摘要： A hot wire flow apparatus for generating a flow rate signal indicative of the actual flow rate of a pulsating fluid flow. The apparatus utilizes a wire element connected with a temperature compensating circuit to generate a flow rate signal indicative of the pulsating fluid flow, but lower in value than the equivalent steady state flow rate. A correction circuit is provided to receive the flow rate signal and generate a corrected flow rate signal indicative of the actual flow rate of the pulsating fluid.

摘要： An intake vacuum sensor with a correction device for determining intake vacuum in an engine intake manifold can correct the sensor output when intake vacuum temperature introduced into the sensor is relatively high or the engine is driven for a relatively long period. The correction device comprises a memory unit for storing a correction coefficient, a correction circuit for correcting the sensor output based on the correction coefficient and a valve means for selectively introducing the intake vacuum and atomospheric air to the vacuum sensor. The memory unit, correction circuit and valve means are operatively responsive to the correction command from an engine control means.
