Maintenance of Submersible Level Transmitters

1.Freeze protection measures

During winter months, when the submersible level transmitter is installed outdoor, it must be protected against freezing to prevent liquid expansion within the pressure inlet from damaging the sensor.

2.Wiring protection

When wiring, route cables through waterproof connectors (accessories) or hoses, and tighten sealing nuts to prevent rainwater ingress into the transmitter housing via the cable.

3. Installation position

For dual-flange level transmitters, ensure the sensor's pressure-conducting tube is installed in an area with minimal temperature fluctuations.

4. Avoid liquid impact

When measuring liquid pressure, position the flange level transmitter to avoid liquid impact (water hammer effect) to prevent sensor damage from overpressure.

5. Avoid sedimentation

When measuring liquid pressure with a dual-flange level transmitter, open the pressure port on the side of the process pipe to prevent sedimentation and residue accumulation.

6.Avoid corrosion and high temperature

It is essential to prevent the flange liquid transmitter from contacting corrosive or excessively hot media, and to prevent scum deposits within the pipeline.
