Adjustable Bandwidth Filter For Process Variable Transmitter

View page
US Patent:
6594613, Jul 15, 2003
Filed:
Dec 10, 1998
Appl. No.:
09/209134
Inventors:
Kevin Ley - Coon Rapids MN
David C. Bohn - Eden Prairie MN
David L. Wehrs - Eden Prairie MN
Assignee:
Rosemount Inc. - Eden Prairie MN
International Classification:
H04B 1500
US Classification:
702140, 702190, 702191, 702193, 327553, 327555
Abstract:
A process variable transmitter providing a transmitter output representing a process variable sensed by a sensor. The transmitter has a filter with a bandwidth which is automatically adjusted based on noise detected in a sensor output. When the transmitter senses higher sensor noise levels, it automatically decreases the bandwidth to damp noise in the transmitter output. When the transmitter senses lower sensor noise levels, it automatically increases the bandwidth to provide faster response to changes in the process variable.

Liquid Conduction Indication In A Magnetic Flowmeter

View page
US Patent:
6611770, Aug 26, 2003
Filed:
May 25, 2000
Appl. No.:
09/578279
Inventors:
William E. ODonnell - Minneapolis MN
Thomas P. Coursolle - St. Paul MN
David L. Wehrs - Eden Prairie MN
Assignee:
Rosemount Inc. - Eden Prairie MN
International Classification:
G01F 158
US Classification:
702 49, 702 45, 7386111, 7386108
Abstract:
A magnetic flowmeter with an improved liquid conduction indication has a flowtube assembly with a passage for liquid flow and has an electromagnet mounted outside the passage that provides ramped magnetic excitation. An electrode circuit couples through the passage and generates ramp spikes and a flow signal. A processor receiving the flow signal and generating a flow rate output. The processor also receives the ramp spikes and generates a filtered integral of the ramp spikes as a liquid conduction or empty pipe indication.

Electrode Leakage Diagnostics In A Magnetic Flow Meter

View page
US Patent:
6611775, Aug 26, 2003
Filed:
May 23, 2000
Appl. No.:
09/576719
Inventors:
Thomas P. Coursolle - St. Paul MN
David L. Wehrs - Eden Prairie MN
Assignee:
Rosemount Inc. - Eden Prairie MN
International Classification:
G01F 160
US Classification:
702 65, 702 64
Abstract:
A magnetic flow meter has a diagnostic circuit that indicates leakage from flowtube electrodes. The diagnostic circuit couples to the electrodes and to ground. The diagnostic circuit samples diagnostic potentials between each electrode and ground, and then generates a sum of the diagnostic potentials between a first and a second electrode that indicates the leakage. The flowtube includes an insulated tube and an electromagnet. A transmitter circuit couples to the electromagnet and electrodes, and then generates a transmitter output representing a flow rate, which can be corrected for the leakage.

Spectral Diagnostics In A Magnetic Flow Meter

View page
US Patent:
6615149, Sep 2, 2003
Filed:
May 23, 2000
Appl. No.:
09/576450
Inventors:
David L. Wehrs - Eden Prairie MN
Assignee:
Rosemount Inc. - Eden Prairie MN
International Classification:
G01R 2318
US Classification:
702 76, 7386111
Abstract:
A magnetic flow transmitter provides a coil driver output at a selected fundamental to a coil on a flow tube carrying a flow of a liquid. An amplifier amplifies an electrode signal from the flow tube and an A/D converter converts the amplified electrode signal. A digital signal processor (DSP) uses a spectral transform such as a Fourier type transform to generate a flow output based on spectral components at or near the fundamental and a noise diagnosing output based on components at or near a noise frequency.

Magnetic Flow Meter With Unibody Construction And Conductive Polymer Electrodes

View page
US Patent:
7155983, Jan 2, 2007
Filed:
Feb 4, 2005
Appl. No.:
11/052005
Inventors:
David L. Wehrs - Eden Prairie MN, US
Robert T. Chinnock - Victoria MN, US
Assignee:
Entegris, Inc. - Chaska MN
International Classification:
G01F 1/58
US Classification:
7386112
Abstract:
A magnetic flow metering device and method is disclosed for the measurement of corrosive flow streams. The device utilizes a unibody construction wherein the flow conduit is constructed entirely from an insulative, non-conducting material without resorting to a metallic outer housing. The portions of the electrodes in contact with the flow stream are made of a suitable conductive polymer material, resistant to the corrosive media. The electrodes also feature shields that are molded into the electrode assembly to reduce background electrical noise. The invention also utilizes an electrical configuration that actively drives the electrode shield circuit (electrodes as well as cabling) to provide a more accurate measurement of the electromotive force.

System And Method For Detecting Fluid In Terminal Block Area Of Field Device

View page
US Patent:
7521944, Apr 21, 2009
Filed:
Dec 28, 2006
Appl. No.:
11/648198
Inventors:
David L. Wehrs - Eden Prairie MN, US
Assignee:
Rosemount Inc. - Eden Prairie MN
International Classification:
G01R 27/08
G01F 23/00
US Classification:
324694, 324691, 73290 R
Abstract:
A field device detects the presence of fluid in the terminal block area of the field device by generating an alternating current (AC) test current signal and measuring the amplitude of the resulting AC voltage signal. The field device includes a first terminal and a second terminal adapted for connection to a control room through a twisted-wire pair current loop. Impedance of the current loop is increased by the presence of fluid between the first terminal and the second terminal. By providing an AC test current signal to the control loop and measuring a resulting AC voltage magnitude, the impedance of the control loop can be determined. Increased impedance in the control loop indicates the presence of water in the terminal block.

Industrial Field Device With Automatic Indication Of Solids
