flow transmitter for hvac systems
DPT-Flow is a flow transmitter that provides an easy way to measure the flow rate on centrifugal fans or in a duct system. One device is suitable for a range of fan types. It can also be used with several different measurement probes such as FloXact™ or pitot tube, and air dampers.
The DPT-Flow can be used to measure the airflow on centrifugal fans or as a transmitter to regulate the airflow in a duct or on the selected fan or blower. It can also be used in a duct system or in air-handling units as an on-site display for flow.
The DPT-Flow is an ideal instrument for airflow monitoring and control, and fan and blower control.
Accuracy (from applied pressure): (models 1000 and 2000)
Accuracy (from applied pressure): (models 5000 and 7000)
Zero point calibration:
Output signals for pressure and airflow (selectable by jumper):
Pressure < 125 Pa = 1 % + ±2 Pa
Pressure > 125 Pa = 1 % + ±1 Pa
Pressure < 125 Pa = 1.5 % + ±2 Pa
Pressure > 125 Pa = 1.5 % + ±1 Pa
