Recently, the SJ-MQ50 portable open channel flowmeter independently developed by Shandong Water Environment Sensing Technology has been deployed and debugged in multiple large irrigation areas in western Shandong, and officially put into agricultural irrigation flow monitoring work. This batch of equipment, with its precise data collection capability and convenient operation characteristics, effectively solves the problem of "data lag and large measurement errors" in traditional irrigation monitoring, providing a scientific basis for water-saving irrigation.
The SJ-MQ50 portable open channel flowmeter put into use this time is the core product of water environment sensing technology optimized and upgraded for agricultural irrigation scenarios. According to the project technical leader, the equipment adopts the principle of ultrasonic non-contact measurement, which does not require direct contact with the water body, and can avoid the corrosion of the sensor caused by sedimentation and pesticide residues. It can still maintain stable performance in the complex water quality environment during the peak irrigation season. Its liquid level measurement accuracy reaches ± 3mm, and the flow calculation error is controlled at an excellent level in the industry. It supports automatic recording of a set of data every 10 minutes and stores 144 sets of effective information per day, meeting the needs of refined management in irrigation areas.
Previously, the flow rate was estimated manually, and watering was either too much or too little. Now, with this equipment, the average water consumption per mu can be accurately controlled. "A manager from a certain irrigation district showed actual test data: after deploying the equipment, the irrigation water efficiency increased by 30%, and the monthly water saving in a single irrigation district exceeded 20000 cubic meters. The portability of the device has also been recognized by frontline personnel, with a total weight of 6.6kg and a configuration of 700200The 130mm folding tripod can quickly move and measure different irrigation channel sections, and the data can be exported via USB to directly generate analysis reports, greatly reducing labor costs.
The Market Director of Water Environment Sensing Technology stated that this portable open channel flowmeter has passed the HJ15-2019 "Technical Requirements and Testing Methods for Ultrasonic Open Channel Sewage Flowmeters" certification. In addition to agricultural irrigation, it is also widely used in environmental pollution monitoring, hydrological survey and other fields. In the future, the company will continue to optimize its products based on user feedback, helping to transform water resource management towards digitization and precision.
