This Dwyer Instruments air velocity transmitter has 16 field selectable ranges

Features & Applications:

This Dwyer Instruments air velocity transmitter is the ideal instrument for monitoring air flow. This transmitter uses a heated mass flow sensor, which allows for precise velocity measurements at various flow rates and temperatures. The 641’s 16 field selectable ranges from 0-250 to 15,000 FPM (0-1.25 to 75 MPS) provide it the versatility to be selected for a multitude of applications. The units 6' cable which connects the sensing probe with the electronic enclosure allows the enclosure to be mounted where it can be more easily accessed.

Features:

  • 16 Field selectable ranges from 0-250 to 15,000 FPM
