On the market, there are many kinds of instruments for liquid level measurement, how do we distinguish them, how to choose the right instrument for our own field use? Today, let’s learn about their differences with the editor of Xingyi.
Level switch Also known as water level switch, as the name suggests, it is a switch used to control the liquid level. From the form, it is mainly divided into contact type and non-contact type.
Level meter Level meter refers to an instrument that detects the change in the height of solid materials (solid or liquid level) in a container in real time. Level meter is also known as level transmitter, level controller, level meter, level meter, etc. The level meter is mainly used to measure the surface position of solid blocks or powder in the storage silo to understand the amount of substances stored in the silo; In thermal power plants, it is necessary to detect the position of coal blocks and pulverized coal in raw coal hoppers and pulverized coal silos.
Level transmitters The liquid level transmitter is an extension and development of pressure transmitter technology, according to the principle of linear relationship between the pressure generated by different specific gravities of liquid at different heights, to achieve accurate measurement and transmission of the volume, liquid height and weight of water, oil and paste.
Level transmitters are widely used in drinking water systems, water level overflow weirs, pumping stations, liquid tank level measurement, water treatment plants, water circulation and other working conditions. Level transmitters also have the following features: 1. Simple installation, cable connection, can be directly put into the site. 2. The liquid level transmitter adopts stainless steel shell, which has a long service life, and water, oil and other media compatible with contact materials can be measured with high precision. 3. The amplification circuit of the liquid level transmitter adopts integrated chip, wide voltage power supply, good stability and fast response speed. 4. The liquid level transmitter has the explosion-proof ability of intrinsic safety and dust case, and can be used in related dangerous places. 5. The current output of the liquid level transmitter has reverse wiring and overvoltage protection and current limit protection. 6. The liquid level transmitter uses the laser resistance adjustment process to compensate for zero point and sensitivity temperature in a wide temperature range. 7. The output signal has 4-20mA current output, RS485 digital signal output, customized voltage output, strong anti-interference ability, and long transmission distance.
