For measuring differential pressure across balancing valves, orifice metering stations, chillers etc. The differential pressure can be accurately related to flow rate. Solid perspex manometers incorporate check valves, over pressure chambers and trap tubes to avoid loss of the indicating fluid. The manometers are tubed to a three valve equalising / isolating manifold. Scale units available as standard are kPa, metres head, feet head, mm w.g. and inches w.g. Adaptors available for connecting the Test Set to most makes of balancing valve.

| All units are leak tested at high pressure before despatch. The sets are supplied with fluid, ready for use, with 3m leads and quick release fittings as standard. Bleed valves rather than screws are used to facilitate bleeding air from the system. | |
| The equalising / isolating manifold has front facing valves. It can be supplied either with the equalising valve upstream of the isolating valves for "easy flushing" of air from the connecting limbs and valve manifold, or with the equalising valve to the manometer side of the isolating valves for "easy zero checking" during operation. | |
| High quality waterproof plywood is used for the cases, preserved and varnished to give long life. Dual cases have lift-off hinges to enable each half of the set to be used at a separate location if required. | |
| Traceable certification to national standards via UKAS calibrated master manometers can be supplied. | |
