Emerson Micro Motion 2700 Flow Transmitter Unit

Module Feature

2700R12ABAEZZZ belongs to Emerson Micro Motion 2700 series field mount multi-variable transmitter. It matches full range of Micro Motion Coriolis flow sensors. It measures mass flow rate, volumetric flow, fluid density and process temperature simultaneously. It supports HART, Modbus communication, local LCD display and two-button operation. Built-in totalizer, batch control, concentration calculation and comprehensive device diagnostics. Explosion-proof field housing, suitable for hazardous area installation. Widely applied in oil & gas, chemical, food & beverage for trade transfer and process control.

Working principle

The transmitter receives frequency and temperature signals from Coriolis sensor tube. Internal processor calculates mass flow, density and temperature by proprietary algorithm. It outputs 4-20mA analog signal and superimposes HART digital data. It continuously monitors sensor coil resistance, tube drive status and signal quality, stores event logs and alarm records, and uploads data to DCS or flow computer.

Onboard components

Main control PCB, HART communication chip, LCD display, local push buttons, power regulation circuit, status LED array, aluminum alloy explosion-proof housing, sensor interface terminal block.

LED indicators

Power LED, Run LED, Fault LED. Measurement data and diagnostic codes are shown on LCD screen.

Hardware self-diagnosis

Sensor coil fault detection, drive amplitude monitoring, signal loss diagnosis, loop current check, memory integrity test, temperature monitoring.

Programming software

Emerson AMS Device Manager, Micro Motion ProLink, used for range configuration, batch setup, density calibration and firmware upgrade.
