The VT2000 Airflow Measurement Probe consists of multi-sensor probes available as insertion probes assembled airflow stations. Individual sensors provide frequency pulse outputs which are directly proportional and linear to airflow velocity. These digital signals are totalized in the companion transmitter and are converted to a 4-20mA, 1-5 or 2-10 VDC output, linear to flow. Units are available with one to four sensors, in sizes as small as 4″ diameter up to four square feet. Either 24 VAC or 15 to 35 VDC power is required for operation.
Applications
- Specifically designed for use in small ducts as a high performance alternative to Pitot stations with velocity pressure transmitters, and thermal devices.
- Flow measurement applications in industrial and process flow measurement, semi-conductor, and pharmaceutical.
- Cleanrooms.
- Laboratories.
- Animal rooms.
- Operations rooms.
- HEPA filter systems where flow monitoring is critical to system performance.
Advantages
- Linear sensor output.
- True velocity averaging.
- Drift-free operation.
- Ten-to-one flow turndown.
- Impervious to dirt and other suspended materials in the airstream.
