Siemens 7ME4400-1GD10-1AA1 SITRANS FC300 Mass Flowmeter Unit

Module Feature

7ME4400-1GD10-1AA1 is the single-tube Coriolis mass flow sensor of Siemens SITRANS FC300 series.

It can directly measure mass flow, medium density and process temperature simultaneously, not affected by pressure, temperature and viscosity variation. The compact single tube design reduces pressure drop. It supports integration with corresponding transmitter, and outputs 4-20mA or digital communication signal. Widely stocked as maintenance spare for chemical, oil & gas and food processing flow monitoring skid.

Working principle

The vibrating measuring tube produces Coriolis effect when medium flows through.

Vibration phase shift is detected by internal sensors, converted into mass flow value. Density is calculated from tube vibration frequency, and temperature signal is collected by built-in RTD. The measured data is sent to transmitter for processing, display and transmission to DCS system.

Onboard components

Vibrating single measuring tube, pickoff sensor, drive coil, RTD temperature sensor, sealed sensor housing, wiring terminal and pressure containment structure.

LED indicators

Status indicators are located on the matched transmitter unit.

Hardware self‑diagnosis

Sensor monitors tube vibration, signal amplitude and temperature sensor health. Configuration and calibration are completed by Siemens flow device software.

Programming software

Siemens Flow Tool, used for range setup, density calibration and diagnostic data reading.

Electrical & Process Parameters

Installation

Depressurize pipeline before replacement.

Install sensor at proper straight pipe section, avoid strong vibration interference, connect sensor cable to transmitter, perform zero calibration, test flow response and signal output after commissioning.

Interface

Special signal cable port for transmitter connection, thread or flange process connection.

Diagnostic

No flow signal: Drive coil fault, excessive medium bubble, serious vibration interference. Density deviation: Need zero and density recalibration. Sensor fault alarm: Pickoff sensor damage or wiring break.
