Rotary Gas Flow Meters
Reliability, simple maintenance and an extended operating range while maintaining the measurement accuracy.
The KET-CGP-000 series rotary piston meters represent a valid alternative to those of the turbine type, being particularly recommended for systems that operate with frequent flow transients.
The body, made of aluminium, is strong, light and small in size. The rigid frontal support absorbs any forces resulting from the imperfect alignment of the pipes. The mechanical indicator and the impulse emission system are housed in a sealed anti-condensation drawer.
They are available in two versions: single (KET-CGP-000) or double case (KET-CGP-000.T) pistons. The TWIN variant has the advantage of eliminating the pulsation effect of the flow to the advantage of quiet operation.
Maintenance is simplified as the oil level indicators and lubrication connections are accessible from the front and the gauge can be installed in direct contact with any rear wall.
