Show Ratings & Reviews
your gage says it is a flow gage, however in the picture is reading a pressure drop. Is your gage able to display FPM or CFM with a calc factor?
Yes, this model can be programmed to read velocity and even volumetric flow if they are used in conjunction with a flow sensing element, such as a pitot tube.

What is the maximum bidirectional range that can be achieved? (± kPa)
Hello,
The DM-1102 is not bi-directional. It is a uni-directional unit with a range of 0-.25" wc (0-.06 kPa).
