ABSTRACT:
The invention relates to measuring apparatus for a refrigeration system for detecting a liquid component in refrigerant leaving the evaporator of the system through a suction conduit associated with a heating element heating the tube wall. The measuring apparatus includes a first temperature measuring sensor in thermal contact with the suction conduit located just sufficiently away from the heating element so as to be substantially unaffected by the heating element. A second temperature measuring reference sensor is in thermal contact with the suction conduit an optimum distance downstream from said heating element to provide a reference temperature indicative of the dry temperature of the refrigerant.
