Smart monitoring of oil concentration in the refrigerant circuit
By Mary Page Bailey and Gerald Ondrey |
LiquiSonic OCR (photo) provides precise real-time readings — without sampling — of oil concentrations in refrigeration lines. The determination of the oil concentration is based on pressure, temperature and sonic velocity measurements in the liquid refrigerant. This measuring principle enables highly accurate and fast adjustment of the desired oil-refrigerant ratio. Because the system monitors in real time, the user continuously has precise knowledge of the ratio of oil and refrigerant. Numerous product data sets (calculation models) can be stored in the controller of the measuring system. This makes it possible to monitor a wide range of refrigerants. The system provides maintenance-free operation and comprehensive documentation options. — SensoTech GmbH, Magdeburg–Barleben, Germany
