Rosemount Inc. is a subsidiary of Emerson Electric Company. Its headquarters is located in Shakopee, Minnesota , where they manufacture measurement instrumentation such as pressure, temperature, level, DP flow, and wireless, as well as analytical and detection instrumentation for gas analysis, liquid analysis, combustion measurement and flame ...
A curvilinear array ultrasonic transducer for use in medical ultrasonography Inside construction of a Philips C5-2 128 element curved array ultrasound sensor. Ultrasonic transducers and ultrasonic sensors are devices that generate or sense ultrasound energy. They can be divided into three broad categories: transmitters, receivers and transceivers.
Schematic view of a flow sensor. An ultrasonic flow meter is a type of flow meter that measures the velocity of a fluid with ultrasound to calculate volume flow. Using ultrasonic transducers, the flow meter can measure the average velocity along the path of an emitted beam of ultrasound, by averaging the difference in measured transit time between the pulses of ultrasound propagating into and ...
An ultrasonic thickness gauge is a measuring instrument for the non-destructive investigation of a material's thickness using ultrasonic waves. The usage of an ultrasonic thickness gauge for non-destructive testing to check material properties such as thickness measurement, is regular in all areas of industrial measurements.
[3] [4] Dr. Firestone's ultrasonic pulse echo technique for metal defect testing was also later applied in medical diagnosis, giving birth to the field of Echocardiography and to the field of Medical Ultrasonography, generally. [5] [6] [7] Dr. Firestone was the editor of the Journal of the Acoustical Society of America from 1939 to 1957. [2]
A magnetic level gauge pulled out from inside the valve housing on top of a railway tank car in the United States [1]. A magnetic level gauge is a level gauge based on a float device that can experience floatation in both high and low density fluids.
The frequency used in the inspection depends on the thickness of the structure, but guided wave testing typically uses ultrasonic frequencies in the range of 10 kHz to several MHz. Higher frequencies can be used in some cases, but detection range is significantly reduced.
This stands for Level, as in the sound pressure level measured through a microphone or the electronic signal level measured at the output from an audio component, such as a mixing desk. Measurement results depend on the frequency weighting (how the sound level meter responds to different sound frequencies), and time weighting (how the sound ...
