DPT-Flow-MOD-Series

Airflow Transmitter DPT-Flow-MOD

The DPT-Flow-MOD Modbus airflow transmitter is a multifunctional transmitter for measuring airflow volume, air velocity, differential pressure, and static pressure. It has two functions for airflow measurement. You can either monitor airflow across a centrifugal fan, or connect an airflow volume probe to the transmitter to monitor airflow volume in a ventilation duct. You can use this transmitter with the FloXact airflow volume probe and other airflow probes, pitot tube, or air dampers.

Airflow Transmitter DPT-Flow-MOD

The DPT-Flow-MOD transmitters are typically used in building automation systems for: air flow monitoring across centrifugal fans and blowers, filter monitoring, valve or damper monitoring, airflow volume, air velocity or differential pressure monitoring in ventilation ducts, and airflow or pressure measuring in VAV applications.

This airflow transmitter does not have analogue outputs. The BMS system reads the measurement data directly from the Modbus registers of the transmitter using Modbus RTU communication over the RS-485 interface.

The user interface enables easy selection of settings according to the selected fan or measurement probe.
