Product Information Page

Principles of Operation and Program Instructions:

Flow rate is calculated by using Bernoulli's equation below by measuring the differential pressure across

an orifice plate. The GC52 will be using the orifice plate manufacturer's data of maximum flow rate with

corresponding differential pressure drop.

GC52 Differential Pressure Transducer Flow and integrated Volume Program Guidelines:

Below is an Illustration to program the transmitter in GPM and integrated volume in gallons as the

arbitrary units. Proceed to scale down the transducer range from 40 IWC to 20 IWC. That, is the

maximum differential pressure equivalent to 88 GPM of water (20 mA). Follow the steps below to

rescale and program the transmitter from 0 to 20 IWC of water equivalent to the arbitrary units of 0 to

88 GPM.
