How are liquid flow sensors used in agricultural irrigation?

Status of agricultural development

Nowadays, there are three main categories of agricultural water-saving technologies. The first category is the rational development, collection and optimal utilization of water resources, such as the application of rainwater collection technology, well and canal combination complementary technology and water storage irrigation technology in the development and optimal utilization of agricultural water resources.

The second category is the utilization of grey water recovery and recycling technology, such as poor quality water utilization technology and irrigation return water utilization technology. The third category is the technology that realizes water conservation through various engineering techniques and management methods in the process of water use. Such as channel seepage control, sprinkler irrigation technology, drip irrigation technology, biological water conservation measures, and graded water pricing system.

Against the background of the rapid development of agriculture and the strategic deployment of water conservancy to develop the country, water-saving agricultural technologies in various countries have also developed rapidly, especially in water-saving irrigation engineering technologies and agronomic supporting technologies. Great progress has been made in the application and popularization of new technologies. The popularization has made breakthroughs and promoted food growth.

Problems in agriculture

However, agricultural irrigation is still facing many problems such as high investment costs for irrigation projects and lack of water-saving programs. Promoting agricultural water conservation and the healthy development of water conservation will be conducive to the sustainable development of agricultural water resources in all countries.

Introduction to Liquid Flow Sensors

The flow sensor is one of the most critical components of a flow meter. It constitutes the flow meter and device together with signal processing components, data transmission and communication components. Flow meters play a very important role in energy metering, industrial and agricultural production process parameter measurement, environmental engineering testing and scientific experiments. They are also one of the main instruments in process automation instruments and devices.

Water flow sensors are rarely used alone. Most of them are applied in various types of water meters, heat meters, water flow meters and other products to sense and convert the flow or flow rate of media in closed pipelines. From the perspective of market application, in addition to drinking water measurement, agricultural irrigation measurement, sewage measurement, domestic hot water measurement, heating hot water measurement, fire water measurement and other needs are also expanding.

From the perspective of the application of new technologies for water flow sensors, flow sensing and signal processing technology, micro-power design technology, etc. have been widely emphasized and applied, making an important contribution to the improvement of the measurement accuracy of the flow sensors, the expansion of the measurement range, the reliability of the measurement and the service life of the guarantee.

3 Ways to Control Water Volume with Liquid Flow Sensor

1. Drip irrigation system: Drip irrigation system is an irrigation system in which water is piped near the roots of a crop and then dripped through a drip line to the roots of the crop. Liquid flow sensors can be used to control the flow of water from the drip heads to ensure a consistent flow of water from each drip head, thus ensuring an even supply of water to the crop.

2. Sprinkler system: Sprinkler system is an irrigation system that sprays water onto crops through sprinkler heads. Liquid flow sensors can be used to control the flow of water from the sprinkler heads to ensure a consistent flow of water from each sprinkler head to ensure an even supply of water to the crops.

3. Spring Irrigation System: A spring irrigation system is an irrigation system in which water is piped into the soil and then sprayed onto the roots of the crop by pressure. Liquid flow sensors can be used to control the flow of water through the pipes to ensure a consistent flow of water, thus ensuring an even water supply to the crops.

Application effects of liquid flow sensors

1. Water saving: Liquid flow sensors can control the switching of the irrigation system by measuring the water flow to avoid unnecessary waste. At the same time, through the sensor to measure the flow and automatically adjust the intensity of spraying, can also avoid excessive spraying and dripping, so as to realize more effective irrigation and reduce the use of water.

2. Fertilizer saving: The liquid flow sensor monitors whether the sprinkler system is functioning properly. When the system fails, the sensor can send out timely alarms. This helps to identify and solve problems in the irrigation system in time, avoiding fertilizer loss and waste due to system failure.

3. Improve irrigation efficiency: Liquid flow sensors can monitor and control the operation status of the irrigation system in real time to ensure that the sprinkler system operates under optimal conditions, thus improving irrigation efficiency.

4. Optimize the proportion of water and fertilizer: Liquid flow sensors can be used in conjunction with intelligent irrigation systems to automatically adjust the proportion of water and fertilizer according to the needs of plants and soil conditions to achieve precise irrigation and precise fertilization, thereby improving crop yield and quality.

5. Reduce agricultural costs: the application of liquid flow sensors can reduce the cost of agricultural irrigation and fertilization, reduce waste and unnecessary resource consumption.

In summary, the liquid flow sensor in the agricultural irrigation system has a significant water and fertilizer saving application effect, which helps to improve agricultural production efficiency, reduce agricultural costs, and promote the sustainable development of agriculture.
