report at the end of every test and it can easily be downloaded via USB for printing or emailing.

SUTO recommend an annual calibration for this unit and simplify the process by the availability of exchange pre-calibrated sensor modules that are simple for the user to swap and return the old sensors through the supply chain so that they can be recycled at the factory. This removes the need for the instrument to be off-site for a period of time and testing can resume the same day once the modules are exchanged knowing that it will be twelve months till the next time it is required.

Compressed Air Purity Measurement
Ensure compliance with plant operating standards and ensure optimal conditions for your processes by measuring compressed air purity. By maintaining the compressed air or gas purity to ISO 8573 standards, plant reliability can also be improved, and regular monitoring can provide advance notice of problems requiring maintenance or overhaul.

Dew Point Measurement
Dew Point is the lowest temperature at which water vapour does not condense into liquid. Under the dew point temperature, water droplets will form as the temperature of the air or gas drops. As this happens, the ability of the air or gas to absorb water vapour decreases until it becomes completely saturated.
