MDS-USC65 Inline Ultrasonic Solids Content Analyzer
The MDS-USC65 Ultrasonic Solids Content Analyzer is a high-performance industrial instrument engineered for real-time, online monitoring of suspended solids and concentration in liquids. Utilizing advanced ultrasonic sound velocity and sound attenuation principles paired with smart temperature compensation, this heavy-duty analyzer delivers laboratory-grade accuracy directly within continuous industrial process lines.
Unlike traditional optical or microwave meters, the MDS-USC65 excels in detecting the solids content of both delicate liquid phases (such as polymer emulsions, adhesives, and pharmaceuticals) and aggressive, high-density solid-liquid two-phase slurries (including mineral slurries, coal slurries, and mud).
Technical Highlights & Features
● Advanced Dual Ultrasonic Principles:
Relies on both sound velocity and acoustic attenuation technologies, providing accurate, highly sensitive, and stable measurements with a rapid, real-time response.
● Immunity to Optical Interference:
The non-optical measurement process is completely unaffected by the solution's color, turbidity, light absorption, or ambient light, making it highly reliable for dark or opaque industrial fluids.
● Automatic Temperature Compensation (ATC):
Equipped with a built-in high-precision temperature sensor that automatically offsets thermal variations, guaranteeing consistent measurement repeatability under fluctuating field conditions.
● Versatile & Adaptable Installation:
Designed to seamlessly fit existing pipeline or tank infrastructures. Supports multiple mounting configurations, including insertion type (for tanks/pools) and inline pipe type (for process loops).
● Customizable Wetted Materials:
To withstand extreme working conditions—from abrasive mineral slurries to corrosive chemical liquids—various premium wetted materials are available to match the chemical properties of your medium.
Comprehensive Application Areas
The robust design of the MDS-USC65 makes it a universally trusted solution across a diverse matrix of industries:
1. Liquid Phase Solids Content (Homogeneous Solutions)
Perfect for calculating the dry matter or solid residues in sticky, high-purity, or chemical fluids:
● Chemicals & Coatings: Polymer emulsions, industrial coatings, paints, and resins.
● Adhesives & Consumer Goods: Water-based glues, latex, paints, and household chemicals.
● Food & Pharmaceuticals: Milk, dairy processing, liquid nutrients, and biopharmaceutical solution profiling.
2. Solid-Liquid Two-Phase Slurries (Insoluble Particles)
Engineered for heavy-duty, highly abrasive environments with high concentrations of suspended solids:
● Mining & Metallurgical: Mineral slurries, flotation tailings, ore concentrates, and thickener underflows.
● Energy & Utilities: Coal-water slurries, fly ash mixtures, and drilling muds.
● Construction & Environment: Mortars, construction mud, river dredging silt, and industrial wastewater sludge.
