There are many kinds of instruments for liquid level measurement on the market, so how to distinguish them, how to choose the right instrument for their own on-site use? Today we will understand the differences between them. Level Switch—— Also known as the water level switch, as the name suggests, it is a switch used to control the liquid level, which is mainly divided into contact and non-contact in form. Level Gauge – A level gauge is an instrument that detects the change in the height of solid materials (solid or liquid) in a container in real time. Level gauges are also known as level transmitters, level controllers, level gauges, level gauges, etc. The level sensor is mainly used to measure the surface position of solid lumps or powders in the silo to know the amount of material stored in the silo. For example, in thermal power plants, it is necessary to detect the position of coal lumps and pulverized coal in raw coal hoppers and pulverized coal bunkers. Level Transmitter – The liquid level transmitter is the extension and development of pressure transmitter technology, which realizes the accurate measurement and transmission of the volume, liquid height and weight of water, oil and paste according to the principle of linear relationship between the pressure generated by liquids with different specific gravity at different heights. 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. The level transmitter also has 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 can be measured with high precision in water, oil and other media compatible with contact materials. 3. The amplification circuit of the liquid level transmitter adopts an integrated chip, wide voltage power supply, good stability and fast response speed. 4. The liquid level transmitter has intrinsically safe explosion-proof and dust-proof capabilities, and can be applied to related dangerous places. 5. The current output of the liquid level transmitter has wiring reverse, overvoltage protection and current limit protection. 6. The liquid level transmitter uses laser resistor 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.
