A protective shield and bracket assembly adapted to cooperate with a flowmeter in which a variable-area flow tube subject to breakage in the course of operation is supported in an upright position within a meter body having a rear wall in a manner exposing all but the rear portion of the tube, whereby the vertical position assumed by a float within the tube may be observed to provide a reading of flow rate. The bracket is formed by a strip which lies against the rear wall of the meter body and is secured thereto, the strip being provided with resilient arms which project forwardly from opposite sides thereof and terminate in fingers to which opposing margins of a channel-shaped transparent plastic shield are attached, whereby the exposed sides of the meter tube are enveloped by the shield to define a safety chamber which confines explosion products resulting from breakage of the tube. Fluid discharged from the shattered tube is exhausted rearwardly from the chamber to prevent injury to personnel in the vicinity of the flowmeter.

An adapter for a vortex-shedding flowmeter serving to render the meter capable of measuring low flow rates below its normal operating range. The flowmeter includes a flow tube forming a passage for the fluid to be measured and an obstacle assembly mounted therein for generating fluidic oscillations which frequency is proportional to flow rate. The adapter includes means that act to restrict the effective area of the fluid traversing the obstacle assembly, whereby for the same velocity of flow past the assembly a smaller amount of fluid is metered. By providing a set of adapters introducing different areas of restriction, the meter is then able to function as a multi-range instrument.
