FLUIDISTOR – GAS FLOWMETER GD 300 EX WITH intermediate flange / WAFER

  • Installation length of 65 mm

  • easy replacement of 99 % built-in flowmeters
    Simple and space-saving installation between ISO and ASME flange

  • Oscillating measurement principle, without moving parts – no wear parts

  • High accuracy (±1,5 % of true value)

  • Measuring range of 1:100
GD300WA-GDR1501

The wafer process connection is the lightest body version for mounting between pipe flanges. 

The device is installed between the pipe flanges and tightened to its place with the bolts of the flanges.
The installation length of the gas flowmeter GD 300 Ex with the wafer process connection is 65 mm regardless of the nominal width (DN). Additionally the wafer process connection is independent of the used flange type.

Therefore a simple and space-saving installation between either ISO or ASME flanges can be realised.
