The ASN-SU-V operates on an ultrasonic measurement principle based on the transit-time difference of sound waves traveling through the water flow path. This technology provides exceptionally high measurement accuracy and negligible pressure loss without the need for mechanical components, resulting in long service life and stable performance.

In addition to the core features of the standard ultrasonic model, this valve-controlled version is equipped with an integrated electric control valve that allows automatic remote shut-off and restoration of water flow. This functionality can play an effective role in subscriber consumption management, intelligent network control, debt management, and water loss reduction.

Additional advantages of this meter include the ability to measure very low water flow rates due to its low starting flow threshold, transmit data and connect to data management and remote reading systems (AMR/AMI), automatically detect leaks and post-meter pipe bursts, and record both consumption data and operational events. The meter is also capable of detecting different types of tampering. By combining precise ultrasonic measurement with flow control capability, the ASN-SU-V serves as a key tool for intelligent water consumption management in residential and urban applications.
