Three problems for liquid level transmitter

- Jul 02, 2020-

Liquid level transmitter is now common tool for measuring liquid level. It often appears in sewage tanks, water tanks, oil tanks, water towers and other places. As a new generation of liquid level measurement tool, it has the advantages of easy installation, stable signal and high accuracy.

Liquid level transmitter ULB6 is now common tool for measuring liquid level. It often appears in sewage tanks, water tanks, oil tanks, water towers and other places. As a new generation of liquid level measurement tool, it has the advantages of easy installation, stable signal and high accuracy. Today we will talk about the three classic problems of liquid level transmitters may occur.

1. Large fluctuation of liquid level

Assuming that the liquid level fluctuates greatly, we need to check it one by one. First, check whether there is a high-power device such as a motor next to the liquid level transmitter. If there is, we need to move the motor out of level transmitter for at least 3 meters, or add anti-interference performance to the liquid level transmitter.

Then we check whether the measured medium has shaking itself, for example, if there are many blisters under the water, we need to find a way to reduce the number of blisters and shaking, or change a measurement tool, such as a radar level gauge.

2. The output value has not changed

If the value has always been a same value and has not changed,we need to check whether the guide hole of the liquid level transmitter is blocked by other objects. If so, clean the objects, and then check whether the internal sensor part is deformed. If there is any deformation, return to the manufacturer for repair.

3. No value display

We connected the liquid level transmitter ULB16 to the control room and found that there is no display output. First check whether the power supply is connected correctly and whether the voltage is between rated power supply . Then check again, whether the wiring itself is OK, if there is no problem, then it is likely to be the problem of the liquid level transmitter itself. The level transmitter needs to be returned to the manufacturer for repair.
