DESCRIPTION

A range of manometers measuring differential water pressures up to approximately 12.5m H₂O. Scales are graduated in 1mm divisions.

H12-1: 1 metre scale differential open water manometer
H12-2: 1 metre scale differential pressurised water manometer (the air space above the tubes can be pressurised with the pump supplied)
H12-3: 1 metre scale differential water over Mercury manometer
H12-4: 500mm scale differential water over Mercury manometer
H12-5: 500mm scale differential kerosene over water manometer

Exclusions

Due to its hazardous nature and the severe shipping restrictions, Mercury is not included in Armfield's scope of supply.

Accessories

H12-6: free standing column with height adjustment to take two manometers

H12-7: self-sealing and self-bleeding pressure tapping system which allows a single pressurised water or mercury manometer to be connected into and disconnected from a number of points around a pumped system. The equipment consists of ten self-sealing pressure tapping points with 1/4 inch BSP male threads for fitting into the system and four self-bleeding pressure tapping lines for connection to two differential manometers. Tapping line bleeding is obtained with four in-line vented shut-off valves conveniently mounted on a fixing bracket. The system is supplied complete with a quantity of translucent plastic tubing.
