KM02-10
This series of products adopt a photoelectric direct reading module to read the water consumption data and upload it through a special wire. The whole system consists of the water meter, collector, and management center. Direct reading function, no built-in battery, long service life, waterproof, anti-static, moisture-proof, anti-dust, anti-magnetic interference, optional control valve, high waterproof level.
