This type of flowmeter can even be used for handling slurries or water with significant solids content. They can also be coupled with secondary instrumentation to indicate flow rate and total as well as provide a current and/or pulse output.Įlectromagnetic Flowmeters: Are the perfect choice where the metered water contains suspended particles which would prevent other water meters with rotating internals from operating satisfactorily. Turbines don’t have the rangeability of mechanical water flowmeters, usually operating over a 10: turndown, but offer far higher accuracies in the region of 0.2 to 0.5%. Turbine Flowmeters: Can be used in cases of higher working pressures up to 30000 psig, where higher accuracy is required, or hygienic approval is mandatory. Maximum pressure rating is 16 barg with cold water meters rated to 30/50 deg☌ and hot water to 90/130 deg☌. Water meters 2” and below have BSP union process connections whilst the larger bore sizes have flanged connections. Whilst usually just offered with a mechanical non-reset totaliser it is also possible to supply with a low speed pulse transmitter for remote totalising purposes. Versions are available for cold and hot water. Smaller water meters are manufactured in brass and the larger in epoxy coated cast iron. Usually used where high accuracy is not required and price is a significant issue. Mechanical Water Submeters: Available from ¼” up to 6” bore to handle flow rates from a few litres per hour up to 600 m3/hr. V/A flowmeters are available for flows as low as 1 cc/min up to 1000 l/min with accuracy 2-3 percent at best. Care must be taken with regard to not exceeding working pressure and temperature limits … particularly in the case of plastic tube units. Probably the least expensive and least accurate of all water flow meters but eminently suitable where a visual indication of flow is all that is required.

Variable Area Flowmeters: A simple ‘float in a tube’. Often the application will limit the choice of water flow sensor required working pressure, temperature, flow range, required accuracy, price, how clean is the water, is power available etc. Water is probably the easiest of all liquids to meter and consequently many flow technologies are available to accomplish the task.
