The Meister RVO/U-4 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 RVO/U-4 Series are an In-Line Flow Switch with a glass indicating window, only suitable for water and compatible liquids.  We have other models for air/gas and oils.
