Belimo LMV-D3-MFT-RM Volumetric Flow Converter

Belimo LMV-D3-MFT-RM is a remote-mounted volumetric flow controller in the LMV family, designed for VAV-Compact air systems to measure and regulate airflow with an integrated differential-pressure sensor (D3). It delivers precise volumetric flow control by modulating a damper via a 5 Nm torque actuator and supports 24 V power (AC/DC), MP-Bus digital communication, and 2–10 V control signals for compatibility with common building automation. A key feature is Belimo Assistant Link, enabling Bluetooth and USB configuration with NFC and an MP-Bus converter for quick setup. The D3 sensor is suited to very small volumetric flows, enabling accurate control across a wide range of operating conditions, and the unit includes a CAV function with Belimo Assistant 2 settings (CLOSE - Vmin - Vmid - Vmax) that can be mapped in NMV-D2M-compatible fashion for cross-device integration. The RM designation indicates a remote-mount installation option, offering flexible placement in existing ductwork without changing damper hardware. This combination of closed-loop flow measurement, configurable control interfaces, and compact form makes the LMV-D3-MFT-RM well suited for precise zone-level air balance, demand-based ventilation, and energy-efficient HVAC control in commercial applications.
