HART Level Sensor


Description of HART level sensor

ULB3351 flange type HART level sensor is one kind of scene transmitter for mounting in pipelines or vessels. Because its isolating diaphragm contacts liquid medium directly, not need pressure pipe to draw out the pressure from positive pressure side (H side), ULB-3351 is suitable for level, pressure, density measurement of high temperature, macro viscosity, easy crystallized, easy precipitated media.

ULB3351 flange type HART level sensor includes plane type and insert type. The mounting flange has 3” and 4” according to ANSI standard. 

The ULB3351 flange type HART level sensor is especially suitable for level, pressure and density measurement of special media (high temperature, macro viscosity, easy crystallized, easy precipitated, strong corrosion) in open or sealed containers.

Features of HART level sensor

▲ Measuring range:0~2.67kPa...2500kPa.
