US Patent:

7296482, Nov 20, 2007

Filed:

Jul 8, 2003

Appl. No.:

10/614759

Inventors:

Joseph W. Schaffer - Greenwood IN, US
Dean Sylvia - The Woodlands TX, US

Assignee:

Endress + Hauser Flowtec AG - Reinach

International Classification:

G01F 1/00

US Classification:

73861

Abstract:

A flowmeter suitable for replacement of differential pressure flowmeters comprising: a primary flow sensor, sensor electronics for proving a measurement signal; a signal processing unit for determining the flow, which can be set to produce a signal proportional to the flowrate or the square of the flowrate; and an output signal generator for generating an output signal proportional to the signal of the signal processing unit.

Endress + Hauser GmbH + Co. KG - Maulburg

International Classification:

G01F 23/00

US Classification:

73292

Abstract:

A transmitter for providing inventory or inventory transfer information on industrial sites is described, for measurement of mass (M), weight (W), volume (V), level (L) and/or density (p) of a product () in a vessel () comprising: a level sensor (), comprising: a conductive probe () extending into the vessel (), means () for generating and sending short electromagnetic pulses (S) down the probe, means () for reception of echoes (E) of the pulses (S) reflected at a surface of the product (), means () for determining a time of flight (t) needed for a pulse (S) to travel down the probe () and its echo (E) to return, a pressure sensor (), mounted on the probe (), and a signal processing unit () for determining mass (M), weight (W), volume (V), level (L) and/or density (p) based on measurement signals supplied by the level sensor () and the pressure sensor ().

Assignee:

Endress + Hauser Conducta Gesellschaft für Mess-und Regeltechnik mbH + Co. KG - Gerlingen

International Classification:

G01N 21/00

US Classification:

73 103

Abstract:

A measurement arrangement comprising a flexible disposable container and a disposable measurement probe for measuring an analytical property of a medium. The measurement probe is mounted on an inside wall of the disposable container and comprises a sensing element extending into the container, which is ready to use and which produces reliable measurement results. The disposable measurement arrangement comprises a closed capsule containing a buffer solution and a tether connecting said capsule to said probe. The container, the measurement probe, the capsule and the buffer solution are sterilized. The sensing element is inserted in the buffer solution during storage and the capsule is removed from the sensing element during measurement operation.
