Turbine Flowmeters measure volumetric flow, where flow passing through the tube is measured as a function of the mean velocity of the streaming fluid. Turbine flow meters may be configured to measure either gas or liquid flow rates. A low mass turbine wheel carried axially in the tube is rotated by the fluid; the RPM of the turbine wheel is directly proportional to the mean fluid velocity within the tube.

SmartmeasurementTM’ s ALTM turbine flow meters come in sizes ranging from 15-300mm (½” to 12”) and feature a wide turn-down with minimum uncertainty and a very repeatable output. The ALTM is excellent for precise measurement of instantaneous flow of low-viscosity fluids such as tap and demineralized water, fuels, liquefied gases, light fuel oils, solvents, and pharmaceutical fluids. Please see the turbine flowmeter matrix below to select the best meter for your application.
