In the modernization process of agricultural irrigation, ultrasonic open channel flow meters, as the core equipment for flow monitoring, are crucial for the long-term stable operation of water resource allocation efficiency and irrigation cost control. However, the special outdoor environment of irrigation channels, such as strong sunlight, temperature difference between day and night, water corrosion, and sediment impact, makes equipment aging and component wear the main factors affecting measurement accuracy.
Equipment aging issues and protective measures
The aging problem of ultrasonic open channel flow meters used in irrigation channels mainly focuses on three aspects: deterioration of shell materials, degradation of electronic component performance, and loss of signal transmission systems.
Protection of structural components
Sensors and instrument boxes directly withstand outdoor environmental impacts. Suggest using weather resistanceABS+PCMade of alloy material, equipped with silicone moisture-proof film and pressure balance valve inside, to control humidity within a safe range. Dalian Yiste Technology has also added a polytetrafluoroethylene protective coating to the sensor probe to reduce algae adhesion and sediment wear.
Electronic system optimization
The aging rate of electronic components is closely related to the operating temperature. During maintenance, it is necessary to ensure good ventilation in the instrument box. For equipment in areas with direct sunlight, sunshades or forced cooling fans can be installed. Devices that adopt intelligent sleep mode can significantly reduce energy consumption, extend battery life, and reduce circuit aging losses.
Signal transmission enhancement
Cable aging and interface corrosion are the main causes of signal attenuation. During maintenance, it is necessary to regularly check the waterproof sealant on the cable sheath and joints. It is recommended to use shielded twisted pair cables and lay them in metal pipes, and regularly apply conductive paste to prevent oxidation of the data interface.
Component replacement cycle and management
The replacement of components does not follow a fixed cycle, and needs to be comprehensively judged based on the water quality, flow rate, and equipment operating load of the irrigation channel.
Core measuring components
Ultrasonic sensors and transducers are the key factors determining measurement accuracy. In ordinary water quality, the benchmark replacement cycle is5-8Year; If the sediment content in the water is high, it is recommended to shorten it to3-5Year. Dalian Yiste Technology provides sensor calibration services to provide accurate basis for replacement decisions.
Auxiliary functional components
For devices powered by solar energy, the battery is a consumable component. Under the illumination conditions in Northeast China, the standard replacement cycle for lead-acid batteries is2-3In the year, lithium batteries can be extended to4-5Year. The replacement cycle of seals is usually2-3If the water in the channel is corrosive, it needs to be shortened to1-2Year.
Electronic control components
The benchmark replacement cycle for the main control motherboard is8-10Year. If the equipment is in a high temperature and high humidity environment for a long time, it is recommended to5Conduct a comprehensive testing once a year.LCDUnder strong outdoor lighting conditions, the display screen usually5-6There will be a decrease in brightness every year.
Full lifecycle guarantee mechanism
Scientific maintenance management needs to combine anti-aging measures with component replacement cycle to form a full life cycle guarantee mechanism. Suggest establishing“routine inspection-Quarterly maintenance-Annual calibration”Establish a three-level management system and establish equipment maintenance files to record information on each inspection, calibration, and component replacement.
With the development of smart irrigation, remote operation and maintenance technology has become an important means to improve maintenance efficiency. The new generation of flow meters from companies such as Dalian Yister Technology have achieved IoT module transmission, allowing operation and maintenance personnel to remotely monitor key parameters, early warning of aging and failure risks, and promoting the transformation of irrigation channel flow monitoring to active guarantee.
