Design & Functionality
The HLM-25S is built around a compact submersible probe containing a pressure sensor and integrated signal electronics. When submerged in liquid, the sensor measures hydrostatic pressure generated by the liquid column above the probe. This pressure is then converted into a precise electrical signal proportional to the liquid level.
The stainless steel probe housing protects the internal sensing elements while ensuring corrosion resistance and mechanical durability. A specially designed cable with an integrated capillary tube compensates for atmospheric pressure changes, ensuring stable and reliable measurements over time.
Total Crossed Beams
The sensing mechanism inside the probe ensures precise pressure detection through a balanced sensor design that minimizes mechanical stress and improves measurement stability. This configuration allows the instrument to maintain consistent performance even during long-term submersion in water reservoirs and monitoring systems.
Beam Pitch Options
The device supports customizable measurement ranges, allowing system integrators to configure the sensor according to the required depth measurement. This flexibility makes the instrument suitable for shallow tanks, deep wells, groundwater monitoring systems, and environmental water management applications.
Intrinsic Synchronism
Advanced electronic processing ensures stable signal transmission and precise level calculation. The sensor maintains accurate output signals even during temperature variations or long-term deployment in submerged environments.
Operational Advantages
Industrial users benefit from the HLM-25S due to its robust design, high measurement accuracy, and easy installation. The sensor can be directly suspended in the liquid using its cable, eliminating the need for complex mounting hardware.
Its durable stainless-steel construction ensures long service life, while IP68 protection allows safe operation in permanently submerged conditions. These characteristics make it a reliable choice for water treatment plants, groundwater monitoring systems, reservoirs, and industrial liquid storage applications.
