Open the CIPO recordAbstract From the Canadian patent
The present invention is of such construction that a temperature sensor is attached to a vibration sensor which is used for checking the operation of a valve of a steam trap and others by detecting vibrations occurring with the operation of the valve. The temperature sensed by the temperature sensor is converted into a saturated pressure and a true steam leakage corresponding to the steam system pressure is measured from the relation between the vibration level using the pressure as a parameter and the steam leakage. - 8 -
