Product details
Fl101 differential pressure level transmitter
1, application
The bellows of differential pressure liquid level transmitter is used to prevent the medium in the pipeline from directly entering the pressure sensor assembly of differential pressure transmitter, and the filling liquid such as silicone oil is used to transfer the pressure between it and the transmitter.
Fl101 liquid level transmitter is used to measure the liquid level, density, pressure and flow m of M liquid, gas or steam, and then convert it into 4 ~ 20mADC Hart current signal output. Fl101 can also communicate with st375 handheld terminal or rsmioomodem for parameter setting, process monitoring, etc. The M range of fl101 series liquid level transmitter (when not moved) is 0-1kpa ~ 2MPa, and the rated pressure of liquid level flange is respectively 1.6/4mpa, 6.4/4mpa
10MPa, 150psi, 300PSI or 600psio
2. Working principle and structure
Fl101 differential pressure liquid level transmitter is composed of fl101 series differential pressure transmitter and welded liquid level flange. Its working principle is the same as that of fl101 series differential pressure transmitter (refer to the technical specifications of fl101 series differential pressure transmitter), but the pressure transmission path on the positive pressure side is slightly different: the pressure acting on the high pressure side first passes through the diaphragm and filling liquid on the liquid level flange, then passes through the transmitter body, and finally reaches the high pressure side of the m-sensor.

Output signal limit: 1min = 3.9ma, Lmax = 20.5ma
Bitter current (mode can be set}
Low alarm type (minimum): 3.7 Ma
Low alarm type (minimum): 21 Ma
Non alarm type (hold): keep the effective current value before fault alarm current standard setting: high alarm type
5. Response time
The damping of amplifier is usually 0.1s, and the time constant of sensor and liquid level flange is 0.2S, which depends on m-pass and m-pass ratio. The additional adjustable time constant is 0.1-60s.
6. General conditions
6.1 installation conditions
The level flange transmitter can be directly fixed to any position 3. The best condition is to make the process flange axis vertical, and the position s deviation will produce the zero position deviation which can be corrected. The electronic meter can rotate 360 ° at most, and the positioning screw can fix it in any position.
6.2 environmental conditions

6.3 process medium limit:
Medium temperature limit: - 3cm 80 * 0
Pressure limit of transmitter body: from 3.5kpa absolute pressure to rated pressure, protection pressure can be greater than rated pressure
1.5 times of that of the transmitter.
Rated pressure of liquid level flange: ANSI standard: 150psi ~ 600psi
DIN standard: pn1.6mpa-pn10mpa
One way overload limit: the low-pressure side is the rated pressure of the transmitter body, and the high-pressure side is the rated pressure of the liquid level flange, which may cause
Zero drift that can now be corrected.
