Overview
The UMC4 transmitter in a rack-mount housing is designed for Coriolis mass flow measurement systems. It delivers synchronized mass flow, density and temperature data suitable for demanding industrial processes and custody-transfer applications.

Highlights

• Compact rack-mount format for space-constrained installations
• Configured for hydrogen refuelling station requirements

Key description
The UMC4 processes signals from Coriolis sensors to provide accurate mass flow, density and temperature outputs. It supports liquids, gases and slurries and supplies reliable measurements for process control and metrology.

Exceptional accuracy for demanding applications
The transmitter delivers repeatable mass flow and density values required for process control and custody transfer, with integrated compensation for temperature and pressure variations.

Features

• Multivariable measurement: Simultaneous mass flow, density and temperature outputs reduce instrumentation complexity.
• Real-time data processing: Fast signal processing for prompt feedback to control systems.
• User-centric design: Clear operator interface for on-site configuration and status checks.
• Versatile communication: HART, Modbus and Profibus compatibility for system integration.

Built for harsh industrial environments
The rack-mount housing is engineered for installation in industrial control cabinets and protected environments, with electronic design to withstand typical temperature and contamination ranges.

Versatility across industries
Adaptable to chemical, oil & gas, energy and food & beverage sectors as well as hydrogen refuelling stations where precise mass and density measurement is essential.

Easy integration, maximum efficiency
Compact footprint and standardized communication interfaces allow direct integration with Heinrichs Coriolis flow sensors and third-party control systems to streamline commissioning.

Driving operational performance
Advanced diagnostics, adaptive algorithms and data logging support preventive maintenance and process optimisation strategies.

Applications
Designed for use with Heinrichs Coriolis mass flow meters of the TMU, TMU-W, HPC, TM and TME series. Rack-mount format is particularly suited to hydrogen refuelling station installations.
