The input level transmitter directly into the measured medium is very convenient to install and use. Solid state structure, no moving parts, high reliability, long service life High precision measurement from water, oil to paste with high viscosity, without influence of bubbling, deposition, electrical properties of measured medium, wide range of Temperature compensation. First, the basic working principle of the input level transmitter is the hydrostatic level measurement. Second, the advantages and disadvantages of the input level transmitter 1, the main advantages: 2, shortcomings performance: Radiator Cooling Fan,Auto Radiator Cooling Fan,Car Radiator Cooling Fan,Radiator Cooling Fan Motor ZHEJIANG DEYE AUTOMOBILE PARTS CO.,LTD , https://www.deyemotor.com
In a liquid medium, the pressure generated at a certain depth is generated by the weight of the medium above the measuring point. It is proportional to the density of the medium and the local gravitational acceleration. The formula P=ÏGH reflects the proportional relationship between them. Where P = pressure, Ï = medium density, G = gravitational acceleration, H = depth of the measuring point. Therefore, the physical quantity measured by the input level gauge is actually a pressure, which can be known through the calibration unit MH2O of the input level gauge. The actual liquid level must be obtained by converting the two parameters of density and gravitational acceleration. Such conversions are usually performed by secondary meters or PLCs in the industrial field. 
High measurement accuracy; easy installation; remote transmission of signals;
Different materials can be selected to resist corrosion of various media; suitable for explosion-proof applications; affordable.
The measured signal needs to be scaled; it is not possible to measure temperatures above 125°C for high temperature media; the density of the measured media must be uniform.
