Soil monitoring equipment: tubular soil moisture meter

A tubular soil moisture meter is a soil moisture metering device based on the FDR (Frequency Domain Reflectometry) principle. It usually consists of a long tubular probe that can be inserted into the soil to make measurements. It determines soil moisture by sending electromagnetic waves and measuring the change in frequency of propagation of these waves in substances with different dielectric constants. The device is also equipped with a high-precision digital temperature sensor to measure the temperature of different soil layers. At default settings, it is capable of simultaneously metering moisture and temperature in the 10cm, 20cm, 30cm and 40cm soil layers to suit the metering needs of different crops and soil types. It is suitable for long-term metering of representative soils.

The instrument consists of a precision soil moisture sensor, soil temperature sensor, solar power supply and transmission device, and is widely used in agriculture, forestry, environmental protection, water conservancy, meteorology and other industries. It is also suitable for water-saving irrigation, flower horticulture, grass pasture, soil quick test, plant culture, greenhouse control, fine agriculture and other fields to meet the needs of scientific research, production, teaching and other aspects.

Tubular soil moisture meter product features include:

1. With the ability to measure moisture and temperature changes in real time at multiple depths, the standard nodes are 10cm, 20cm, 30cm, 40cm depth, and can also be customised to measure at greater depths, up to 100cm.

2. Using special customised PVC plastic pipe with anti-aging and corrosion resistance, it is able to resist the erosion of acids, alkalis and salts in the soil.

3. Epoxy resin is used as sealing material, no leakage will occur even if the equipment is immersed in water for a long time.

4. High measuring accuracy, reliable performance, little influence by soil type, suitable for all kinds of soil.

5. Power, ground and signal lines with multi-directional anti-wrong connection protection.

6. Support RS485 digital output and GPRS wireless network data transmission (optional).

7. Provide a variety of power supply options, including DC12~24V DC power supply and solar power supply.

8. Designed for site-free setup and calibration, it is very easy to install and use.

9. It is also lightweight, easy to install, easy to use and accurate in measurement.

The advantages of using a tube soil moisture detector include:

1. Accuracy: This device can provide very accurate soil moisture readings, helping farmers or agricultural scientists to better understand soil moisture conditions.

2. Repeatability: Tube devices can be recalibrated and reused to ensure long-term metering accuracy.

3. Adjustable depth: The depth of the sensor can be adjusted according to the water demand depth of different crops.

4. Real-time metering: connected with the data reading system, it can realise real-time metering of soil moisture and provide timely feedback on soil moisture changes.

5. Strong adaptability: suitable for various sizes of farmland and different soil types and structures.

However, it should be noted that tube soil moisture detectors are usually costly and require some technical support for installation and maintenance. It is also important to interpret the data correctly, taking into account the specific soil type, crop water requirements and other environmental factors for effective irrigation and water management.

Tubular soil moisture detector application scenarios:

Agricultural irrigation management in arid areas

In arid areas where water resources are scarce, the rational use of irrigation water is critical to agricultural production. The Tube Soil Moisture meter can be used in such areas to help farmers or irrigation managers meter soil moisture conditions to optimise irrigation strategies and save water.

With the tube soil moisture meter, the humidity and temperature of different soil layers can be metered in real time to understand the soil moisture status. Based on the metering data, irrigation managers can make targeted irrigation plans to avoid over- or under-irrigation and ensure that crops receive the right amount of water.

In addition, tubular soil moisture meters can be used in conjunction with intelligent irrigation systems to achieve automated irrigation control. When the soil moisture falls below a preset threshold, the meter will automatically send a signal to the smart irrigation system to activate the irrigation facilities for water replenishment. At the same time, the meter can also transmit data to the cloud via wireless network to achieve remote metering and management, further improving the intelligent level of irrigation management.

In the agricultural irrigation management in arid areas, the application of tube soil moisture meter helps to improve the efficiency of water resources, ensure the stability of agricultural production, and promote the development of sustainable agriculture.

Intelligent greenhouse planting

In the field of smart greenhouse planting, tubular soil moisture meter can play an important role. Plant growth in smart greenhouses requires precise control of soil moisture, temperature and other environmental factors to ensure healthy plant growth. Tubular soil moisture meters can be deployed in smart greenhouses to meter the moisture and temperature of different soil layers in real time, providing key data for the greenhouse control system.

By metering soil moisture and temperature in real time, the greenhouse control system can automatically adjust facilities such as irrigation, ventilation, heating and cooling according to the plant's growth needs, keeping the soil moisture within the appropriate range to ensure that the plant receives a favourable growing environment. At the same time, the meter can also transmit data to the cloud via wireless network, realising remote metering and management, and improving the intelligent level of greenhouse cultivation.

In addition, the tube-type soil moisture meter can also provide rich data support for researchers to help them study the soil moisture and temperature requirements of different plants, providing important references for optimising planting plans and improving crop yields. In the field of intelligent greenhouse planting, the application of tube-type soil moisture meter can help to realise efficient and precise agricultural production and improve agricultural output.

 In conclusion, tube-type soil moisture meter plays a very important role in agricultural production, which can help farmers manage soil moisture scientifically and avoid losses caused by excessive irrigation or drought. Meanwhile, it is also widely used in scientific research and environmental metering to provide data support for the study of soil moisture condition.
