<p>A flow sensor (10) having adjustable sensitivity includes a differential pressure sensing element (48) located in an internal compartment (44) within a rotatable cylinder (40). The compartment is connected between diametrically opposite fluid ports (42, 43) on the surface of the cylinder by fluid channels. The sensor (48) is located on a diaphragm (46) partitioning the compartment (44) into a first and a second chamber with the sensor being responsive to a distortion of the diaphragm induced by a differential pressure.</p> |
