Flowmeter DUM/A

DUM/A is a floatmeter (flow switch) for liquids in an all-metal housing with a pointer indicator. The instrument is factory calibrated for upward flow when mounted vertically from the bottom. However, it is equipped with a spring-loaded float, which 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.
