| What statement is true concerning the arrangement and operation of the viscosity sensor as used for sensing the viscosity of heavy fuel oil? |
| A) 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 inversely proportional to the oil viscosity. |
| B) 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. |
| C) 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. |
| D) 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. |
