Product details


Fl101-a high precision differential pressure transmitter








Fl101-a is a high degree differential pressure transmitter, which is used to measure the liquid level, density, pressure and flow of liquid, gas or steam, and then convert it into Hart current signal output of 4 ~ 20mADC. Fl101 can also communicate with rst375 handheld terminal or rsmioomodem for parameter setting, process monitoring, etc.








Standard specification: (adjust * range based on standard zero point, stainless steel 316L diaphragm, filling liquid is silicone oil)

Working pressure (silicone oil): rated working pressure is divided into three levels: 16MPa, 25MPa and 40MPa








Static pressure limit: from 3.5kpa absolute pressure to rated pressure, the protection pressure can be greater than 1.5 times of the rated pressure, and added to both sides of the transmitter at the same time.


One way overload limit: one way over dare to reach rated pressure

Electromagnetic compatibility (EMC}: see electromagnetic compatibility schedule below
