<p>PURPOSE:To block radio noise intruding into a control circuit by an easy method. CONSTITUTION:The title air flowmeter 1 used for measuring the quantity of intake air into an automobile engine is provided with sensors 570 and 580 in its central housing section 160 and a control circuit 14 in its resin-made central cylindrical section. A metallic circuit container 110 is formed for housing the circuit 14 and through capacitors 50, 51, 52, and 53 are provided through the container 110. In addition, continuity members 19a, 19c, 19d, and 19b which give electrical continuity between the sensors 570 and 580 and circuit 14 are provided and respectively passed through the capacitors 50, 51, 52, and 53. Therefore, even when radio noise gets into the sensors 570 and 580 and members 19, the intrusion of the noise into the circuit 14 can be blocked.</p> |
