Flowmeter RVM/U-1

RVM/U-1 float flowmeter (flow switch) for liquids in an all-metal housing. The instrument is factory calibrated for upward flow when mounted vertically from the bottom. However, it has a spring-loaded float, which allows it to be mounted 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.
