How does a turbine flowmeter calculate the impeller speed?
The turbine flowmeter is a pulse signal, the impeller speed should be measured, you use the frequency meter, the measurement time, measured the number of pulse frequency, and then according to the relationship between the frequency and time of every rotation speed can be calculated.
Measure the time, measure the number of pulses, then calculate the revolutions based on the number and time of each turn.And Shunda VN series turbine flowmeter
Turbine flowmeter is a pulse signal, the impeller speed should be measured, you use frequency meter
