Working principle of turbine flow meter Turbine flowmeter is a kind of velocity flow meter, also called impeller flowmeter, based on the principle of conservation of moment of momentum. When the fluid flows in the pipeline, it impacts the turbine blades, causing the t...
1.2 Working principle When the fluid flows through the meter, the impeller in the meter is driven to rotate, and then through the magnetic coupling between the impeller and the signal detector, the flow rate of the fluid is converted into an electrical pulse signal output, which ...

Product Description Working principle of turbine flow meter Turbine flowmeter is a kind of velocity flow meter, also called impeller flowmeter, based on the principle of conservation of moment of momentum. When the fluid flows in the pipeline, it impacts the turbine blades...
The signal produced by turbine flowmeters is a peak-to-peak voltage pulse. Pulses are most often generated using the principle of reluctance. (See, “Turbine flowmeter principle-of-reluctance operation” diagram.) In the principle-of-reluctance method, a pickup coil is wrapped around a permanent...
This paper explains the general working principle of gas turbine meters and the common causes for metering errors. Field observations and laboratory test examples are presented in this paper to demonstrate these phenomena. The author also suggests methods to ...
Before installing the flow meter, the welding slag and other dirt in the pipe should be strictly removed, and the pipe of equal diameter (or by-pass pipe) should be used to replace the flow meter for purging the pipe. To ensure that the flow meter i...
