Woltman Water Meter Compound Pulse Output Agriculture DN300
Product Description
"Irrigate water meter" refers to a type of water meter used to measure water usage in irrigation systems. It is designed to accurately measure the flow rate and volume of water used for irrigating crops or landscaping, and is typically installed on the main pipeline of an irrigation system.
Irrigate water meters can help farmers and landscapers monitor their water usage and make informed decisions about irrigation practices. By measuring the amount of water used, they can optimize irrigation schedules and prevent over watering, which can save water and reduce costs.
Some common features of irrigate water meters include accuracy, durability, and resistance to corrosion and tampering. They may also be designed to resist clogging by dirt and debris commonly found in irrigation water.
Overall, irrigate water meters are an important tool for efficient and sustainable water management in agriculture and landscaping.

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.
