Product Description

Bulk ultrasonic water meter

The bulk ultrasonic water meter is an instrument that utilizes the principle of ultrasound to measure water flow, typically employed in large-capacity pipeline systems. This type of water meter calculates water flow velocity by transmitting and receiving ultrasonic signals, thereby deriving flow data. Compared to traditional mechanical water meters, ultrasonic water meter offer higher accuracy, durability, and resistance to contamination, making them particularly suitable for applications such as large commercial buildings and municipal water supply systems.

Products Features

It has a low-power design and is powered by a large-capacity battery.
Wide range ratio, low starting flow, high accuracy level, good stability, suitable for leak detection.
Optional data measurement and control terminals can realize pipeline assessment, pipeline monitoring, and analysis.
It can be installed at any angle in full pipe conditions, with measurement accuracy unaffected.
Data freezing function, with the ability to set freezing frequency in advance and package for upload.
Forward and reverse metering, suitable for metering environments such as ring pipelines.
An optional pressure sensor is available for pipeline pressure detection.
