Construction

The GEMU 840 flowmeter operates according to the part flow principle and consists essentially of three parts: Main flow unit, part flow unit and manual diaphragm valves.

Main flow unit: The material used is PVC-U or PP. The orifice material can be selected as either PVC-U, PP or stainless steel. The body has plain or welded spigots enabling it to be connected by means of unions or flanges.

Part flow unit: Plastic flowmeter which operates according to the variable area principle with integral metering orifice, housing material: polysulfone. The float is made of PVC-U or PP which can also be fitted with a magnet for electrical detection of the flow rate. Dovetail sections moulded onto the metering tube allow for easy mounting of adjustable visual flow indicators (supplied with the flowmeter) and limit switches.

Manual diaphragm valves: The part flow unit can be removed from the main body of the flowmeter without interrupting the main flow by closing the manual by-pass valves.

Advantages
