1. Installation requirements and precautions for sewage flow meters
2. Correct handling methods for sewage flow meters when there is no signal
Correct handling methods for sewage flow meters when there is no signal: When the sewage flow meter has no signal, the following effective measures can be taken for troubleshooting and handling: adjusting the probe position: Reason: dirt inside the pipeline may hinder the reflection of ultrasonic waves, causing the sewage flow meter to miss the signal. Solution: Gently and slowly move the probe next to the installation point to find the location with the strongest signal. This method can effectively prevent the accumulation of dirt in the channel from affecting signal reception. Illustration: Note: The illustration shows the adjustment of the probe, which needs to be adjusted according to the actual situation on site during operation. Check and optimize probe assembly: Reason: The assembly position and method of the probe may affect signal reception. Solution: Check if the probe is too close to the inside of the pipeline and if the probe is correctly installed on the long diameter of the pipeline. If a horizontal installation method is used, there is usually no need to install additional probes. When installing the probe, it is recommended to use the Z-method for installation to improve the signal reception effect. Use adhesive and check the liquid inside the pipeline: Reason: The state of the liquid inside the pipeline (such as water and other liquids) has a significant impact on measurement and sampling, which may lead to signal attenuation. Solution: Apply adhesive onto the probe to simplify the installation process and improve measurement accuracy. Check for water or other liquids in the pipeline to ensure sufficient signal strength during measurement and sampling. Gently polish the sealed part of the pipeline with gauze to ensure good contact and sealing. Check for internal cracks and dirt in the pipeline: Reason: Internal cracks in the pipeline may cause signal loss, while excessive dirt may hinder signal transmission. Solution: Carefully inspect whether there are cracks inside the pipeline, and if found, repair them in a timely manner. If there are too many internal organs in the pipeline, you can try gently tapping or shaking the pipeline (be careful not to apply too much force) to remove dirt. Comprehensive investigation and contact with professionals: After conducting the above investigation and handling, if the problem is still not resolved, it is recommended to conduct a comprehensive investigation of the entire measurement system, including power supplies, cables, converters, and other components that may affect signal transmission. If the problem still cannot be solved, it is recommended to contact the manufacturer or professional maintenance personnel of the sewage flowmeter for further technical support and assistance. Through the above steps, the problem of no signal from the sewage flowmeter can be effectively solved, ensuring the normal operation of the measurement system and the accuracy of the measurement data.
