ST3000 Smart Transmitter Series 900 Electronic Differential Pressure/Pressure Transmitter 4-13
Recommended Piping -- Example 2
The illustration shows a typical example for Gas Flow Rate Measurement. This Differ-
ential pressure transmitter is located above the differential pressure output port of the
process pipe.The condensate drains away from the transmitter.
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, check for pressure leaks around the
3-way manifold valve, and the transmitter.
