Are the Flo-Sensors sensitive to mounting orientation?
Yes, the flow sensors, like conventional ball and tube flow meters, are sensitive to mounting orientation and have been tested at factory in horizontal position. Units can be recalibrated vertically or on their sides but calibration data will differ. Refer to INSTALLATION information on page 4 of X-100 instruction manual. Models 100-3 and 100-4 only operate horizontally.
