2.13.5.1 Calibrating with an Analog Transmitter (Model 310)
An Analog Transmitter (such as the Model 310 normally used by Flowtronex®) converts the pulse
output of the 220B flow meter to a 4 to 20 mA analog signal. The Model 310 is calibrated at the factory
to provide specific full scale outputs based on pipe size. Use the following table to determine the
correct size.
Pipe Size
(Schedule 40)
Max GPM @ 20 mA
2 inch 200
2.5 inch 250
3 inch 400
4 inch" 800
6 inch" 1400
8 inch" 3000
10 inch" 5500
12 inch" 9000
14 inch" 11,500
There are two ways to calibrate the flow, with or without a 4-20 mA signal generator.
