The City digital residential GPRS water flow meter developed by sh-meters , the GPRS smart water meter system consists of a GPRS water meter, a SIM card and an operation management platform (web version). A GPRS (2G) SIM card needs to be installed in the water meter. The water meter sends the data to the operating platform through the GPRS network, and the colleague operating platform can also send the switch valve command to the water meter. Managers can monitor the water consumption of water meters anytime, anywhere.
GPRS water meter use conditions:
Water temperature: 0-30℃
Working pressure: no more than 1MPa
Pressure loss class: ΔP63
Maximum allowable error of GPRS water meter:
±5% from low range including minimum flow (qmin) to excluding boundary flow (qt)
From the boundary flow (qt) to the high zone including the overload flow (qs) ± 2%
Power supply: 2.1V-3.6V
Accuracy Class: Class B
Normal Diameter: DN15-DN600
Maximum indication: 999999.9
Flow prefile sensitivity class: U10/D5

Advantages
1. Simple installation, the same installation way as mechanical water meter, without wiring;
2. Without the influence of communication distance, the signal transmission is stable.
3. Sleep is usually carried out, and only when it reaches the online time, it will go online for 30S to ensure the service life of batteries.
Reading Frequency
The reading mode of GPRS water meter system is passive reading. The default reading frequency of water meter is 3 days. Reading frequency 1 time per day is acceptable.
Installation conditions
1. Require high GPRS signal intensity
2. Data reading and water control are carried out every three days.
FAQ
1. What is the battery life?
Regular use of ER26500 battery, 8500mAh, the frequency of meter reading once a day, battery life can be up to 4 years.
2. What is the transmission distance?
In the case of ensuring the GPRS signal strength, the GPRS water meter upload data is not affected by the distance;
Communication
1. Does our platform have a user interface?
At present, there is no user interface in our account. Customer-made software can be used as user interface.
2. What data can the platform collect from water meters?
At present, our platform can collect accumulative flow rate, battery voltage, upload time on the water meter, and ultrasonic LoRa can also collect instantaneous flow rate.
3. Is the platform free? Can it pay in advance?
It is free, and the administrator can pre-charge the amount of money on the platform and set up user information files for each user. But realize the function of prepayment
4.What is needed for system docking
System docking is through HTTP protocol, using web page writing tools, such as POSTMAN, to send our domain name, account, password, command to customers, customers can add these data to their own software, so that customers can read and control water meters through their own software.
