Sewer Ultrasonic Flow Meter Case in Urumqi, Xinjiang [Dayu Electronics]
The ultrasonic pipe network flow monitor is a flow monitoring device designed with integrated sensor technology. It features low power consumption and is powered by a built-in, quickly replaceable, high-capacity, long-endurance lithium thionyl chloride battery pack. It is suitable for urban drainage pipe network flow monitoring, urban outfall pipe flow monitoring, canal flow monitoring, and culvert flow monitoring. The Doppler flow monitor uses NB-IoT communication to transmit data remotely to the flow monitoring system platform, enabling functions such as drainage pipe network flow monitoring, data alarm processing, and statistical analysis.
Features:
This ultrasonic sewer flow meter is manufactured by our company and offers high measurement accuracy and a wide range, capable of measuring both weak and strong flows. It has low power consumption of 70-90mA/12VDC. This flow meter operates on the Doppler effect principle and is suitable for flow measurement of two-phase media containing a certain amount of solid particles or bubbles that reflect sound waves.
Advantages:
Suitable for large pipes: Insertion-type ultrasonic flow meters are particularly suitable for pipes with large diameters, where traditional flow meters such as electromagnetic flow meters may not be applicable due to size and cost constraints.
Easy maintenance: Since the probes can be maintained and calibrated from outside the pipe, maintenance work is relatively easy.
Wide adaptability: Ultrasonic flow meters can be used to measure a variety of clean and dirty fluids, including corrosive, viscous, or fluids containing suspended solids.
Long-term stability: Ultrasonic flow meters offer good measurement stability, and accuracy does not degrade significantly after long-term operation.
Application areas: Wastewater treatment plants, industrial process control, oil and gas industry, chemical industry, and drinking water supply systems.
Installation steps:
Regarding the installation site of the ultrasonic low-power manhole flow meter in Xinjiang, the following are some key installation steps and precautions:
Understand the site conditions: Before installation, the site conditions should be thoroughly understood, including pipe material, wall thickness, pipe diameter, pipe age, fluid type, fluid temperature, and whether there are interference sources at the installation site.
1. Installation preparation: First, necessary materials such as sensor cables and coupling compound should be prepared. Also, ensure that installation tools such as impact drills are available.
2. Select the installation location: Choosing the appropriate installation location is crucial. Avoid interference and vortices, and select a pipe section with uniform and dense material that is easy for ultrasonic transmission. In addition, the upstream straight pipe section should be greater than 10D, and the downstream should be greater than 5D. Install the sensor: When installing the sensor, ensure it is tightly attached to the pipe wall, and apply sufficient coupling compound between the sensor and the pipe wall to prevent air, dust, and rust from entering and affecting the ultrasonic signal transmission.
3. Commissioning and settings: After installation, perform commissioning and parameter settings. This includes setting parameters such as pipe outer diameter, pipe wall thickness, and fluid type. During commissioning, ensure that the signal strength and transmission time ratio meet the requirements.
4. Installation space requirements: For installations in meter manholes, ensure there is sufficient installation space for personnel to work upright. The distance between the pipe wall and the wall should be at least 550mm.
5. Precautions: During installation, pay attention to grounding the host housing, and avoid installing sensors at flanges, welds, or diameter changes.
Environmental description: Xinjiang is the most water-scarce region in China and also has the most developed water conservancy pipe network. This product is installed in the Urumqi Water Conservancy and Municipal Water Supply Pipe Network in Xinjiang, used for monitoring drainage network flow. After on-site guidance and installation testing, it perfectly solved the water flow measurement problem, achieving real-time monitoring and IoT-based water flow management.
