Description
Flow Meter
The AVG inline flow meter has been developed as 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.
Installation
The AVG flow meter is installed within the pumped solar hot water flow line in a convenient position near the circulation pump. The flow meter can be installed inany position vertical or horizontal and 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.
Comissioning
With the water heater and solar flow and return system fully charged and all the air expelled from the pumped lines the system is ready for commissioning. Using a screwdriver, close or open the regulating
valve to give the required flow indicated by the underside of the red disc on the flow scale.
