AQUILA V4 is a bulk water meter designed for network metering and invoicing of substantial quantities of cold water. It is characterised by its very high measuring dynamic, its insensitivity to disturbances and easy maintenance.
Developed within the framework of the MID, AQUILA V4 complies with the European regulations and holds sanitary conformity certificates.
Modular, AQUILA V4 can be fitted at any time with an IZAR clip-on module converting it into a communicating meter ready for mobile or fixed (radio/wired) network reading.
