A thermal probe assembly includes an RTD element having an electrical resistance that varies with temperature. A plurality of leadwires is operably coupled to the RTD element. The RTD element is disposed within a sheath and spaced from a distal end of the sheath by a distance selected to provide vibration resistance to the RTD element.

An averaging pitot tube probe assembly for use in sensing a parameter of a fluid flow in a process vessel includes an averaging pitot tube probe extending through the process vessel. The probe includes a first end extending through a first opening in the process vessel, and a second end extending through a second opening in the process vessel. A fixed mount secures the first end in a fixed position relative to the process vessel. A tensioning mount includes a tensioner that is attached to the second end of the probe and is configured to adjust a tension in the probe, and thereby adjust a resonant frequency of the probe.

A self-draining transmitter mount head includes a head body with a transmitter process coupling port in the head body, an impulse port in the head body, and an impulse passage coupled to the impulse port. An impulse drain passage is coupled between the pressure transmitter port and the impulse passage. The impulse drain passage is positioned at an angle to the impulse passage, and relative to a head installation angle that positions the impulse drain passage to drain away from the transmitter process coupling port through a range of head installation angles.

A pressure transmitter coupling for coupling a pressure transmitter to a process fluid includes a process coupling face having a process coupling port configured to couple to impulse piping. A pressure transmitter coupling face is arranged at an angle to the process coupling face, the pressure transmitter coupling face including a pressure transmitter coupling port configured to fluidically couple to the pressure transmitter. A process fluid passageway extends between the process coupling port and the pressure transmitter coupling port. A rod out port is aligned with the process fluid coupling port and configured to receive a cleaning rod therethrough to clean the process coupling port.

A flow measurement probe includes an elongate probe having an averaging pitot tube with a plurality of upstream and downstream openings arranged along a length of the elongate probe, and a thermal flow measurement sensor coupled to the elongate probe. A method of measuring fluid flow rate in a process includes calculating a flow rate of the fluid using differential pressure in upstream and downstream openings of an averaging pitot tube in an elongate probe when the differential pressure is at least a defined measurement threshold, and calculating the flow rate of the fluid with a thermal mass flow sensor coupled to the flow measurement probe when the differential pressure is less than the defined measurement threshold.

A process variable transmitter is configured as a flowmeter for measuring flow of a process fluid through a conduit. The transmitter includes a pitot tube extending into the conduit which creates a differential pressure in the process fluid due to flow of the process fluid. An upstream process variable sensor is mounted on the pitot tube and coupled to the flow of process fluid to sense an upstream process variable of the process fluid. A downstream process variable sensor is mounted on the pitot tube downstream of the upstream process variable sensor and coupled to the flow of process fluid to sense a downstream process variable of the process fluid. Measurement circuitry determines the flow of the process fluid based upon the upstream process variable and the downstream process variable.

Systems, apparatus and methods are disclosed for coupling an averaging picot tube (APT) primary element to a process pipe. A mounting assembly mounts the APT primary element to the process pipe such that a length of the APT primary element extending into the process pipe is adjustable to accommodate different sized process pipe diameters. The mounting assembly includes a weld coupling coupled to the process pipe over an opening in the process pipe and having the APT primary element extending therethrough into the process pipe. An extension pipe nipple is connected to the weld coupling and has the APT primary element extending therethrough such that a transition between a neck section and a sensor section of the APT primary element is positioned inside the extension pipe nipple. A union component, a ferrule, and a cap keep the APT primary element in the mounted position and form a process seal.

Variable line size averaging pitot tube

A customizable duct mount averaging pitot tube (APT) assembly for use with a duct to measure a flow of fluid in the duct is provided. The APT assembly includes an APT primary element extending longitudinally between a first end and a second end. The APT primary element has first and second internal chambers extending longitudinally between the first and second ends. The APT primary element further includes an upstream face with an upstream opening which opens to the first internal chamber and extends from the first end to the second end, and a downstream face with a downstream opening which opens to the second internal chamber and extends from the first end to the second end. First and second duct mount flanges mount the respective first and second ends of the APT primary element to the duct when the APT primary element is inserted in the duct.

Flowmeter for measuring flow of a process fluid through a conduit including process variable sensors mounted on a pitot tube

An apparatus for measuring a process variable of a process fluid based upon a process variable sensor measurement, includes an elongate spool that provides a spool conduit therethrough adapted to be coupled in line with process piping to receive a flow of process fluid. A meter body is carried in the elongate spool and receives the spool conduit therethrough. The meter body has a primary element opening which extends from the spool conduit to outside of the meter body. A carrier is configured to removably mount to the meter body and includes a primary element in the spool conduit through the primary element opening. A process variable transmitter is coupled to the primary element and is configured to measure the process variable of process fluid. The meter body is preferably configured to receive different types of primary elements carried on the carrier.

An apparatus for measuring flow of a process fluid includes an elongate spool providing a spool conduit therethrough adapted to be coupled in line with process piping to receive the flow of process fluid. A meter body is carried by the elongate spool and receives the spool conduit therethrough.
