Product Introduction
IC card prepaid cold water meter is a new product developed by our factory. It is based on the original water meter through the sensor for data collection, dedicated CPU to do the corresponding data processing, display and control the valve action, to achieve the purpose of presale the amount of water to pay for water. It uses a dedicated lithium battery, a unique bayonet anti-attack circuit, advanced hardware and software processing, safe and reliable IC card dynamic encryption mechanism, making the whole table performance safe and reliable, with high precision, low power consumption, small size, easy to install and other objects.
functions and features
★Automatically close the valve when the pre-charged water fee is used up.
★Remind to purchase water. When the remaining water volume is less than or equal to the alarm water volume, an alarm signal will be issued (close the valve and the card can be restored at this time). The value of the alarm water volume can be flexibly set before leaving the factory according to the actual needs of users.
★Reliable valve action
★With error code prompt function
★With mechanical meter and LCD dual display.
★Accurate measurement, regardless of the forward and reverse flow of water can be accurately measured
★Fault tolerance is very strong, even if the reed switch is damaged all the way, the valve in place switch damage can also work normally.
★Advanced digital anti-jamming circuit, unique anti-crash circuit and a number of fault-tolerant design, safe and reliable operation
★Reliable data communication ensures that data will never be lost or garbled.
★Low power consumption design, built-in lithium battery can be used for more than 5 years
★Support all-in-one card function, can share a card with the meter to sell electricity and water management
★With anti-magnetic function and undervoltage prompt function
★Power supply: lithium battery
