The
meter is suitable both for setting up and for continous flow
measurement. It is intended for permanent installation and must
therefore be specified at the design stage.
Ø 80–630 fullfills tightness class 0 and pressure class A.
The
meter consists of a regulating shutter and a centrally located
measurement plate. Each measurement nozzle has a removable plastic plug
which prevents dirt from entering. It also eliminates air leakage when
measurement is not done.
The unit permits insulation of up to 50
mm thickness to be installed without concealing the measurement nipples
or the label plate.
The plate can be rotated for best legibility,
irrespective of the way the unit is installed and can easily be removed,
to be located away from the unit. The cup around the damper knob allows
insulation up to 50 mm thick to be used. If thicker insulation is
needed, add the special insulation cup IK.
