RF card water meter

DN15-25mm
is used in situations where tap water users are required to pay first and then use water, changing the measurement method of tap water and pure water meter reading and charging.
Product Features
◆ Using an all-copper integrated rotor wet ball valve base meter and stainless steel ball valve, it has high measurement accuracy, small pressure loss, low power consumption and high reliability

◆ Prepayment charging method, pay first and then use, automatically close the valve without charge, pay Automatic water supply after swiping the card
◆Using high-definition LCD screen display, you can check water purchase information, remaining usable amount of the meter, Accumulated water consumption, meter status and other information
◆The electronic control part adopts a sealed design, which is waterproof, moisture-proof, and anti-magnetic attack
◆When the available water is insufficient, attacked by strong magnetism, or the battery is under-voltage, the system automatically monitors abnormal conditions and the water meter automatically Close the valve to prompt an alarm
◆The whole machine adopts ultra-low power consumption design, and the built-in battery can last up to 6 years
