Mini Water Meter

Overview


Mini Water Meter is an ultrasonic water meter technology for residential use by Viewshine. Its technical features include:

High precision: Measurement error is less than ± 2%, with a range ratio of up to R400, suitable for use in scenarios ranging from small leaks to high flow water usage;

Zero mechanical transmission design: no gears or other components, pressure loss is only ≤ 0.03MPa, more wear-resistant than traditional mechanical watches, with a service life of over 12 years;

Ultra low flow perception: capable of detecting ultra fine flow rates of up to 2 liters per hour (such as slow leakage from toilets), helping to reduce non venue water leakage in the pipeline network;

Intelligent judgment: Mini Water Meter can automatically identify abnormal water usage patterns (such as continuous dripping, pipeline bursting), and provide real-time warning through the Internet of Things platform to provide customized water-saving solutions for customers.
