➤ Product Introduction
In the measurement of swimming pool/drift samples, strong light refraction caused by moving bubbles or elongated surfaces in the water sample is the main source of measurement error. Measurement data becomes unstable with bubble variations, and turbulence brings changes in turbidity and suspended solids. This defoaming detection application device provides an indoor/outdoor flow-through measurement solution for optical turbidity detection sensors in environmental monitoring scenarios.
Based on the principle of specific gravity, when viscous sludge-laden water samples enter the measurement tube, bubbles quickly rise and escape. The water sample flows through the optical detection zone at a uniform rate, providing the optical sensor with a nearly ideal stable measurement environment featuring constant pressure, steady flow, light shielding, and defoaming.
➤ Main Performance Features
● Water-air separation eliminates the negative effects of bubbles; darkroom environment eliminates background light interference;
● Flow equalization and filtration measurement chamber ensures a stable flow field, eliminating sudden jumps in measurement data;
● Integrated installation with a stable internal pressure-reducing and flow-stabilizing mechanism, making on-site installation simple;
● The sensing end (sensor) is installed in the central area, preventing reflected light from the front;
● The bottom is not prone to enrichment or sediment accumulation, ensuring representative water samples;
● Pure-surface mounting plate and in-chassis municipal mounting plate provide the optimal on-site solution;
● Pure fluid physics principles and structural layout require no electric drive and are maintenance-free.
➤ Typical Applications
● This product is mainly applied in environmental protection, wastewater treatment, and industrial wastewater sites.
