Application
Cost Savings - By managing water usage more effectively, farmers can reduce their water usage costs, minimize energy consumption, and avoid costly repairs and maintenance.
Easy Installation - Many irrigation water meters are easy to install with minimal technical skills, and they generally require little-to-no maintenance.
Improved Efficiency - New water meter technologies can provide real-time alerts and data on water usage patterns, eliminating the need for manual tracking. This can help farmers manage their irrigation systems more efficiently.
Remote Monitoring - Wireless communication features allow farmers to monitor irrigation water usage remotely, enabling them to track water usage patterns from a central location, reducing unnecessary site visits.

The Operation Description Of The Two Reed Switches System
Please see the diagram of the two reed switches system below, the two reed switches woud be operated “ON” OR”OFF” respectively by the magnet fitted to the pointer or gear during its running on the register, but never “ON” at the same time ,unless the out- magnet attackes.
The two reed switches operate two “ON” and two “OFF” in one round of the pointer or the gear means one signal output, this principle prevent the loss or overcounting of the signal output due to the switches joggling or the pipe vibrating, so assures reliability of the signal output.
Warranty
All meters will be guaranteed against defects in workmanship and materials for a period of one (1) year from the date of acceptance. Defective meters or parts discovered within this period shall be replaced without charge upon return to the S.H.Meters.
