DPW201 measures Air Flow and Air Velocity using Differential Pressure measurement. It generates an analog output that can be assigned to DP or Air Velocity or Air Flow.

It is available with; a) single loop-powered 4~20 mA output; b) single loop-powered 4~20 mA / 0~10V output (field selectable); c) dual, isolated, loop-powered, 4~20 mA outputs.

n Measurement of very low pressure applications such as hospitals, fume hoods, computer rooms etc.

n HVAC/building monitoring

n Greenhouse monitoring

n Process system monitoring

n Air economizers

n Duct mount application
