Product Description

Ultrasonic water meterSH7520

The ultrasonic water meter is a smart water meter that uses ultrasonic principles to measure water flow velocity and calculate the flow rate accordingly. Compared to traditional mechanical water meters, ultrasonic water meters offer higher accuracy, sensitivity, and durability, making them especially suitable for scenarios with complex water quality conditions.

Product Features

High-Precision Measurement

Ultrasonic water meters use non-contact measurement technology, avoiding the impact of mechanical wear on measurement accuracy. They can precisely detect even small changes in water flow, providing reliable data support for refined water resource management. Whether it's for daily household water usage or large-scale water monitoring in commercial settings, ultrasonic water meters ensure accurate and reliable recording of water consumption.

Long Service Life

With no mechanical moving parts, ultrasonic water meters are free from wear and fatigue issues, resulting in a much longer service life. Compared to traditional mechanical water meters, they significantly reduce the frequency of replacement and maintenance, lowering management costs. Additionally, these water meters are made with corrosion-resistant materials, enabling them to withstand harsh water qualities and environmental conditions, further enhancing their reliability and stability.

Smart Functions

Ultrasonic water meters are equipped with advanced communication modules and offer powerful smart features. They can collect and store real-time data such as water usage, flow rate, and pressure, and transmit this data to a remote management platform via wireless communication technologies such as NB-IoT and LoRaWAN. This enables remote meter reading, real-time monitoring, and data analysis.

Working principle

The ultrasonic water meter calculates the flow velocity of water by using the time difference of ultrasonic waves traveling in the downstream and upstream directions. When ultrasonic waves propagate through the pipe, their speed increases in the downstream direction and decreases in the upstream direction. By precisely measuring the time difference between the two directions, the water flow velocity can be determined, and consequently, the flow rate can be calculated.
