A flow tube liner for a flow tube assembly of a magnetic flowmeter includes a cylindrical wall. The cylindrical wall includes an electrically insulative interior layer and a metallic exterior layer. The exterior layer is bonded to an exterior surface of the interior layer.

Magnetic flowmeter flow tube assembly liner

A field device includes process communication circuitry configured to communicate in accordance with a process communication protocol. A controller is coupled to the process communication circuitry. The controller includes timing circuitry and is configured to generate periodic time signals during an operational period of the field device and store an indication of operational time based on the periodic time signals in non-volatile memory. The controller is configured to employ the process communication circuitry to provide an indication of operational time to a remote device.

Supervisory monitor for energy measurement

A magnetic flowmeter for measuring flow of a process fluid includes a meter body having an opening formed therein. The meter body is configured to be inserted in-line between process piping which carries the process fluid. A moveable extension is coupled to the meter body and configured to extend into the process piping. A coil of wire is carried by the extension and configured to generate a magnetic field. A pair of electrodes sense an EMF in the process fluid generated as a function of the applied magnetic field and flow of the process fluid.

Wafer style insertable magnetic flowmeter with collapsible petals

A magnetic flowmeter for sensing process fluid flow is provided. The flowmeter includes a tube configured to receive the process fluid flow therethrough. A plurality of electrodes is disposed to contact process fluid. At least one electromagnetic coil is disposed proximate the tube. Flowmeter electronics are configured to drive a current through at least one electromagnetic coil and to sense a signal developed across a plurality of electrodes disposed to contact process fluid. A flexible circuit module is disposed proximate the tube, and has at least one flexible circuit containing a plurality of electrical traces electrically coupled to the flowmeter electronics. The at least one electromagnetic coil includes a first coil in the flexible circuit module that is coupled to the electrical traces.

Magnetic flowmeter

A field instrument includes an input circuit having a transistor bridge rectifier which is couplable to a power supply. The transistor bridge rectifier is configured to provide power from the power supply to a remainder of the field instrument.
