Pressure Level Transmitter

WE3051LT series is a digital flange pressure level transmitter designed for industrial level measurement applications. 3051LT can be configured to provide intergrated solutions for a broad range of pressure and level measurement applications. The principle of the pressure level transmitter (flange level transmitter) is to calculate the current height of the liquid through the change of the pressure of the liquid’s density gauge. The single-flange liquid level transmitter can measure the accuracy of liquid level and density of various containers. There are two types of flat flange and plug-in flange, which are suitable for high-viscosity medium liquid measurement.

The wetted diaphragm materials of pressure level transmitter are SS316L, Hastelloy C-276, Monel, tantalum, etc., which can be applied to the anti-corrosion requirements of different situations and can be based on the measured medium Concentration, humidity, pressure and other parameters are suitable for the corrosion resistance reference table given in the appendix for reasonable selection. Such as strong corrosive occasions can choose anti-corrosion structure transmitter.
