Product Description
Product application
District Metered Area (DMA) and Loss Control
In urban water distribution networks, installing bulk ultrasonic water meters can isolate a region (such as a neighborhood or administrative district) from other areas, forming an independent metered zone.
Advantages: Their high accuracy and low starting flow characteristics allow continuous monitoring of minimal night-time flows. If nighttime flow increases abnormally, it can quickly alert that there may be leakage in the network, helping water utilities detect and repair leaks promptly, reducing water wastage and economic losses.
Commercial Premises
Advantages: Ultrasonic water meters have no moving parts and cause minimal pressure loss, so they do not hinder normal water usage in places like shopping malls, saving pump energy. They have a wide measurement range (up to R400), accurately recording both peak water usage and small flows during nights or holidays, avoiding disputes and losses caused by "unmetered small flows."
Agricultural Irrigation Water Measurement
Used for water intake measurement from large canals or main pipelines.
Advantages: They are insensitive to silt and impurities in the water, less prone to clogging, require minimal maintenance, and are suitable for agricultural water environments where water quality is relatively poor.
