Fluid e.g. fuel, density measuring device for use in engine test bed, has fluid inlet that is controllable by fluid temperature detected by sensor so that support unit temperature is adaptable to inflowing fluid temperature

摘要

The device has a resonator that is arranged at a support unit (10). A set of fluid pipes is arranged in the unit, where a temperature sensor (7) detects a temperature of a fluid e.g. fuel. The support unit is provided with a fluid inlet (12b), where the fluid inlet is controllable by the fluid temperature detected by the sensor so that the temperature of the support unit is adaptable to the inflowing fluid temperature by the fluid inlet.
