To smooth out flow fluctuations and noise on gas

flows, a dashpot damper is built in. This is suitable

for clean gases where particulate matter is less than

50 microns.

Std variants available for low pressure drop applica-

tions, using PVC float assemblies See catalogue for

full details. Specify line pressure and flow range

when enquiring.

INSTALLATION NOTES

1.

The instrument should be installed vertically in the pipework with the direction

of flow vertically upwards.

2.

Ensure that any ferromagnetic material is clear of the body and indicator case

by 100mm minimum.

3.

The upstream and downstream pipe bores should be the same nominal size as

the instrument. Straight pipe lengths of 5 diameters upstream and 2 diameters

downstream should be provided if possible.

4.

Before the meter is installed, the pipeline should be checked, cleaned and

flushed to eliminate any foreign matter. An appropriate filter should be fitted

upstream if any particle present is likely to be greater than 50 microns.

5.

Solenoid valves should not be used where they act directly on the instrument.
