Level meter Considerations
Feb 10, 2018

With the development of industry, liquid level sensors are increasingly used in the industry, in the use of transmitters, we need to pay attention to some problems, so that not only to make our measurement more accurate, but also make our liquid level sensor to use longer life. Take a look at all the things you need to be aware of:

1, do not use above the 36V voltage to the transmitter, otherwise it will cause damage to the transmitter;

2, do not touch the diaphragm with hard objects, otherwise it will cause the isolation of the diaphragm damage;

3, liquid level sensor measurement of the media does not allow icing, or damage sensor components isolated diaphragm, resulting in damage to the transmitter, when necessary to the transmitter for temperature protection, to prevent icing;

4, in the measurement of steam or other high-temperature media, the temperature should not exceed the liquid level sensor when the limit temperature, higher than the use of variable liquid level sensor limit temperature must use the heat dissipation device;

5, the measurement of steam or other high-temperature media, should use the heat pipe, so that the liquid level sensor and pipeline connected together, and the use of pressure on the pipeline to the transformer. When the measured medium is water vapor, the heat pipe should be injected with the right amount of moisture to prevent superheated steam directly contact with the liquid level sensor, damage the sensor;

6, in the pressure transmission process, should pay attention to the following points,

A, the liquid level sensor and the heat pipe connection place, do not leak;

b, before starting to use, if the valve is closed, then use, should be very careful, slowly open the valve, so that the test medium directly impact liquid level sensor diaphragm, thereby damaging the sensor diaphragm;

C, the pipeline must be kept open, the sediment in the pipe will eject, and damage the sensor diaphragm.
