Introducing the latest device – the ADDRA ultrasonic water meter with an integrated valve. The meter and valve are in the same housing, which makes it more cost-effective in terms of price and ease of installation than the meter and valve as separate devices. Due to the absence of moving parts, the water meter with an integrated ADDRA valve is maintenance-free, does not lose measurement accuracy and does not require verification during its lifetime.

This meter has a low starting flow of only 1 liter per hour and a dynamic rate of up to R1600. It also automatically records data and has its own storage for logging information. The LCD display shows the total water flow, signals possible leaks, backflows, and other useful functions. Equipped with a variety of communication interfaces for local access via smartphone, tablet or computer, and communication channels for remote access, the device is a cost-effective solution.

The meter supports credit/prepayment modes of operation. Prepayment is implemented on the basis of the STS standard.
