WHAT ARE THE CHARACTERISTICS AND USES OF LIQUID LEVEL MEASUREMENT TRANSMITTERS?

What is a flange level transmitter? In which industries is it used in life? What are the characteristics of liquid level measurement transmitters? This article will tell you the answers to these questions, let us take a look.

 

Introduction of Liquid Level Measuring Transmitter

The flange type liquid level transmitter is composed of a measuring diaphragm and electrodes on the insulating sheets on both sides to form a capacitor. When the pressure on both sides is inconsistent, the displacement of the measuring diaphragm is caused, and the displacement is proportional to the pressure difference, so the capacitance on both sides is unequal, and it is converted into a signal proportional to the pressure through oscillation and demodulation. The working principle of the pressure transmitter and the absolute pressure transmitter is the same as the differential pressure transmitter, the difference is that the low pressure chamber pressure is atmospheric pressure or vacuum.

 

 

The use of liquid level measurement transmitter

Flange level transmitters are widely used, and are suitable for the continuous measurement of the storage level of various storage tanks and containers in the industrial production process. The instrument outputs a standard DC signal of 0 ~ 10mA or 4 ~ 20mA, which can be used to display, multi-point inspection, recording, control, adjustment and other instruments or PLC, DCS, FCS systems to realize automatic recording and adjustment of the level.

Flange level transmitters are widely used for liquid level measurement of high temperature, high pressure, strong corrosion and other media. The instrument and material contact parts have good corrosion resistance, suitable for continuous monitoring of liquid level, material level, oil-water interface, foam interface in metallurgy, chemical industry, environmental protection, power station, papermaking, pharmaceutical, printing and dyeing, food, municipal and other industries.

 

Advantages of flange level transmitter

The structure is simple: there are no movable or elastic elements, so the reliability is extremely high, and the amount of maintenance is very small.

Easy installation: The built-in structure especially shows this feature, without any special tools.

Convenient adjustment: the two potentiometers of zero position and range can arbitrarily carry out zero point migration or range change within the effective range of liquid level detection.

Widely used: it is suitable for liquid level measurement of high temperature and high pressure, strong corrosion and other media.
