How an Aaliant Strain Gauge Target Flowmeter Works
- Measures flow in terms of dynamic force acting on a fixed body in flow stream
- Bonded strain gauges in a bridge circuit configuration mounted outside the fluid stream translate force into an electrical output (proportional to flow rate squared)
How a Bridge Circuit Works
- Forces from the fluid flow are transferred from the target to the sensing tube
- Four interconnected strain gauges (attached to the sensing tube two on forward side of flow, two on reverse side of flow) produce a four-active arm, bridge circuit
- At zero flow, the bridge circuit is balanced and produces zero output·
- Flow produces strain on the sensing tube
- The bridge circuit becomes unbalanced, producing an output
