AC7 units are recommended for use in the Middle East; for the UK market we would suggest the AC6 version. Note that there is no protective rubber boot supplied or available for the AC7.
The AC7 electronic manometers from Comdronic designed specifically to measure hydraulic differential pressure across balancing valves and orifice plates up to a maximum system pressure of 20 bar & fluid temperatures (at the sensor) from 2 to 50 °C. The instruments incorporate an easy to use menu system with a large “graphical” display and this comes in a rugged 3D-printed enclosure. With state-of-the-art software and an extensive database of balancing valves to provide a direct reading of flow as well as differential pressure, percentage of design flow and the target flow.

Features
Simplicity
Unlike any other commissioning unit, the most commonly used functions - Flow and Pressure - are shown as the default screen from the display menu. This means that for general commissioning purposes the most valuable data is shown at the touch of a button - in large text.
The keypad allows simple navigation through a menu system which provides the option to select the most appropriate screen for the work being carried out. The 'Multi Display' has the ability to show more complex commissioning data and it can be set to the 'Flow / Pressure Display' if automatic balancing valves are being measured, or if a system of proportional balancing is being adopted. Alternatively, the 'Pressure Display' is the simplest option available and is designed for applications where the device is being used as a simple manometer.
Sophistication
Accuracy of measurement is of course one of the most important elements of the function of commissioning units. The Comdronic AC7-SP+ gives differential pressure readings to an accuracy of ± 1 % of reading or ± 0.1 kPa whichever is the greater. The AC7-HP+ has an accuracy of ± 1 % of reading or ± 0.2 kPa whichever is the greater. A user-adjustable damping system further improves reading confidence on unstable systems.
Convenience
Designed to be as portable as possible, the compact and lightweight handset is easily operated in the hand or may be clipped to a lanyard. The complete Comdronic AC7 units includes a handset a pair of connection tubes with integral isolation valves; two sets of Binder-style adaptors; a screwdriver 3, 4 & 5 mm Hex Keys, complete with a set of user instructions; quick stat guide and calibration certificate. All in a rigid plastic carry case with profiled foam inserts for added protection during transportation between sites.
