The performance characteristics of over 6,000 valves – from 80+ manufacturers – are pre-programmed into the AC7-SP+ and this extensive knowledge-base is continually being updated as new valves are introduced onto the market. Valve data files are automatically updated whenever an AC7-SP+ is serviced by us.
A nine-button navigation pad allows simple access to the easy-to-follow menu system and state-of-the-art software allows direct reading of flowrate, differential pressure, percentage of design flow and percentage of target flow. Display backlights ensure that on-screen data is always easy to read, even in the darkest of areas.
The use of tried-and-tested electronics; industry-leading pressure-sensors; highly successful mechanics; bespoke firmware; and an extensive on-board database of valves deliver a powerful, flexible, accurate, easy-to-use tool for the discerning commissioning engineer.

1 x set of T-handle hex keys (3mm, 4mm & 5mm)
1 x screwdriver bit-holder plus PH1 bit
1 x lanyard
1 x strainer maintenance kit
2 x 9V batteries
1 x quick-start guide

Measurement Accuracy |
+/- 1% of reading or +/- 0.1 kPa, whichever is greater Hysteresis = 0.2% span |
Maximum Range | 0.5 kPa to 250 kPa |
Maximum Total System Pressure | 10 bar |
Display Options |
DP & Flow Display — shows differential pressure and flow, along with details of the target valve/device. Normally the most appropriate display option when taking measurements from fixed-orifice & variable-orifice balancing valves. Advanced Display — shows more complex commissioning data and may be preferred to the DP & Flow Display if automatic balancing valves are being measured or if a system of proportional balancing is being adopted. DP Only Display — only shows the measured differential pressure – in large text – and may be preferred when the AC7 is being used as a simple manometer. Velocity (Flushing) Display — shows the derived velocity – in both metric (m/s) and imperial (ft/s) units – and may be preferred when fluid velocities are being measured for the purposes of system flushing. |
Languages | Choose between English, French, Italian & Spanish for the displaying of available menu options. |
Security PIN Code | As per user-preference, set an optional security PIN Code, which will asked for after every battery change. |
Units |
For Differential Pressure, choose your preferred units from: kPa, psi, bar, cmH2O, IWGA (inches water gauge), Ft HD (feet head) or Pa. For Flow, choose your preferred units from: l/s, l/m, l/h, USGPM, UKGPM, m3/h, m3/m or m3/s. |
