MDS-USCD79 Ultrasonic Dual Liquid Phase Separator
The MDS-USCD79 Ultrasonic (Dual) Liquid Phase Separator is a premium, inline phase separation monitoring instrument engineered specifically for automated process control in fine chemical industries. Operating on advanced ultrasonic velocity measurement technology, this smart industrial detector accurately distinguishes between light, mixed, and heavy phases in real time, delivering a fast response to track interface variations seamlessly.
By deploying an innovative dual-sonic measurement scheme, the MDS-USCD79 effectively overcomes the disruptive influences of bubbles, suspended solids, crystals, and turbulence on the detection signal. It guarantees a highly stable, uninterrupted output in complex liquid-liquid systems where traditional sensors fail.
Key Technical Advantages & Features
Advanced Dual-Sonic Technology: Employs a dual-sonic path measurement design that eliminates signal interference from impurities like bubbles, crystals, and suspended matter, ensuring rock-solid data output.
Immunity to Process Variables:
The non-invasive ultrasonic principle is completely unaffected by the liquid's electrical conductivity, density, color, turbidity, flow rate, or pipeline vibrations.
Seamless Automation & Control Integration: Equipped with standard analog output and digital communication interfaces. It also offers an optional 3-channel relay switch output to trigger automated valves or drainage systems instantly.
Flexible Custom Pipe Sizes:
Standard pipe diameters are available, and custom specifications can be tailored on demand to ensure perfect compatibility with diverse pre-existing piping layouts.
Explosion-Proof & Heavy-Duty Construction: Engineered with explosion-proof safety ratings to withstand standard process pipeline pressures, making it fully certified for installation in hazardous industrial zones.
Rugged Environmental Adaptability:
Built to support long-term, continuous online operation in high-humidity and non-condensing environments across a wide ambient temperature range—requiring no additional protective housings.
Primary Applications & Processes
The MDS-USCD79 is widely utilized in downstream reactor lines and continuous process intensification setups where phase interface transitions are critical:
Liquid-Liquid Extraction:
Real-time interface monitoring during organic-aqueous phase extractions.
Washing & Back-Extraction:
Precise control during chemical washing cycles to prevent product loss or cross-contamination.
Oil-Water Separation:
Reliable monitoring for industrial oil-water separators, wastewater skimming, and hydrocarbon processing.
Post-Reaction Phase Separation:
Automating the drainage of heavy/light layers immediately following synthesis reactions.
