Monitor water levels in irrigation channels and dams with this SDI-12 submersible level sensor. 10m range, low power consumption, and durable construction for long-term deployment in harsh environments.
This S12S submersible level sensor is ideal for long-term deployment in irrigation channels and storage dams, providing accurate and reliable water level measurements even in harsh conditions. Its robust construction, featuring a stainless steel 316L housing and Viton seals, ensures compatibility with a wide range of water qualities, including those with high mineral content or the presence of fertilizers and other agricultural chemicals.
The inclusion of a protective nose cone not only safeguards the sensor diaphragm from potential impact damage during installation and retrieval but also enhances accuracy by preventing the formation of air pockets or vortices that can disrupt pressure readings. This is particularly crucial in dynamic environments such as irrigation channels where water flow can vary significantly.
The sensor’s SDI-12 digital interface offers several advantages for remote monitoring applications. This standardized protocol allows for efficient data transmission with low power consumption, making it ideal for battery-powered telemetry systems often used in agricultural settings. Additionally, the SDI-12 interface enables multi-drop configurations, where multiple sensors can be connected to a single telemetry unit, reducing installation costs and complexity for large-scale irrigation networks.
For integration with existing infrastructure, the S12S is equipped with a G1/4 male DIN3852 process connection, a standard fitting in many irrigation systems. This ensures compatibility with a wide range of mounting adapters and accessories, simplifying installation and maintenance procedures.
The sensor’s 15-meter PUR cable provides ample length for most irrigation channel and dam applications, while its robust construction withstands the rigors of submersion, UV exposure, and potential abrasion from surrounding vegetation or debris.
By providing precise water level data, the S12S enables efficient water resource management in agriculture. This data can be used to automate irrigation schedules, optimize water distribution, and prevent overfilling or draining of storage dams, contributing to sustainable water use practices and maximizing crop yields.
