Wireless Internet of things water meter
Direct drinking water remote transmission water meter (DN15)
Detailed Introduction
Product principle
A type of electronic remote transmission water meter that adopts a mechanical rotary piston metering structure and the principle of volumetric metering. It collects water meter data by sensing the number of turns of the semicircular steel plate pointer on the base meter.
Product features
·The case is made of 304/316L new generation food grade stainless steel, which is acid alkali resistant and high temperature resistant, ensuring no secondary water pollution caused by the case material.
·Volumetric metering mode, with inner diameter of 8mm, good performance in small flow and metering accuracy of 0.01L.
·The remote data is accurate to liters, and real-time water data can be captured for analysis.
·With a split structure, the entire electronic unit can be replaced independently, and the battery life is more than 8 years.
·Valve control components can be selected according to management needs to remotely control valve opening and closing.
·Various communication modes such as NB IoT/Cat.1/WLAN/satelliete communication can be selected, and can be combined randomly according to the site conditions to achieve different customer needs.
