Abstract
A device for measuring the speed or flow of a gas at a temperature different from an ambient temperature is provided, which includes: a first platform suspended by first arms above a support designed to be kept at an ambient temperature, the first arms comprising thermoelectric strips designed to supply a first voltage based on the difference between the temperatures of the first platform and the support; and a processing unit designed to supply the speed or flow measurement on the basis of the first voltage, the gas temperature and the ambient temperature.
Claims16
A device for measuring the velocity or flow of a gas at a temperature (Tg) different from an ambient temperature, comprising:
- a first platform suspended by first arms above a support configured for being maintained at the ambient temperature, the first arms comprising thermoelectric tracks configured for supplying a first voltage based on the difference between the temperatures of the first platform and the support;
- and
- a processing unit configured for supplying the measurement (F) of velocity or flow based on the first voltage, the temperature of the gas and the ambient temperature, said platform being free of any heater.
A device for measuring the velocity or flow of a gas at a temperature (Tg) different from an ambient temperature, comprising:
- a first platform suspended by first arms above a support suitable for being maintained at the ambient temperature, the first arms comprising thermoelectric tracks configured for supplying a first voltage based on the difference between the temperatures of the first platform and the support;
- and
- a processing unit suitable for supplying the measurement (F) of velocity or flow based on the first voltage, the temperature of the gas and the ambient temperature;
- a second platform suspended by second arms above the support;
