Smart level transmitterProbe insertion measurement mode, small size, simple and convenient installation           HART protocol option                                 RS485-MODBUS protocol optionMulti protection structure design, high protection abilityCorrosion resistant stainless steel adopted, applicable to various industry fieldsSupport configuration applicationsPCM266 level transmitter is a fully sealed submerged type liquid level measuring instrument in full stainless steel design. The product adopts high stability and reliability piezoresistive OEM pressure sensor and high precision smart transmitter processing circuit, and applies precision digital temperature compensation technique and non-linearity correction technique. The waterproof cable is hermetically connected to the shell, and the breather pipe is set inside the cable, which can be used in liquid for a long time. The integrated structure and standardized output signal provide convenience for field use and automatic control. The product works in two wire system. It is compact, light-weighted, easy to install and use. It can directly replace the analog output transmitter of 4 ~ 20mA of two wire system. It is applicable to equipment matching and the measurement and control of static pressure level and liquid level in liquid tanks, sewages, industrial water, ponds, wells, rivers, sea, lakes, etc.  Pressure range Pressure range0.5m, 1m, 2m, 5m, 10m, 20m H2OOutput signal Output4 to 20mA + Hart protocol | 4 to 20mA + RS485-MODBUS protocolSpecification Accuracy (linearity, repeatability and hysteresis)±0.5%F.S.

Installation in moving water (rivers, lakes, etc.)Installation tips:1) When measuring the water level in flowing water, when the medium fluctuates greatly, a steel pipe can be inserted in the water channel with an inner diameter of about 50 cm. Make several holes of about Φ5 in diameter on the side of the immersed pipe opposite to the flow direction to allow water to enter the pipe and fix the cable and junction box at the outlet of the pipe. 2) When the medium of the water
