Coriolis Flow Meters
Coriolis flow meters, often referred to as ‘mass’ flow meters, have gained a significant market share over the past 20 years and are the first choice for many flow applications. During this time, their design has been refined resulting in the evolution of a highly accurate and versatile flowmeter.
Coriolis flow meters are primarily designed to measure mass flow (kg/min, tonnes/hour etc.) with accuracy unaffected by changes in fluid density or flow profile. Offering a typical measurement accuracy in the order of 0.1% of reading over a 20:1 turndown, Coriolis flowmeters are available with MID (Custody Transfer) Approval as well as ATEX Hazardous Area Approvals. With the correct selection of tube material, the flowmeter can also work at elevated temperatures above 200 degrees C.

Electromagnetic Flow Meters
Electromagnetic flow meters have been around for years and are the automatic choice for certain water-based flow applications.
Also known as ‘Mag’ or even ‘Mag Flux’ flow meters, electromagnetic flow meters are manufactured in a wide range of sizes, from 2mm bore to over 3 metres in diameter. Manufacturing cost, and therefore selling prices, don’t drastically increase as the flowmeter size increases, making mag meters extremely cost-effective in the case of large bore installations.

Positive Displacement Flow Meters
A positive displacement flow meter otherwise know as 'PD Meters' measure flow by ‘displacing’ a precise and known volume for each revolution of their internal parts. There are many types of internals such as two or three gear oval gear, nutating disc, rotary piston and sliding vane. Because this style of flow meter displaces a known volume, its accuracy is largely unaffected by changes in the physical properties of the liquid, such as viscosity or density. In volumetric terms, a ‘litre’ is always a ‘litre’ regardless of viscosity or density. A PD flowmeter is extremely accurate, offering linearity of better than 0.1% of reading and repeatability of better than 0.05%.
To ensure high accuracy, the clearances inside the flow meter measuring chamber must be as fine as possible without causing excessive wear. This means that the metered liquids this flow meter can measure must be clean and free from suspended solids. In most cases, it is prudent to install a suitable liquid filter on the inlet side of the meter. Positive Displacement flow meters require no upstream/downstream straight pipe lengths so, if required, a filter can be directly bolted to the inlet port.

Thermal Mass Flow Meters
Thermal mass flow meters are a great choice for gas applications and available at a fraction of the price of Coriolis mass flowmeters.
Where the accuracy offered by Coriolis meters is not required, thermal mass flow meters will usually prove to be a suitable solution.

Turbine Flow Meters
Turbine flow meters are one of the most popular and one of the simplest methods of measuring flow. The turbine meter is most commonly used to measure liquid, which includes chemicals and water, but also measures gas.
Electromagnetic flow meters are more commonly used for water measurement. There are varieties of turbine flow meters that are even ideal to measure the dispense of drink or beer.
A free-spinning magnetic rotor spins as fluid passes and small voltage pulses are generated in a magnetic coil sensor mounted in the wall of the flowmeter body. The rotational speed of the rotor and the frequency of the generated voltage pulses are directly proportional to flow rate. Due to magnetic drag at low velocities, the turndown range of the turbine is usually limited to around 10:1.

Variable Area Flow Meters
The variable area flow meter’s operation is based on the variable area principle: fluid flow raises a float in a tapered tube, increasing the area for passage of the fluid. The greater the flow, the higher the float is raised.
The height of the float is directly proportional to the flowrate. With liquids, the float is raised by a combination of the buoyancy of the liquid and the velocity head of the fluid. With gases, buoyancy is negligible, and the float responds to the velocity head alone.
The float moves up or down in the tube in proportion to the fluid flow rate and the annular area between the float and the tube wall. The float reaches a stable position in the tube when the upward force exerted by the flowing fluid equals the downward gravitational force exerted by the weight of the float.
A change in flowrate upsets this balance of forces. The float then moves up or down, changing the annular area until it again reaches a position where the forces are in equilibrium. To satisfy the force equation, the variable area flow meter float assumes a distinct position for every constant flowrate.

Vortex Flow Meters
A vertical flow restriction, known as a ‘bluff body’ is fitted inside the vortex meter bore and as flow passes by this bluff body vortices are generated alternately on each side, similar to the rippling effect of a flag blowing in the breeze. Sensors within the flowmeter body count the vortices as they are generated. There is a direct relationship between volumetric flow and the number of vortices generated and head-mounted electronics converts the signals received from the sensors to display instantaneous flow rate and totals.
Additive Dosing
By combining Flowquip's high accuracy flowmeters with our dedicated dosing and blending flow computers, blending, dosing and additive injection can be highly accurate. But unlike dosing pumps, the process can be accompanied by high and low flow alarms and a full audit trail.

Energy Metering
The DS500 Intelligent Mobile Chart Recorder for Energy analysis − consumption measurement − leakage calculation at compressed air systems
If we talk about operational costs of compressed air plants we are actually talking about the energy costs as they make up about 70 to 80 % of the total costs of a compressed air plant.
Depending on the size of the plant this means considerable operating costs. Even in smaller plants this may quickly add up to 10,000 to 20,000 € per year. This is an amount which can be considerably reduced − even in the case of well operated and maintained plants.

Rotameters
More precisely, the flowmeter consists of an internally tapered plastic or glass tube with a scale engraved along its length. Inside the tube sits a tapered float. The density of the float must always be greater than the density of the metered medium, be it a liquid or a gas. In most cases the Variable Area, or V/A meter, must be installed vertically and look a little like household mercury thermometer.
In a ‘no flow’ situation the float sits at the base of the tube blocking the inlet port. As flow begins the float will be lifted by the force of the flowing medium. The higher the flow the higher the float is pushed up the inside of the tube. Flow rate can then be read by observing where the top edge of the float meets the graduated scale marked on the outside of the tube.
