The VT-2000 Airflow Measurement Probe consists of multi-sensor probes available as insertion probes or in pre-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
