Wireless wet valve-controlled cold water meter

Wireless wet valve controlled cold water meter
The LXSF-15FW~25FW series wireless valve controlled cold water meter is a water metering instrument that uses the rotor liquid seal cold water meter as the base meter, and uses various electromechanical conversion methods and wireless communication technology for data remote transmission and remote valve closing to centrally manage water consumption.
Features:
1. The messaging module and the base meter adopt a separate structure, and the power supply battery is independently packaged for easy battery replacement;
2. Adopting current mainstream data transmission technology and advanced network topology structure, the signal is stable and reliable;
3. The DN15 to DN25 signaling positions can be measured in 1L or 10L positions according to demand, with high measurement accuracy and can meet different needs;
4. The base table adopts an independent trust pointer, which does not affect any readings;
5. Special calculation algorithms are used to ensure the accuracy of counting, which often occurs during the use of water meters due to the backflow and shaking of water flow, resulting in repeated counting.
