What statement is true concerning the arrangement and operation of the viscosity sensor as used for sensing the viscosity of heavy fuel oil?
The viscosity sensor is fitted with a constant speed fixed capacity pump and a capillary tube which produces a pressure drop at constant flow which is proportional to the oil viscosity.
The viscosity sensor is fitted with a constant speed fixed capacity pump and a capillary tube which produces a pressure drop at constant flow which is inversely proportional to the oil viscosity.
The viscosity sensor is fitted with a constant speed variable capacity pump and a capillary tube which produces a pressure drop at variable flow which is proportional to the oil viscosity.
