Woltman Irrigation Water Meter
The irrigation water meters manufactured by Langhua are designed to meet the demands of agricultural water management. Its magnetic coupling drive and specially treated counting components make it resistant to pollutants while ensuring that readings stay clear and easy to read. Designed for easy maintenance, its removable core makes repairs straightforward. This meter excels in environments with less-than-ideal water quality, such as untreated water sources and irrigation systems, thanks to its robust construction and ability to handle large flows with minimal pressure loss.

Our irrigation water meters are suitable for measuring and monitoring water in agricultural irrigation systems. It helps farmers manage water more efficiently, improving irrigation efficiency, and supporting the sustainability and economic viability of their agricultural practices.
What are irrigation meters?
Irrigation meters are specialized meters designed to measure water used exclusively outdoors. They're typically employed in settings like large orchards, golf courses, or big gardens. Functionally similar to household water meters, they come equipped with a dial that records the volume of water passing through them. This focus on outdoor use makes them an essential tool for managing water in extensive outdoor areas.
Why use irrigation meters?
Irrigation meters are useful in scenarios where watering large areas is required. These irrigation meters are high-flow meters, that can handle various water qualities, making them versatile for different outdoor conditions. A key advantage of using irrigation meters is their ability to measure water that isn't discharged into the sewage system. Consequently, the water passing through these meters isn't subject to wastewater charges, offering an economical solution for large-scale irrigation needs.
