Doppler Flow Meter Applied in Sewer Pipelines to Detect Sewage Discharge Volume [Dayu Electronics]

In recent years, with the continuous increase of urban permanent residents, major cities have developed rapidly and continuously expanded outward. This has been accompanied by the renovation of urban drainage systems. The design and construction of urban drainage systems have always been a major challenge since ancient times, which inevitably brings up the ultrasonic Doppler flow meter.

The ultrasonic Doppler flow meter is applied in the sewer pipelines of Jiande County, Yancheng City, Jiangsu Province, to detect sewage discharge volume. The on-site customer reported that despite water depth being present, the flow display was intermittent. When the technician arrived on site and connected a computer to monitor the instrument, they found low signal strength. Upon lifting the probe, they found it was covered with debris. After cleaning the debris, the data returned to normal.

Ultrasonic Doppler flow meter What are the installation requirements in pipelines? Many users often encounter various problems when installing Doppler flow meters in pipelines, resulting in deviations in measurement data.

Installation requirements:

1. If installed inside a pipeline, it must not be installed at the very bottom of the pipe. Because the bottom typically has sediment or sludge carried by the water flow. Sludge can affect the measurement, weakening the measurement signal or causing data fluctuations.

2. The water flow must cover at least 5 cm above the top of the sensor for the measurement data to be close to the actual flow velocity.

3. The sensor head must not be directed at the pipe wall or well wall, otherwise the measurement data will have large deviations.

Product features:

1. Designed for flow measurement in open channels, channels, or partially filled pipes; supports both partially filled and full pipe flow measurement;

2. Can measure extremely low flow velocities, as low as 0.03m/s;

3. Can measure bidirectional flow;

4. Optional built-in GPRS remote transmission function module;

5. Built-in ultra-large capacity storage function, with customizable data storage intervals;

6. UPS power-off protection, can be powered by solar energy (optional);

7. Can connect to computers and mobile phones for real-time monitoring of flow field velocity distribution.
