1. Product Features:
The card-type ultrasonic water meter adopts the latest circuit design, and its sensitivity and accuracy are greatly improved. The accuracy level is ±2%, the reading is stable, there are no moving parts inside the sensor, and the measurement accuracy is not affected by liquid impurities. It is equipped with Modbus communication protocol as standard, and can add functions such as OCT output. The protection level reaches IP68 and can work for a long time at 2 meters underwater. It is specially designed for agricultural irrigation, garden management, water resources monitoring and other fields. The water meter has low cost, high measurement accuracy, low power consumption, stable and reliable operation, and is only 1 inch (25.4 mm) thick. The water meter uses ultrasonic technology to measure flow. Compared with traditional mechanical water meters, card-type ultrasonic water meters have better performance and a smaller size, especially in realizing remote monitoring and management.

2. Parts Descriptions:
The card-type water meters has wired type as the standard configuration, wireless type need to be customized.
