Abstract
This disclosure relates to an improved fluid flow sensing apparatus and a method of operating the apparatus. In particular, it relates to a fluid flow sensing apparatus having a compact design with a microcalorimetry sensor disposed in a fluid flow channel of the apparatus and a controlling means configured to provide a sensor input to the microcalorimetry sensor to set the sensitivity of the microcalorimetry sensor based on a control input corresponding to a property of the fluid.
Claims15
A fluid flow sensing apparatus comprising:
- a fluid flow channel having an inlet and an outlet;
- a microcalorimetry sensor disposed in the fluid flow channel;
- and
- a controlling means for the microcalorimetry sensor, wherein the controlling means is configured to provide a sensor input to the microcalorimetry sensor to set a sensitivity of the microcalorimetry sensor based on a control input corresponding to a property of fluid.
A fluid flow controlling apparatus comprising:
- a fluid flow sensing apparatus comprising:
- a first fluid flow channel having an inlet and an outlet, a microcalorimetry sensor disposed in the first fluid flow channel, a controlling means for the microcalorimetry sensor, wherein the controlling means is configured to provide a sensor input to the microcalorimetry sensor to set a sensitivity of the microcalorimetry sensor based on a control input corresponding to a property of fluid;
- and
- a second fluid flow channel having a respective inlet and a respective outlet, the fluid flow controlling apparatus being configured to split a fluid flow between the second fluid flow channel and the first fluid flow channel such that the first fluid flow channel is configured to receive a predefined proportion of fluid flowing through the second fluid flow channel.
A method for operating a fluid flow sensing apparatus having a microcalorimetry sensor, the microcalorimetry sensor being disposed in a fluid flow channel of a fluid flow sensing apparatus, the method comprising:
- receiving, by a controlling means, a control input corresponding to a property of fluid flowing through the fluid flow channel;
- processing, by the controlling means, the control input to generate a sensor input for the microcalorimetry sensor;
- and
- providing, by the controlling means, the sensor input to the microcalorimetry sensor to set a sensitivity of the microcalorimetry sensor based on the property of the fluid.
