IC card smart prepaid digital water meter, (can be referred to as: IC card water meter, magnetic water meter, electronic water meter) can be classified to contact smart water meter and non-contact smart water meter, non-contact intelligent water meter, commonly known as: RF card water meter, Card water meter, widely used in the family, apartments, commercial buildings and other household charges of water, hot water use places.
IC card smart prepaid digital water meter product features:
Smart IC card water meter:
1. Using non-contact IC card technology, wireless data transmission is used to solve the problems of waterproof, moisture-proof and anti-attack.
2, micro-power technology: Usually power consumption is less than 0.5μA, so that the battery life greatly increased, to ensure the use of more than 6 years.
3, electric suspension ball valve technology: anti-locking, non-fouling characteristics, can achieve low pressure loss, wear, power consumption, anti-rust, anti-blocking effect.
4, automatic valve discharge, anti-blocking, anti-rust technology: valve timing automatically switch action, the effective use of pipeline pressure caused by the instantaneous impulse of water, to achieve automatic valve discharge, to prevent valve rust die, fouling and other phenomena.
5, full seal design: all lines are all sealed with epoxy resin, good sealing.
6, anti-external, magnetic attack technology: When the external power, magnetic attack, the meter will automatically close the valve.
Working conditions:
Flow range: Q1~Q3 (Q4 short time work not change error)
