woltman mechanical water flow meter
Product Description
Application
Measuring the volume of cold (hot) water passing through the pipeline.
water meter is used for home or apartment
Improved crop health: By providing the right amount of water at the right time, a water meter can help maintain healthier crops by preventing over or under watering.
Increased crop yields: Proper irrigation using a water meter can help increase crop yields by ensuring that plants receive the optimal amount of water for growth.
Reduced energy costs: Using a water meter can help reduce energy costs associated with pumping water, as less water is needed when irrigation is precisely controlled.
Compliance with water regulations: Many areas have regulations in place to limit water usage for irrigation. A water meter can help ensure compliance with these regulations by monitoring and controlling water usage.
Reduced soil erosion: By monitoring water usage, a water meter can help prevent soil erosion by avoiding over-watering and excess run-off.

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.
