Turbine Flow Meter Operating Principle Fluid entering the meter first passes through an inlet flow straightener that reduces its turbulent flow pattern. Fluid then passes through the turbine, causing the turbine to rotate at a speed proportional to fluid velocity. As each turbine blade passes through the magnetic field generated by the meter’s magnetic pickup,…
Oval Gear Flow Meter Oval gear meters are traditional, mechanical, positive displacement (PD) flow meters, first invented more than 50 years ago by OVAL Corporation of Japan and now widely used for flow metering applications. A very precisely adjusted gear pair within the casing forms the measuring element. The in flowing medium causes the gear…
Ultrasonic Clamp-on Flow Meter Ultrasonic flowmeters utilize sound waves to measure fluid flow velocity. They operate on the principle of transit time, where ultrasonic waves are transmitted in both upstream and downstream directions. The difference in travel time between the two signals is directly related to the fluid’s flow velocity. Transit Time Measurement: Ultrasonic flowmeters use two transducers…
Vortex Flow Meters The vortex flowmeter is a volume flowmeter that is researched and produced according to the Karman vortex principle to measure the volume flow of gas, steam, or liquid, the volume flow of the standard condition, or the mass flow. Vortex flow meters measure fluid velocity using a principle of operation referred to…
