Propylene Glycol Concentration Meter Online
The propylene glycol concentration meter enables real-time monitoring of propylene glycol concentration across the propylene oxide hydrolysis reaction, distillation purification process, product blending and filling process, and wastewater treatment process. For instance, it is installed in the bottom of the finished product tower, where it functions to monitor the concentration of the outlet material at the tower bottom. The advantage of real-time concentration data lies in maximizing reaction efficiency, minimizing energy consumption, and stabilizing product quality. The propylene glycol concentration meter can enhance the concentration accuracy to ±0.2%, making it a key of equipment for improving quality and reducing costs in the industrial production of propylene glycol.
Product Features
● Multiple installation methods are adapted to various operation environments;
● Real-time precise concentration measurement for direct process control;
● Accurate and reliable 5-digit readings with accuracy of ±0.2%;
● Standard 4-20mA current signals for seamless integration with PLC/DCS system;
● Available direct parameter setting and commissioning via intuitive menu of meter on site;
● Advanced pure water calibration, fine-tuning and automatic temperature compensation;
● Explosion-proof design ensures safe operation;

Benefits to Propylene Glycol Production
Maximize reaction efficiency in propylene oxide (PO) stage to avoid excessive energy consumption;
Eliminate possibilities of mis-adjustments in the distillation purification process;
Ensure consistent finished product quality in blending of filling;
Lower long-term maintenance and operational costs for propylene glycol (PG) plants;
Enhances process safety and environmental compliance by PG concentration monitoring in pre-treatment effluent;
Applications
● Propylene glycol production plants for real-time concentration monitoring in propylene oxide hydrolysis reactors, ensuring optimal reaction efficiency and reducing by-product formation;
● Food & beverage factories for propylene glycol concentration control in bakery raw material mixing tanks, beverage flavor dissolution lines, and dairy product moisture-retention systems—maintaining consistent product texture and taste while complying with food additive safety limits;
● Pharmaceutical manufacturing plants for concentration monitoring of propylene glycol in oral liquid solvent blending tanks, ointment matrix preparation vessels, and injection (non-intravenous) dilution lines—ensuring drug solubility and stability, and meeting pharmacopoeia requirements;
● Cosmetics & personal care product factories for concentration control of propylene glycol in cream emulsification tanks, lotion blending lines, and mouthwash production pipelines—balancing product moisturizing performance and skin safety, avoiding irritation caused by excessive concentration;
● Chemical & coating plants for propylene glycol concentration monitoring in water-based paint solvent tanks and polyurethane resin synthesis reactors—ensuring coating viscosity and film-forming quality, and stabilizing resin molecular weight distribution to improve adhesive strength;
● Wastewater treatment facilities in chemical parks for propylene glycol concentration detection in pre-treatment effluent lines—avoiding microbial activity inhibition in biochemical treatment systems due to high PG concentrations, and ensuring compliant discharge of wastewater.
