The VSAN Ultrasonic AMR Water Meter is an advanced smart water metering solution designed for accurate water consumption measurement and automated remote data collection. Built using Ultrasonic Transit-Time Measurement Technology, the meter delivers highly accurate and reliable flow measurement without any moving parts, ensuring long-term stability, maintenance-free operation, and exceptional durability.
Unlike conventional mechanical water meters, the VSAN Ultrasonic AMR Water Meter eliminates mechanical wear by utilizing ultrasonic sensors to measure water flow. This advanced technology provides superior accuracy over a wide flow range, excellent low-flow sensitivity, and consistent measurement performance throughout the product's service life.
The meter is integrated with an Automatic Meter Reading (AMR) system, enabling remote collection of water consumption data without the need for manual meter reading. This significantly reduces operational costs, minimizes human reading errors, and improves billing efficiency. The meter supports multiple communication technologies, including RS485 Modbus RTU, M-Bus, Pulse Output, NB-IoT, LoRaWAN, 4G/GPRS, and Wireless AMR/AMI solutions (Model Dependent), making it suitable for modern smart water management systems.
The VSAN Ultrasonic AMR Water Meter features a high-contrast LCD display that provides real-time information including instantaneous flow rate, cumulative water consumption, battery status, communication status, alarms, and diagnostic information. The integrated lithium battery offers an operational life of more than 10 years, ensuring reliable long-term performance with minimal maintenance.
Manufactured in compliance with ISO 4064 and OIML R49 standards, the VSAN Ultrasonic AMR Water Meter is suitable for residential, commercial, municipal, and industrial water distribution networks. Its compact design, IP68 protection, and corrosion-resistant construction ensure dependable operation even in demanding environmental conditions.
The meter is designed to seamlessly integrate with SCADA, Building Management Systems (BMS), Smart City Infrastructure, Utility Billing Software, and Industrial Automation Systems, making it an ideal choice for next-generation water management projects.
The VSAN Ultrasonic AMR Water Meter operates on the Ultrasonic Transit-Time Principle.
Inside the meter body, two precision ultrasonic transducers are installed diagonally across the flow path. These transducers alternately transmit and receive ultrasonic signals through the flowing water.
When there is no water flow, the ultrasonic signals travel in both directions at approximately the same speed. As water begins to flow, the ultrasonic signal traveling in the direction of flow reaches the receiving transducer slightly faster than the signal traveling against the flow.
The electronic transmitter continuously measures this extremely small transit-time difference using advanced digital signal processing. Based on the measured time difference, the flow velocity is accurately calculated. By combining the measured velocity with the pipe's cross-sectional area, the instrument determines the volumetric flow rate and totalized water consumption.
The measured data is stored internally and automatically transmitted to the AMR communication system at predefined intervals. This enables utility operators to remotely monitor water consumption, detect abnormal usage, identify potential leakage, and generate accurate billing reports without physically visiting the installation site.
Since the measuring system contains no moving mechanical components, the meter provides excellent accuracy, long service life, minimal maintenance, and stable performance throughout its operational lifetime.
The VSAN Ultrasonic AMR Water Meter is widely used in modern water distribution systems where accurate measurement, automated data collection, and remote monitoring are essential.
