Extensive Valve Database – At Your Fingertips!

The performance characteristics of over 5,000 valves – from 70+ manufacturers – are pre-programmed into the AC7 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 is serviced by us.

Simplicity

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.

Sophistication

The use of sophisticated electronics and highly successful mechanics mean that high levels of accuracy are consistently achieved. The AC7 is particularly suited to modern systems with higher differentials being measured across differential pressure control valves and some automatic balancing valves.

AC7-HP Manometer Technical Specification

Measurement Accuracy

+/- 1% of reading or +/- 0.2 kPa, whichever is greater

Hysteresis = 0.2% span

Maximum Range

1.0 kPa to 800 kPa

Maximum Total System Pressure

20 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.

Flow Only Display — only shows the derived flow – in large text – and may be preferred when fluid velocities are being measured for the purposes of system flushing.

Valve Storage

Up to 100 storage locations can be used for the storing of ‘live’ commissioning data while on site.

Help

Context sensitive help is available for all functions. Dedicated button available for help.

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.

For Velocity, choose your preferred units from m/s or f/s.
