Product details
Prepaid heat meter (large caliber IC card hot water meter)
Product Overview:
Smart IC card water meter is a new type of water meter that uses modern microelectronics technology, modern sensing technology, and smart IC card technology to achieve water quantity measurement, water use control, data transmission, and transaction settlement. This meter is used to measure the flow rate of cold/hot water in pipelines. The product complies with GB/T778-2007 and CJ/T133-2012 product standards. Yidu IC card water meters can be divided into contact and non-contact series water meters. Contact type water meters can be divided into logic encryption cards and CPI cards based on the card medium, while non-contact type water meters are RF cards. Its application has completely changed the traditional household meter reading mode in the past, realizing the water use mode of payment before water supply, greatly facilitating the water supply management department and users.
Applicable scope:
IC cards and RF intelligent large-diameter water meters should be mainly suitable for villa areas, underground water meter wells, and large merchants.
1. Main functions and features
© The card insertion and display part can be separated from the water meter, allowing operators to operate remotely without going down the well, while using precision components to stay away from harsh underground environments
© Modular design: capable of online maintenance and repair. No need to dismantle the meter, and the components are modular, only the damaged parts need to be replaced.
© Module sealing: Even if the water meter well is flooded with water and the water meter is submerged for a short period of time, it can still work normally.
© No need for AC power supply, using industrial batteries for easy battery replacement.
© Users pay before using water
© Ultra low power consumption design extends the lifespan of water meters
© Magnetic attack, two-stage valve closure due to battery undervoltage, and Chinese character warning information when the remaining water level is lower than the set water level
© Split type handheld device with LCD display, allowing users to check the accumulated water usage and remaining water in the table at any time
© Unique interactive authentication between table cards ensures system security
