Abstract
The invention relates to a sensor arrangement for providing a sensor signal S indicative of a vapor quality X of a medium flowing within a conduit 38a. A sensor includes a heating element and a temperature sensing element is arranged in thermal contact with a wall of a horizontally arranged portion 38a of the conduit 34. Processing means are disposed to deliver a sensor signal S based on an output of the temperature sensing element 52. The sensor 40 includes a sensor body 46 made of a metal material. The heating element 48 and the temperature sensing element 52 are arranged in thermal contact with the sensor body 46. The invention further relates to a cooling system 10 including at least one evaporator 32 for evaporating an ammonia refrigerant, at least one compressor 12 arranged to compress the evaporated refrigerant, and at least one condenser 18 for condensing the compressed refrigerant, and at least one evaporator pump 30 for pumping the condensed refrigerant to the evaporator 32. A sensor arrangement 50 is arranged at a conduit 34 conducting the refrigerant from at least a portion of the evaporator 32.
