The Meister RVM/U-L4 Flow Switch Monitor is designed to be mounted inline in your pipework, to provide a switch point at your specific flow rate. These Flow Switches are ideal for small pipes where Vane Type Flow Switches aren’t practical to fit. The Flow Switch Monitors operate on a Float measuring principal and can be installed in any orientation. 

The RVM/U-L4 Series are non-indicating flow switches and are only suitable for air and compatible gases.  We have other models for water and oils.
