The AVG inline Flow Meter- 2.5L is normally used with evacuated tube systems and has been developed as a guide for the plumber when commissioning the installation of a split solar hot water heater. The flow meter is designed using DR brass for resistance to dezincification and high temperature seals and plastic components to resist the high temperatures found in solar hot water heaters.
The AVG flow meter is installed in a convenient position near the circulation pump and can be installed in any position vertical or horizontal within the pumped solar hot water flow line. Care should be taken to ensure that the directional arrow marked on the valve is pointing in the direction of the flow. The flow meter comes complete with a built in regulating / isolating valve and easy to read flow rate scale.
