LXSGY photoelectric direct reading water meter

1. Product overview Photoelectric direct reading water meter is a kind of water meter that uses photoelectric direct reading

technology to read the data of the word wheel. It has no error in reading and strong anti-interference ability. It is

designed with low power consumption and uses M-BUS to copy the water consumption.

2. Product features ● By using the unique direct reading coding technology, the position state of the counter wheel is read directly at the moment of meter reading, and then it is transmitted to the system background after decoding, and the same value as the water meter window is displayed on the meter reading interface. Free from the influence of time, environment and backflow, and truly achieve zero error. ● Power supply is not needed at daily life, but only at the moment of meter reading, and the service lifetime is long. ● There is no physical contact between the direct reading sensor and devices such as counters, which does not affect the metering accuracy. ● EMC test meets the requirements of national standards, and overcomes the problem that the accuracy and stability of direct reading water meters are affected by external electromagnetic interference. ● Unique address code: each meter has a unique address code belonging to this table, which is convenient for management and maintenance. ● Error protection: there are error protection devices for bus open circuit, short circuit and idle.

LXSK IC card prepaid water meter

1. Product overview IC card smart water meter is based on the original ordinary mechanical water meter with prepaid function. The

meter adopts microprocessor control technology for data acquisition and processing, LCD display, IC card medium

for data exchange, and micro-motor to control valve switch.

2. Product features ● The design service time of lithium battery power supply can reach to ≥6 years. ● One card and one key cannot be copied. ● When the battery is dead or replaced, the valve will be automatically closed, effectively preventing water theft.

When the battery is dead, the IC card will automatically open the valve when it contacts the sensing area of the

water meter, which will not affect the user's water use. ● The whole meter can be sprayed waterproof, that is, when the water meter shell is drenched with water (the time is not more than 24 hours), the work of the water meter will not be affected. ● When a magnetic object approaches the water meter, the water meter will automatically close the valve to prevent

the magnetic object from interfering with the metering of the water meter.
