Abstract:
1. A method of measuring a specific heat value and a fluid flow rate of a working fluid flowing along a channel at the fluid flow rate, the method comprising the steps of: providing a probe comprising: measuring the specific heat value by carrying out the sequentially executed substeps of: inserting the probe into the working fluid; waiting for a portion of the working fluid to seep into the stagnation chamber; powering the thermal transfer sensor to change a temperature of a portion thereof by a selected amount so as to exchange heat with the fluid in the stagnation chamber and to provide the signal representative of the amount of heat exchanged; and calculating the value of the specific heat of the working fluid from the signal representative of the amount of heat exchanged; and measuring the fluid flow rate by carrying out the sequentially executed substeps of: removing the enclosure from the probe; and inserting the probe into the working fluid and operating the thermal transfer sensor to measure the fluid flow rate.
