GEMÜ 800 – Variable area flowmeter

The GEMÜ 800 flowmeter operates according to the variable area principle. Metering tubes are available in PA transparent or Polysulphone suitable for inert or corrosive* media (PVC-U and PVDF tubes on request). 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 stainless steel 1.4571, PVC-U, PP or PVDF (depending on working medium and measuring range). 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.
