A differential float means and sensor means incorporating same.

摘要: A sensor (10) is disclosed for sensing the entrainment of a fluid low specific gravity in higher gravity, particularly refrigerant gas liquid. The typically installed into pressure liquid supply line (24) refrigeration system (26). has differential float (16) including member (54) pivoted about pivot (56) chamber (14) coupled to (24). greater than both fluids which it operates, however, location intermediate length gives nett less one fluids. Hence, can withstand high operation, say 2MPa, and operate as detecting presence or absence lower gravity. also be used gauge snubber (20) replace capillary control tubes.
