2. Product Overview

The HDIL type IC card intelligent drinking water cold water meter is produced according to the GB/T778-2007 standard. All performance indicators of this water meter meet the requirements of GB/T778-2007 and the Ministry of Construction standard CJ/T133-2012. It is used to measure the total volume of water flowing through the water pipeline and is suitable for one-way, non pulse water flow. The water meter is a high-quality product that integrates functions such as prepayment, automatic billing, status alarm, and prevention of improper use. It is based on a non faulty, ordinary wet cold water meter, equipped with a highly reliable automatic control device and a pressure loss free motor control valve with ultra-low power consumption and high torque output. It has the characteristics of accurate measurement, reliable performance, advanced structure, clear and intuitive reading, and long service life.

3. Application field: This product is mainly used for measuring and charging water usage in residential and enterprise institutions. This water meter is an ideal measuring and charging instrument for modern management of water management departments such as water companies and property management companies.
