AQUILA V5 is a bulk water meter designed for water network management and invoicing of substantial quantities of cold water.
It is characterised by its very high measuring dynamic, insensitivity to disturbance and easy maintenance. Its modular rotating flanges make it easy to install on any type of pipe, even when resizing is necessary.
Developed within the framework of the MID, AQUILA V5 complies with the European regulations and holds sanitary conformity certificates.
AQUILA V5 can be fitted at any time with an IZAR clip-on module converting it into a communicating meter ready for mobile reading (walk-by, drive-by, passive drive-by) or fixed network reading (radio/wired).
