Product Description

Ultrasonic water meterSH7520

The ultrasonic water meter is an intelligent metering device based on ultrasonic flow measurement technology. It calculates flow velocity and flow rate by measuring the transit time difference of ultrasonic waves in the fluid and integrates communication technology to enable remote monitoring and management.

Product Features

High Accuracy:
Utilizes non-contact measurement technology, avoiding mechanical wear and fluid resistance that could affect measurement accuracy. It can precisely measure water flow velocity and volume, with a low starting flow rate, capable of detecting minute changes in flow speed, ensuring long-term stable measurement accuracy.

Wide Measuring Range:
Supports a wide turndown ratio, such as R400, R800, making it adaptable to various water usage scenarios. It can accurately measure everything from very low to high flow rates.

Low Maintenance Cost:
With no internal mechanical moving parts, there is no mechanical wear, eliminating the need for parameter settings and reducing maintenance caused by wear. There is also no need for periodic replacement of worn components, resulting in a long service life and reduced maintenance costs.

Intelligent Management:
Equipped with various communication capabilities such as LoRa, LoRaWAN, and NB-IoT, it enables remote meter reading for easy management and reduced operational costs. It also features alarm functions for issues such as pipe leakage, providing timely alerts and maintenance notifications to ensure proper operation of the water meter and pipeline system.
