Features
Our instruments boast a remarkable blend of safety, cleanliness, precision, longevity, stability, and reliability. They are designed for effortless installation and maintenance, suitable for challenging environments such as acidic, alkaline, saline, antiseptic, and high temperatures. Seamlessly connect to display meters, PLCs, and various DCS systems using a 4~20mA interface, delivering real-time liquid level data crucial for industrial automation. Crafted with premium power components and imported, highly reliable devices, our instruments stand as superior alternatives to foreign counterparts. Equipped with acoustic intelligent technology, they perform dynamic echo analysis without intricate debugging, achieving impressive accuracy with a liquid level precision of ±0.25%, all while resisting interference waves. These non-contact instruments minimize failure rates, offering diverse installation methods and comprehensive calibration through the manual. Each instrument is fortified with lightning and short-circuit protection across all input and output lines, ensuring unparalleled durability.

Installation Guide

In open environments, the bracket installation method is typically employed, with the instrument secured using a spiral ring. Alternatively, you may opt to create a circular aperture, 60 mm in diameter, at the installation site on the tank top or lid, then position the meter within and secure it by tightening the screw ring from beneath. Crucially, ensure the probe surface aligns with the liquid surface to ensure precise measurement. As the probe interacts with the liquid, it reflects waves back to the probe, which calculates the elapsed time to determine the measurement space H. Subtracting H from the installation height TH reveals the current level L. Ensure the TH is less than the measurement range, while the highest liquid level should surpass the blind zone, which is the region near the probe that the meter cannot measure. For instance, with a blind zone of 0.5m, ensure the liquid level remains above this threshold. If the measuring range is 6 meters and the blind zone is 0.45 meters, the maximum measurable liquid level spans 0 to 5.55 meters. Be mindful of wave propagation during installation to avoid collisions with pool walls or channel edges.
