NB-IoT valve-controlled water meter is a smart water meter based on NB-IOT narrowband Internet of Things communication technology. It is directly connected to the operator base through wireless transmission, without the need to build a network by itself, and can be directly connected to the public network. The integrated valve at the water meter end can realize remote valve control, and can automatically/remotely control the terminal valve switch action at the set metering value or at an appropriate time, so as to achieve the purpose of remote meter reading and automatic water control, and realize the pre-payment function.

LORA wireless remote water meter, LoRa is one of the current mainstream IoT communication technologies, with advantages such as long communication distance, low power consumption, and self-organizing network. The LORA remote water meter has a built-in self-developed wireless module, which has long-distance communication capabilities in complex environments. The wireless transmission method is connected to the wireless concentrator to realize data collection and meter reading functions. The transmission distance in open areas exceeds 1.2km, and the theoretical distance is 5km.

LORA wireless valve-controlled water meter, built-in LORA wireless communication module, adopts LORA spread spectrum wireless transmission technology, the module can drive the valve to realize automatic control and remote valve switch function. It can automatically/remotely control the terminal valve switch action at the set metering value or at an appropriate time, so as to achieve the purpose of remote meter reading and automatic water control, and facilitate the pre-charge function. The transmission distance in open space exceeds 1.2km, and the theoretical distance is 5km.

Photoelectric direct reading wired remote transmission water meter is based on ordinary water meter with photoelectric direct reading sensor, adopts character wheel scale recognition technology and photoelectric coding principle to read the position of the meter wheel at the moment of meter reading. The electronic part and the mechanical part of the base meter are not in direct contact, which does not affect the metering performance of the base meter. It supports M-Bus/RS-485 wired remote transmission, and can also integrate NB-IOT/LORA wireless communication module to realize remote meter reading.

Photoelectric direct reading wired valve-controlled water meter adopts photoelectric direct reading technology and integrated valves, which can realize remote reading of water meter reading and remote control of valves, effectively solving the problem of door-to-door meter reading and charging difficulties of management departments. It supports M-Bus/RS-485 wired remote transmission, and can also integrate NB-IOT/LORA wireless communication module to realize wireless remote transmission.

The camera-based intelligent reading remote water meter uses a camera to take a picture of the dial, adopts a CMOS image sensor, and is based on an AI intelligent image recognition system to achieve the functions of rapid image processing and high-precision recognition, local data storage, and remote transmission. It enables remote meter reading of water companies, zero transmission error in meter reading data, and image comparison. It is an ideal zero-error metering product in the automatic meter reading system. Direct reading of water meter readings and pictures, with a recognition accuracy of ±0.5 tons and a data accuracy rate of 99.9%.

Small-caliber ultrasonic remote water meter, is a new type of water meter that measures and displays flow based on the ultrasonic transit time  principle. It has an integrated design, beautiful appearance, easy installation, accurate measurement, stable operation, strong anti-fouling and anti-corrosion ability, safety and reliability, etc. It is equipped with an M-BUS interface by default (optional: NB-IOT, LORA), and forms a remote meter reading system through the M-BUS bus and other communication equipment. Valve function is optional.

IC card prepayment water meter (RF card) is a new type of water meter that uses microelectronics technology, sensor technology and contactless RF card technology to measure water consumption, transmit water consumption data and settle transactions. It can automatically control water consumption according to the agreement and automatically complete the calculation of water charges at tiered water prices. Data transmission and transaction settlement are both carried out through IC cards, which can realize the transformation from door-to-door meter reading and charging to users paying at the business office themselves.

IC card plug-in payment water meter (integrated water controller) is composed of base meter, control valve, electronic control module, IC card, etc. It perfectly integrates meter valve and control circuit. Insert the card to discharge water, and remove the card to stop water. When the IC card is inserted into the card reading area of the water controller, the water controller will start the water flow after receiving the information in the card. At the same time, it will automatically deduct fees and time (or measure) water use according to the set rate, and stop when the card is removed. It is widely used in public bathrooms, water rooms, self-service laundromats and other water-using places in schools, enterprises, and government agencies to realize intelligent real-time transactions and settlements.

The Bluetooth prepaid water meter is a smart water meter that can be easily combined with a mobile phone or mobile terminal. It uses Bluetooth wireless communication technology to connect to the mobile phone or applet by scanning the code, and quickly realizes air control or payment. It can measure and electronically display the water consumption, automatically control the water consumption according to the agreement, and automatically complete the calculation of the water fee for the tiered water price. Pay first and then use the water, and the water meter will automatically shut down if the payment is in arrears. Users can pay by themselves through the mobile phone APP.

STS code prepaid water meter, in line with STS standard requirements, uses encrypted 20-bit code as the transmission medium, with high data security, beautiful appearance and easy operation. It integrates LoRa wireless communication module. STS prepaid water meter has the characteristics of balance alarm to prevent arrears, remote keyboard control, cardless recharge, etc.
