Flange-type and Insert-type Liquid Level Transmitter
1. Product Brief Introduction:
The sensor part of the HQ-2088 series high-temperature liquid level transmitter can be directly inserted into the liquid, and the transmitter part can be fixed with a flange or bracket.
2. Product Features:
High precision measurement, wide range temperature compensation unaffected by foaming, deposition, and electrical characteristics of the measured medium;
Solid state structure, no moving parts, high reliability, long service life, can be processed from water, oil to viscous paste;
Good stability, high precision, and can work in high temperature environments;
Directly put into the tested medium, installation and use are quite convenient.
