The GEMÜ 800 HP flowmeter has a metering tube in PVDF suitable for inert or corrosive* media. Male threads moulded onto the ends of the metering tube allow for easy mounting of unions. O-ring seals at the faces of the tube ensure reliable sealing between metering tube and union and provide stress-free sealing. The floats are available in PVDF. The scale on the metering tube can be suited to the medium and is available e.g. in l/h, m³/h or %. Dovetail sections moulded onto the metering tube allow for easy mounting of adjustable visual flow indicators, limit switches and a continuous readout transmitter.
