The medium flows from below through a glass measuring cone that gets wider on top. Thus, the float is raised and in- dicates the respective flow rate on the scale provided on the measuring cone. To monitor flow rate limits, the URM meters can be optionally furnished with “open collector“ proximity switches. By its special design, this model is particularly suita- ble for applications where only very small operating pressures are available. Another advantage is offered by the very large sight glass which optically allows direct flow observation.
