The fluid flow monitoring apparatus generally includes an outer housing defining a cavity. The outer housing includes an inlet for fluid to enter the cavity and an outlet for fluid to exit the cavity. Fluid flows through the cavity from the inlet to the outlet. The flow monitoring apparatus also includes an inner housing defining an interior cavity and positioned within the outer housing cavity such that fluid flows through the interior cavity. The inner housing is removably connected to the outer housing such that the inner housing is interchangeable with another inner housing having a different cross-sectional profile. The flow monitoring apparatus further includes a traveler movably disposed within the interior cavity.

The flowmeter includes an inner conduit providing a flow path for pressurized fluid, a protective shield having a plurality of markers providing a visible indicator of the flow rate of the pressurized fluid according to the position of the float in the flow path, and a housing assembly for receiving the inner conduit and the protective shield. The flowmeter also can include a fitting assembly for securely coupling the inner conduit, the flow label, and the housing assembly in-line within a pipeline path. The flowmeter can be calibrated by adjusting the position of the protective shield while in-line within the pipeline path.

Abstract: A measuring system comprises a measuring transducer which includes: a transducer housing with an inlet-side flow divider having exactly four, mutually spaced flow openings and an outlet-side housing end having exactly four, mutually spaced flow openings; four measuring tubes connected to the flow dividers for guiding flowing medium along flow paths connected in parallel; an electromechanical, exciter mechanism for producing and/or maintaining mechanical oscillations of the four measuring tubes; as well as a vibration sensor arrangement reacting to vibrations of the measuring tubes for producing oscillation measurement signals representing vibrations of the measuring tubes.

Abstract: A respiratory flow sensor, which is suitable for use near a patient, covers a broad gas volume flow measuring range with a low breathing flow resistance and good, reproducible measured signal quality at the same time. The respiratory flow sensor has a first air resistance body (3) with a blunt end and with an opposite pointed end. The air resistance body (3) is arranged between the measuring transducer (5), of which there is at least one, and the patient-side end (P) of the respiratory flow sensor. The pointed end of the first air resistance body (3) points toward the measuring transducer (5). A second air resistance body (4) with a pointed end is arranged between the measuring transducer (5), of which there is at least one, and the end of the respiratory flow sensor that is away from the patient. The pointed end of the second air resistance body (4) also points toward the measuring transducer (5).
