Smart monitoring of oil concentration in the refrigerant circuit

November 15, 2021   Don Horne

Decades of experience show that measurements, especially in the refrigerant circuit, are costly and complicated in research as well as in test centres. Sampling is often difficult or not feasible. Therefore, in practice, the ratio between oil and refrigerant is often estimated by indirect methods.

In order to perform these measurements as precisely as possible, SensoTech has developed the inline solution LiquiSonic OCR, which offers unbeatable advantages.
SensoTech places the highest value on precisely measured values when monitoring oil concentration. 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.

Probably the greatest advantage of online oil condition monitoring in real time is the permanent availability of the measured values. Due to the second-by-second updating of the data, the user has precise knowledge of the ratio of oil and refrigerant at all times. Time-consuming adjustment of the oil concentration and delayed measured values in the circuit are thus a thing of the past.

Monitoring of a wide range of refrigerants with one measuring device

SensoTech convinces with sustainable and comprehensive process solutions. 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. Due to the decades of experience and production of the measuring devices, there is almost no refrigerant left which has not yet been measured by SensoTech.

LiquiSonic OCR also convinces users with maintenance-free operation and comprehensive documentation options. The included process adapter ensures easy installation and immediate readiness for use. SensoTech thus offers a compact measuring system with a wide range of functions and options.
