An insertion-type vortex flowmeter that includes an obstruction element removably and replaceably disposed within a pipe. The obstruction element is configured to only partially span the inner diameter of the pipe, and employs multiple flange sub-assemblies to mount the obstruction element to the pipe. The flowmeter also employs a fluid conditioning element that has a major axis that extends axially within the pipe and transverse to the obstruction element.

An external electrode seal assembly (10) for magnetic flow meter tubes (12) is disclosed. The assembly includes a polymeric gasket (36) compressed between a head portion of an electrode (17) and an external seal area (18) of a ceramic tube (12). A stem portion (30) of the electrode extends from the head portion (28) to the interior wall (26) of the tube and is in contact with process fluid flowing through the tube. A clamp assembly (42) compresses the polymeric gasket (36) between the head portion (28) of the electrode (17) and the ceramic tube (12) to form the seal.

A gas chromatograph having a pneumatic detector adapted to produce a component concentration measurement signal that is relatively unaffected by changes in carrier flow rate. The detector includes an orifice connected in the flow stream at the output end of the chromatographic column to produce a pressure signal responsive to density. This orifice signal also responds to flow rate of the fluid passing through the column. A capillary is connected in series with the orifice to produce a second flow-responsive pressure signal which is subtracted from the orifice signal in a way to effectively eliminate changes in the final measurement output signal due to changes in flow rate while leaving the signal variations due to changes in density, i. e. concentration. The orifice and capillary pressure signals are combined subtractively by means of a balanceable force-bar arrangement to which the pressure signals are applied by bellows of predetermined relative sizes, and which is automatically maintained in balanced condition by a rebalance bellows operated by a pneumatic nozzle-flapper feedback device producing the detector output signal.

A resonant wire instrument for producing a measurement signal, which is derived from the resonant frequency of a vibratable wire tensioned in accordance with the magnitude of a physical variable being measured, wherein a force impulse produced mechanically by an apparatus is applied to displace laterally one end of the vibratable wire so as to excite the wire into resonant motion. In one embodiment, the one end is rigidly attached to a housing and a piston applies a transverse force impulse to that end by momentarily striking the housing. In another embodiment, the one end is connected to a piezoelectric crystal which responds to a short-duration electric field to displace momentarily that end. In one species of this other embodiment, the crystal is made to oscillate at the resonant frequency of the tensioned wire by the application of an alternating-polarity voltage signal that is generated by a voltage source having an output connected to the crystal, and a feedback circuit coupled to receive the measurement signal operates to produce a control signal that is used for controlling the voltage source so that the voltage signal being applied to the crystal has a frequency which varies in accordance with changes in the resonant frequency of the wire.

An all-pneumatic process chromatograph having a pneumatically-actuated sample-injection valve, an orifice connected in the column output line to develop a pressure signal corresponding to fluid density, a pneumatic amplifier for strengthening the pressure signal, and pneumatically-operated control means for developing a periodic sample-valve actuating signal and for selecting a particular peak of interest at a controllable time following injection of the sample. The pneumatic control means includes means automatically operable to adjust the time of peak selection in response to changes in actual peak elution time. The temperature-sensitive elements of the apparatus are contained in a chamber which is heated by a source of steam heat, with the rate of heat transfer being regulated pneumatically to maintain a relatively constant temperature within the chamber.

A sensor for use in a vortex flow meter capable of measuring various physical characteristics of a flow in a single process penetration from a common source. A shedder bar in the vortex meter generates alternating vortices. The sensor, which is fluidly connected to the vortex meter, comprises one or more pressure and temperature sensing diaphragms containing piezoresistor elements arranged in a Wheatstone bridge configuration. The sensor produces electric signals indicative of flow velocity, fluid pressure, and temperature. These signals are transmitted to a processing element which computes additional flow parameters.

An electropneumatic motor includes an electrically energizable magnetic circuit with an armature resiliently suspended in the air gap defined between two opposed pole pieces of differing dimensions. One of pole pieces includes an axially adjustable member of magnetic material. A fluid nozzle is carried by the other pole piece. Axial adjustment of the pole piece member affects the strength of the magnetic field. In one embodiment, the pole piece member includes a permanent magnet, which is axially movable relative to the armature, centered in the face of the pole piece. The combination of the fixed field from the permanent magnet and the electromagnetically induced variable field helps more nearly linearize the current to armature force relationship and increases the force on the armature. To determine the operating point of the motor, the suspension for the armature can be prestressed to force it as close as possible to the nozzle, and the magnet can be advanced until the armature is pulled off of the nozzle.

An ultrasonic flowmeter of the upstream/downstream sonic propagation type includes two transducers mounted externally on the same side of a flow conduit. The transducers are coupled to respective sonic probes which transmit and receive acoustic pulses between the transducers through the fluid by "bouncing" the pulses off the opposite pipe wall. Additionally the meter maintains a smooth bore in the measurement region so that the acoustic pulses are refracted at the probe/fluid interface and hence propagate along a sonic path that varies depending on the sonic velocities within the fluid and the probe. An acoustic path of known length is included within at least one of the probes along which a portion of the generated acoustic pulses propagates, thereby providing for a third sonic measurement which represents the transmit time in the probe. The three sonic propagation time measurements are necessary and sufficient to specify the flow velocity independent of sound velocity changes in the fluid and the probe and hence of changes in the path of propagation.
