Turbine Flow meter Coefficient and Scaling Factor

A digital turbine flowmeter generates 10 pulses per gallon of liquid passing through it. Determine the meter coefficient and calculate the scaling factor that are needed to develop an output in which each pulse would represent 100 gallons.

Solution:

The meter coefficient is as follows:

K = Pulses / Volume

so as per above inputs, K = 10 Pulses / gallon

The scaling factor is as follows:

 = (10 pulses/gallon) x (100 gallons)

= 1000 pulses

Therefore, a scaling factor of 1,000 is necessary to ensure that the flowmeter’s digital circuit generates one output pulse for every 1,000 pulses generated by the magnetic pickup coil.
