DN300 Removable Large Caliber Turbine Irrigate Water Meter
Product Description
Application
Measuring the volume of cold (hot) water passing through the pipeline.
water meter is used for home or apartment
The application of a water meter in irrigation systems can help monitor water usage and ensure efficient irrigation practices. By measuring the amount of water used for irrigation, the water meter can provide valuable information about when to water and how much to water, allowing for more precise and effective irrigation. This can result in water and cost savings, as well as improved plant growth and yields.

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.
