4-3-1 :Piping for Liquid, Gas or Steam Flow Rate Measurement

Recommended Piping -- Example 1

The illustration shows a typical example for liquid Flow Rate Measurement. This Dif-

ferential pressure transmitter is located below the differential pressure output port of

the process pipe.This minimizes the static head effect of the condensate.

The following apply:

Grade the pipe at the differential pressure output part.

Inclination symbol in illustration: Low level High level

After piping work, ensure that the connecting pipe, the 3-way manifold valve, and the

transmitter have no pressure leak.
