The Rosemount 3051SAL Liquid Level Transmitter System is a flexible, 2-wire 4-20mA HART architecture that calculates differential pressure (DP) electronically using two pressure sensors that are linked together with a non-proprietary electrical wire.

Ideal applications for the 3051SAL ERS System include tall vessels and distillation columns that have traditionally required long lengths of capillary or impulse piping. When used in these types of applications, the 3051S ERS System can deliver more accurate and repeatable DP measurements, faster time response, simplified installations, and reduced maintenance.
