Introduction
The water meter consists of a non-magnetic or ultrasonic flow sensor, a single temperature sensor and a calculator. The flow sensor measures the volume of water flowing through the pipe, and the temperature sensor measures the temperature signal of the water inlet. After the calculator collects the above signals, it integrates and processes them, and the LCD displays the water flow rate flowing through the water meter over a period of time.
Product features
1. Built-in high-precision flow sensor, the shell is copper shell, high dimensional accuracy.
2. The temperature sensor is a Pt1000 platinum resistance paired temperature sensor, equipped with a high-precision AD circuit to achieve high-precision temperature measurement.
3. For MCU, the MSP430 series ultra-low power microprocessor of TI Company of the United States is selected, which has powerful functions, low power consumption and strong anti-electromagnetic interference ability.
4. Power shortage alarm function.
5. The LCD display shows complete and accurate data, and it is convenient and fast to read data. Real-time clock design and date recording.
6. Built-in environmentally friendly lithium battery, with a service life of more than 6 years (theoretical calculation is greater than 10 years).
7. Integrated structure, the display can be rotated horizontally and flipped vertically, and reading is convenient. Single-button design, easy operation, the display screen rotates 360 degrees horizontally and 180 degrees vertically, which is easy to install.
8. Using GP21 metering chip produced by ACAM Company of Germany, the data is accurate and stable.
9. Complete interfaces, expandable M-BUS bus interface, RS485 bus interface and infrared interface, realize remote data collection and centralized control.
10. Easy to install and maintain, with dustproof, moisture-proof, waterproof, anti-disassembly, anti-human damage and other functions.
