In a perfect scenario, the oil in a refrigeration or air conditioning system would stay inside the compressor’s crankcase to lubricate the compressor’s moving parts. However, because of ever-changing heat loads on the system and varying system conditions there is no such thing as a perfect system in the real world.
Ultrasonic sensor measures and documents refrigerant-to-oil ratio
February 1, 2016
SensoTech’s LiquiSonic® analyzer allows for precision measurement of oil concentration in refrigerant to ensure the optimum ratio of oil and refrigerant. According to SensoTech, the LiquiSonic sensors use ultrasonic technology to continuously and directly measure the oil concentration.
Checking the acidity and/or moisture content of refrigerant oil is one of the methods used to test if a refrigeration system is clean and uncontaminated. But how can you take an oil sample without an oil plug?
