A manifold () with reduced vortex shedding, a vibrator) meter () including the same, and a method of manufacturing both are described. The manifold () comprises a first conduit section (), a second conduit section (), a splitter section () positioned between the first conduit section () and the second conduit section (), the splitter section () including a first splitter face () facing the first conduit section (), and a first protrusion (), at least a portion of which is positioned on the first splitter face ().

Manifold

A vortex flowmeter for measuring a flow rate of a process fluid, including a vortex generator arranged to generate vortices in a flow of the process fluid, a vortex sensor arranged to sense the vortices in the flow of the process fluid and responsively provide a sensor output related to the flow rate of the process fluid, measurement circuitry configured to receive the sensor output and provide a digital output, a memory configured to store measurements based upon the digital output; and diagnostic circuitry coupled to the memory arranged to detect instability in the flow of the process fluid based upon the measurements stored in the memory.

Vortex flowmeter with flow instability detection

A vortex flowmeter includes a flow tube having a first end and a second end. A shedder bar is disposed within the flow tube between the first end and the second end. The shedder bar is configured to generate vortices in fluid flowing through the flow tube. At least one sensor is operably coupled to an external surface of the flow tube and is configured to detect individual deformations of the flow tube resulting from vortices inside the flow tube.

Vortex flowmeter with reduced intrusion by providing piezoelectric sensors externally of the flow tube

A magnetic flowmeter flowtube assembly includes a conduit having an inside diameter, a fluoropolymer liner disposed within and extending through the conduit, and a pair of electrodes mounted relative to the liner to measure a voltage induced within a process fluid flowing through the liner. A venting assembly provides a process fluid vent path from the inside diameter of the conduit to an exterior of the flowtube assembly.

Magnetic flowmeter flowtube with process fluid venting assembly

A flowmeter includes a process sensor assembly providing a sensor signal and a filter stage comprising a low pass filter and a high pass filter and providing a filtered signal from the sensor signal. A processor determines that a filtered signal is indicative of a low flow condition for a first fluid, alters at least one parameter of the low pass filter and at least one parameter of the high pass filter in response to the low flow condition such that the filter stage provides a new filtered signal, determines that the new filtered signal is not indicative of a low flow condition for a second fluid and generates an alarm in response to the new filtered signal not being indicative of a low flow condition for the second fluid.

Anomaly fluid detection

A process fluid sensor for sensing a characteristic of a process fluid is provided. The process fluid sensor includes a metallic sensor body that defines a chamber therein. A piezoelectric crystal element is disposed proximate the chamber and is configured to generate an electrical signal in response to a mechanical input. The piezoelectric crystal element is mechanically coupleable to the process fluid, but is sealed within the sensor body with the exception of a gaseous pathway. A vortex flowmeter utilizing the process fluid sensor is also provided.

Vented high-temperature piezoelectric-based field device

A vortex flowmeter has a vortex sensor and terminals that receive a thermal junction output from a thermowell assembly that is remote from the vortex flowmeter. The vortex flowmeter has a data input that receives data representing a thermal property of the thermowell assembly. The vortex flowmeter has a circuit that receives the first thermal junction output and the vortex sensor output, and that provides a flowmeter output that is compensated for temperature and for the thermal property.

Vortex flowmeter with temperature compensation

A vortex flowmeter measures process fluid flow. The vortex flowmeter includes a conduit that carries the process fluid. A sensing device is housed in a cavity of a sensor body that is coupled to the conduit. A flexure is disposed in a portion of the conduit. The flexure is configured to isolate the process fluid in the conduit from the sensing device. A pathway extends from the cavity to an outer surface of the sensor body.

Leak check device for vortex sensor replacement

A process fluid measurement system provides a first measurement relative to process fluid flowing in a pipe. An additional measurement of process fluid flow velocity in the pipe is combined with the first measurement to provide a simplified indication of mass fluid flow and/or density or other fluid parameter. In some embodiments, the first measurement is a differential pressure measurement. Additionally, one embodiment provides a vortex flowmeter having configurable terminations for coupling to a variety of pressure or differential pressure sensors or transmitters for advanced process fluid measurements or calculations.

Simplified fluid property measurement

An insertion vortex flow meter for measuring a flow rate of a process fluid in a pipe has a mounting assembly, a shedding bar and a sensor assembly. The mounting assembly is attached to a surface of the pipe adjacent an opening in a side wall of the pipe. The shedding bar is inserted through the opening and extends an entire diameter of the pipe. The shedding bar is held in place by a compression force exerted by the sensor assembly on a proximal end of the shedding bar, such that the shedding bar is held by the compressive force between the sensor assembly and an opposing side wall of the pipe. The sensor assembly is adapted to measure motion of a pivoting element corresponding to vortices in the process fluid caused by the shedding bar. The sensor assembly adapted to produce an output indicative of the volumetric flow rate based on the frequency of the measured motion.

Scalable averaging insertion vortex flow meter

A vortex flow meter for measuring fluid flow has a conduit for carrying a fluid. A region of reduced thickness is formed in a portion of the conduit. A shedding bar disposed in the conduit is coupled to the region of reduced thickness and is configured to apply a rocking motion to the region of reduced thickness about a pivot line in response to flow of the fluid. At least one reinforcing rib on the reduced thickness portion preferably extends parallel to flow of fluid.
