KM02-11
Mbus, GPRS, pulse-based multi-jet water meter
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 a water meter, collector, and management center. It has a direct reading function, no built-in battery, long service life, waterproof, antistatic, moisture-proof, antidust, anti-magnetic interference, optional control valve, and a high waterproof level.
This product is mainly used for water metering in residential areas, commercial buildings, office buildings, industries, etc. with remote meter reading requirements and remote power supply capability.
