Hebei Shanghong Meters Technology Co., Ltd. is one of the leading manufacturers and suppliers of rs485 ultrasonic water meter in China. If you're going to wholesale high quality rs485 ultrasonic water meter, welcome to get pricelist and quotation from our factory.
The ultrasonic water meter adopts the principle of ultrasonic wave. By detecting the time difference caused by the change of the speed when the ultrasonic sound beam propagates in the water, the water flow rate is calculated by analyzing and processing the water flow rate.
Ultrasonic water meters have the following performance characteristics:
1. High precision: The measurement accuracy is generally within ±1%, and the error is more than 1 times that of mechanical water meter.
2. Low starting point: Ultrasonic water meter can detect tiny water flow, which can help the water supply department to effectively increase income.
3, low pressure loss: ultrasonic water meter has a cross-sectional structure of straight tubular measuring tube, no mechanical parts, reducing water flow barriers, reducing the cost of the water supply department.
Water meter case introduction:
1, the case is made of high quality raw materials, safe and wearable.
2. Use the touch button for easy operation.
3, IP68 level waterproof function.
Our company not only has professional products, but also has a good corporate culture, team building and so on. We believe that companies that help each other can go further and do better.
Working principle
The meter comprises the quality temperature sensor ,the flow sensor and the calculator. The temperature sensor to measure the temperature of water and the flow sensor to measure the volume of water that flow through the pipelines by the transit time difference.
The two data is sent to the calculator after being collected, the consumption water quantity is worked out, stored and indicated on the LCD finally.The main pipe in the water supply pipe, the pipe size is more than DN50.
Work process
1.The ultrasonic water meter collects the flow in the pipeline, and the pressure data is uploaded to thecloud service platform through RTU.
2.Sudden change alarm of pressure and flow.
Software advantages
1.High range ratio ultrasonic water meter, accurate measurement.
2.Fast feedback and accurate positioning of emergency inforrmation.
