Flow Rates: Water meters are typically rated according to their flow rates, which determines how much water can pass through the meter in a given amount of time. Irrigation systems typically require meters with high flow rates to accommodate the volume of water used for irrigation.
Accuracy: The accuracy of the water meter is a critical feature to ensure precise measurement of the water usage. It is essential to choose a meter with an acceptable degree of accuracy, especially for irrigation systems that are subject to water-use guidelines and regulations.
Optional Features
·Plastic register, copper register and full glass register.
·Accuracy: R=25/20/50/class a.
·Size: DN50-DN300.

·Water meter temperature: 40℃-90℃
·Reed switch option.
·Flange standard can be choose.
·360 degree rotate can be choose.
·Cast iron, Ductile iron, stainless steel,GG25,GGG50,SS304,SS316 body can be choose.
·Working pressure: PN16/25.
·Provide pulse output/rs485 modbus/wired remote/pulse splitter/pulse read display
Working Condition
·Water temperature: 0.1℃~50℃ (0.1℃~90℃ for hot water meter).

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.
