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.
