Compact and for high pressures - New: Flow monitor with flow indicator

The flow monitors of the new series RVM/UA-2 expand the application possibilities of the RVM/U-2 series, which have a long record of reliable operation. In the past, applications, which required a mechanical indicator for devices of this size, were not possible. Users were forced to switch to the larger RVM/UM-1 series or other model series.

The new high pressure flow monitors have a length of only 90mm. The mechanical indicator is extremely robust and reliably displays the actual volume flow at all times, without requiring an auxiliary power supply. In the standard version, the flow monitors are employable up to operating temperatures of 120°C; the high temperature versions up to 160°C. The maximum operating pressure for the brass housing is 250bar, and 300bar for the stainless steel version.

Eight standard measuring ranges are available; the smallest from 0.02 – 2l/min, the largest from 8 - 30l/min. If electrical flow monitoring is desired, the switch point can be set by the opertor anywhere within the measuring range. Through the installation of a spring, which returns the float to its inital position, the flowmeters can be operated in any orientation. For electrical monitoring, the floats are equipped with magnets, which energize a reed contact housed separately along side the flow monitor body. Switch contacts are available as normally open or change over. The contacts are completely sealed within the housing and, depending on the connection used, (plug socket or cable), a protection class if IP 65 or IP 67 may be obtained.
