| 6591696 | Integral electric pressure probe for aircraft An electric pressure probe for an aircraft comprises: a pitot tube assembly for collecting pneumatically air pressure in the vicinity of the assembly; a strut including one end mountable to a surface of the aircraft, the pitot tube assembly being coupled ... | 07/15/2003 |
| 6094993 | Method for measuring flow rate of a fluid in a conduit A method of measuring fluid flow through a conduit takes a plurality of pressure readings at a high sampling rate preferably of from 15 to 25 samples per second. The square root of each reading is found. An average of those square roots is multiplied by a... | 08/01/2000 |
| 5544526 | Combined aircraft angle of attack and dynamic/static pressure sensor assembly A rotatable airstream direction probe is additionally provided with a dynamic pressure sensing port positioned substantially midway between a pair of pneumatic sensing ports with respect to the probe's stagnation line. Pneumatic output ports may thus be p... | 08/13/1996 |
| 5509313 | Method for measuring flow rate and direction of a fluid in a conduit A method of measuring fluid flow through a conduit first finds a null position then rotates the probe 90° from the null position to be aligned with the true flow direction of the field. The null position is found by incremental movement of the probe thro... | 04/23/1996 |
| 5394759 | Automated flow measuring device A probe for measuring fluid velocity through a conduit has a pitot tube connected to a multiple channel cylindrical tube which is placed within a tubular housing. Drive motors are provided to permit precise rotation and longitudinal movement of the cylind... | 03/07/1995 |
| 5010771 | Fast response, high sensitivity manometric wind sensor A gas flow alternator cyclically connects a microphone to a dynamic flow ssure and then a reference static flow pressure. The microphone converts the pressures to a resultant alternating differential signal providing a first input to a phase-locked ampli... | 04/30/1991 |
| 4717159 | Method and apparatus for seating and sealing a pitot tube type flow meter in a pipe This invention relates to a method for seating a pitot tube type flow meter against the remote wall of the pipe in which it is being installed and subsequently sealing same within the tubular fitting through which it enters the pipe, such method comprisin... | 01/05/1988 |
| 4645242 | High pressure mounting with positive lock This invention relates to an improved high pressure mounting for removably positioning pitot tube type flow measurement devices in a pipeline where the mounting includes a hollow tubular collar welded to the pipe in alignment with a probe-receiving openin... | 02/24/1987 |
| 4498347 | Fluid flow measuring Means for ensuring the accuracy and reliability of fluid flow measurements when the fluid contains substantial quantities of entrained particulates, the measurements being taken with a pitot tube and a pressure-sensing means wherein the pitot tube is disp... | 02/12/1985 |
| 4395232 | Oven control apparatus Disclosed is an apparatus useful in controlling the operation of ovens of the type typically associated with baking food products. Broadly, the apparatus permits the linear display of heat input to one or more zones of an oven responsive to gas flow. Heat... | 07/26/1983 |
| 4331035 | Geometric balance adjustment of thin film strain gage sensors A thin film strain gage structure (10,110) for measuring the strain of an inflectible element (12,112) wherein the gage is formed on a surface (15,115) of the element and includes a sensing resistance (16,116) and an adjusting resistance portion (21,121).... | 05/25/1982 |
| 3977249 | Probe mechanism for three dimensional investigation of conditions in a fluid flow A probe mechanism for three-dimensional investigation of conditions in a fluid flow such as exists in a turbo-machine. A sensing head having five sensing orifices therein is mounted on a movable probe finger. The probe finger is interchangeable and stream... | 08/31/1976 |
