Wireless water meter:
1.Application:
Wireless remotely measuring the volume of cold flow water passing through the pipeline.
Minsen wireless smart water meter is high-tech product which integrates the electrical and mechanical parts, adopts advanced wireless communication technology, converts the data of traditional mechanical meter into electrical signal and stores it by microelectronic control circuit. The meter measuring data can be automatically read via GPRS network or via wireless meter reading devices and then transmit to utility management system.
Design concep
Lifetime of electronic part is longer than ten years, but the battery operating cycle is six years, and the cost can be significantly reduced by replacing battery.
Design features
Adopting battery seal case with open and spiral structure, which will ensure both reliable sealing and easy replacement.
2.Mechanism Features :
- Wet Type
- Class B
- ISO 4064 standard
