Rosemount 4088B1P1 Multivariable Transmitter

Feature & Principle

It is a multivariable transmitter of Rosemount 4088 series. It integrates three sensing elements to detect differential pressure, static line pressure and process temperature simultaneously. The internal microprocessor compensates pressure and temperature and computes mass flow in real time. It supports Modbus RS485 digital communication to transmit calculated flow data to DCS or flow computer. This compact all-in-one design reduces installation points and improves measurement accuracy for energy and process metering.
