Flowmeter RVO/U-1

RVO/U-1 is a floatmeter (flow switch) for liquids with a scale on the sight glass. The instrument is factory calibrated for upward flow when mounted vertically. However, it is equipped with a spring loaded float that permits installation in any spatial position, including horizontal or vertical with flow in the opposite direction. In this case on-site calibration may be necessary to compensate for the weight of the float.
