ABSTRACT:
A method of calibrating a zero point of a flow sensor includes the steps of detecting a transition of output of the flow sensor caused in response to a shut down of a fluid, and adjusting the zero point of a characteristic curve representing the output of the flow sensor and a flow rate, such that the indicated flow rate is zero immediately after the transition of the flow sensor output.
