HydroC™/ MEG MEG Sensor Mono Ethylene Glycol is one of the most important fluids in the modern Oil + Gas industry. Indeed, in many areas of the offshore, the monitoring of MEG has become a necessity. CONTROS’ HydroC™ / MEG is a unique underwater leakage sensor solving the global problems of the in-situ measurements of Mono Ethylene Glycol. Applications include offshore pipeline inspections, leakage detection, water & waste water treatment tasks and risk management solutions. HydroC™ / MEG - Sensor for Mono Ethylene Glycol (Anti-freeze) in water Function principle

MEG diffuses out of the liquid through a special silicone membrane (patented) into the detector chamber. Inside the chamber MEG gas is measured electronically with an adaptive analysing system and converts into the output signals. Patent pending.
