Sewage And Irrigation Type Water Meter
The irrigation water meter is specially designed for the irrigation system to provide the most accurate and reliable flow reading. Due to its special structure different from ordinary water meters, its circulation capacity is far greater than that of ordinary water meters.
Product Features:
♦ Low transmission resistance, large circulation capacity♦ Strong anti pollution ability
♦ Dry magnetic drive, anti condensation atomization, clear reading
♦ Stable and durable
