BI-DIRECTIONAL DIFFERENTIAL PRESSURE FLOW SENSOR |
摘要 |
Disclosed is a bi-directional differential pressure flow sensor (10) that is configured to establish a direction and flow rate of a fluid flow. The flow sensor (10) includes a flow restriction member (20), a differential pressure sensor (22), and processing electronics (50). The flow restriction member (20) is configured to produce a pressure drop when placed inline with the fluid flow. The differential pressure sensor (22) is embedded or integral with the flow restriction member and produces a differential pressure signal that is indicative of the pressure drop. The processing electronics (50) produces a flow rate signal that is indicative of the direction and flow rate of the fluid flow as a function of the differential pressure signal.
