초록

A flow metering device includes a flow tube, a motor for positioning the flow tube, an outlet nozzle in fluid communication with the flow tube, and an inlet nozzle in fluid communication with the flow tube. The outlet nozzle has an outlet pressure tap and the inlet nozzle has an inlet pressure tap. The inlet nozzle, the flow tube, and the outlet nozzle define a flow path that has a plurality of recirculation zones. At least one of the inlet pressure tap and the outlet pressure tap opens within one of the recirculation zones.
