Is the turbine flowmeter in direction?
The turbine flowmeter is the main type of velocity type flowmeter in, when the measured fluid flow through the turbine flow sensor, under the effect of fluid force, the impeller rotation, the rotational speed and the average velocity is proportional to the pipeline, at the same time, the blade periodically cutting electromagnet magnetic flux generated by the coil, the magnetic flux change, according to the principle of electromagnetic induction the Induction EMF ripple in the coil, the electric pulse signal, the electric signal is proportional to the flow pulsation frequency and the measured fluid. Specific, you can refer to Beijing Connathan
Before the turbine flowmeter factory is generally in accordance with the positive calibration, if wrong, will affect the measurement accuracy, but also affect the service life of the flow meter, so as the turbine flowmeter and electromagnetic flowmeter, the installation process is a direction, in the general case are marked with the,
Yes, the general flow meter will be marked with arrows, the direction of the measured medium should be consistent with the arrow.
Because the rotor impeller is made of spiral blades, it can only be measured in one direction.
