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.
