Product use
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 pipeline, and the temperature sensor measures the temperature signal at the inlet. After the calculator collects the above signals, it integrates and processes them, and displays the water flow rate through the water meter for a period of time on the LCD display.
Product Features
Product features
The temperature sensor uses Pt1000 platinum resistance paired with a high-precision AD circuit to achieve high-precision temperature measurement
The flow sensor of this meter measures accurately, and the housing is made of copper shell. It has been forged by hard mold, processed by CNC machine tool and combination machine tool, with good mechanical strength and high dimensional accuracy
The MCU adopts the MSP430 series ultra-low power microprocessor from TI in the United States, which has strong functions, low power consumption, and strong electromagnetic interference resistance,Equipped with power shortage alarm function
Adopting LCD display, displaying complete and accurate data, and reading data conveniently and quickly. Real time clock design to achieve date recording and display functions
Adopting environmentally friendly lithium batteries with a lifespan of over 6 years (theoretically calculated to be greater than 10 years)
Integrated structure, beautiful appearance, display can rotate horizontally and flip vertically, easy to read; Single key design, easy to operate, display screen rotates 360 degrees horizontally and 180 degrees vertically, convenient for installation
Using GP21 measurement chip produced by German ACAM company, the data is accurate and stable
Complete interfaces, expandable MBUS bus interface, RS485 bus interface, and infrared interface, enabling remote data collection and centralized control
Easy to install and maintain, with functions such as dust-proof, moisture-proof, waterproof, anti disassembly, and preventing human damage
