Overview:
The prepayment hot water meter takes propeller type water meter as the base, moreover provided with reed switch mail-getting device, low power-consumption electrical control valve, micro-computer control system and smart card information system. It changes the traditional water charging method, from “charge follows water” to “water follows charge”. Detailed record is presented for every water-charging operation, which thoroughly removes the two issues in water charge management of “Difficult charge operation, chaotic accounts”. The prepayment water meter with remote reading function can also make statistic of water volume in real time, so as to provide accurate evidence for settlement of water charge. The product satisfies all technical requirements in National Standard GB/T778-2007 Measurement on Water Flow in Enclosed Pipelines, Cold Drinking Water and Hot Water Meter and Industrial Standard CJ/T133-2012 IC-card Hot Water Meter.

Features:

• Accurate metering: Use high-strength material inter-machine which has low starting flow and high metering accuracy.
• Prepayment function: Water follows charge. The valve automatically shuts down without charge, and automatically starts after charging.
• Water sales record and filing: Each water sales operation is recorded, with clear accounts which cannot be modified at will, and multiple statistic statements are presented for searching.
• One-card function: If the same user has installed the two or more water meters or the water meter, electrical energy meter and gas meters at same time, all smart meters can share one card, convenient for user.
• Display function: With high-definition LCD, it can directly read the water volume, remaining water volume, accumulated water volume, valve state, battery state and other data.
• Alarm function: When the remaining water volume reaches or is lower than the alarm setting value, the water meter automatically shuts down for one time, to inform the user for purchase, and the user can open the valve to consume water yet by swiping card, and the valve will thoroughly shuts down when remaining water is 0.
• Rust resistance function: Water meter valve automatically opens and closes at a regular time interval, in order to avoid rust of valve.
• Attack-proof function: When the water meter is attacked by strong magnetism, the water meter automatically shuts down, and records the attack information, which can be opened only after the external interference is removed.
• Low power-consumption design: Whole control circuit is designed with low power consumption, having the small static current and the service life of battery more than 6 years.
• Water-proof design: Each key parts are treated with multiple water protection, having great water resistance performance.
• Ladder water price function: Single water price program and ladder water price program are alternatively presented.
