Wireless remote transmission cold water meter is used to measure the total volume of water flowing through the tap water pipeline measurement instrument, the new type of water meter, the use of new technology, novel design, reasonable, excellent material selection, beautiful appearance, precision assembly, easy maintenance. This series of wireless remote cold water meter is based on the mature mechanical cold water meter to add electronic automatic sampling counting, wireless data transmission, remote and other functions, convenient management department remote monitoring and management.
peculiarity
2.1 Without wiring, it is a measuring instrument for the modern management of remote meter reading in new residential areas, old areas and park construction;
2.2 Easy maintenance and replacement, intelligent module and base table can be split;
2.3 The rotor wet liquid-sealed base table has high sensitivity and small initial flow rate;
2.4 Special structural design, advanced testing means, reliable signal acquisition;
2.5 Do not change the technical indicators of the original water meter, retain the original wet liquid-sealed water meter word wheel display reading function;
2.6 High reliability sensor, strong anti-interference, long service life;
2.7 It can be combined with the meter reading system to establish a remote automatic meter reading management system to truly realize the automation of meter reading;
