Inline Glycol Concentration Density Meter
The ethylene glycol concentration sensor provides an inline analytical solution to determine the concentration or density of process liquids in industrial process lines. It’s often installed on EO absorber outlet piping, EO stripper feed/outlet piping, hydrolysis reactor outlet piping, evaporator outlets, etc.
Product Features
● Delivers real-time concentration or density measurements for direct product process control;
● Provides accurate and reliable 5-digit (4 decimal places) real-time readings;
● Converts measured physical parameters into standard 4-20mA current signals;
● Displays real-time current and temperature readings;
● Allows direct parameter setting and commissioning on site through simple menu navigation;
● Incorporates pure water calibration, fine-tuning and temperature compensation functions;
● Offers selectable anti-corrosion materials for wetted components;

Working Principle
This instrument leverages an acoustic signal to excite a metal tuning fork, driving it to vibrate at its natural resonant frequency. Notably, the resonant frequency of the tuning fork exhibits a direct correlation with the density of the liquid it comes into contact with—this physical relationship forms the core basis of its measurement capability.
Product Advantages
● Delivers precise measurement results with a minimal error margin of 0.3%;
● Adopts advanced signal processing algorithms to maintain stable real-time data output;
● Supports concentration measurement of multiple substances;
● Allows users to set concentration ranges within the instrument’s operational scope on demand;
● Instant response enables timely adjustments;
● Seamless compatibility with PLC/DCS process control systems;
● Robust waterproof and explosion-proof design;
● Intuitive operation interface and low maintenance demands;
● Automatic data logging and documentation functions.
Applications
Some industrial plants and production facilities could benefit from the inline glycol concentration meter:
● Industrial refrigeration plants for glycol coolant circulation systems to monitor glycol concentration in real time, balance antifreeze performance and heat transfer efficiency, and prevent pipeline freezing or excessive energy consumption;
● Automobile manufacturing factories for antifreeze production lines to track glycol concentration in mixing tanks and filling stations, ensuring product meets antifreeze standards and labeling specifications;
● Chemical and pharmaceutical plants for reactor cooling circuits to maintain stable glycol concentration, guarantee precise temperature control during reactions, and improve product quality consistency;
● Oil and gas fields for wellhead antifreeze injection systems to keep glycol concentration within the optimal range, prevent crude oil pipeline freezing and blockage, and ensure continuous production operations;
● Wind power plants for gearbox cooling systems to monitor glycol concentration in cooling loops, protect gearboxes from low-temperature damage, and extend equipment service life;
● Food and beverage cold storage facilities for secondary refrigerant systems to maintain glycol concentration stability, ensure consistent low-temperature storage conditions, and preserve the quality of refrigerated goods.
