A Transient Electromagnetic Flowmeter and Calibration Facility
نویسنده
چکیده
Flowmeter and Calibration Facility P.J. Lefebvre Naval Underwater Systems Center, Newport, R.1. An electromagnetic flowmeter was developed to measure transient flows at a data rate of 60 Hz. The approach taken was to develop suitable electronics to replace the electronics ofa commercially available electromagnetic flowmeter normally used W. W. Durgin for steady-state operation. Use of the commercially availableflowmeter body, which Worcester Polytechnic Institute, includes the magnetic coils, core, and signal electrodes, provided a relatively eco Worcester, Mass. nomical means of fabricating the transient flowmeter. A transient flow calibration facility consisting ofa free-falling water column was also designed and built. Results ofthe calibrations are presented and show that theflowmeter can accurately measure transient flows up to the maximum observed acceleration of approximately 1 g.

Critical measurement performance of fluid flowmeters requires proper and quantified verification data. These data should be generated using calibration and traceability techniques established for these verification purposes. In these calibration techniques, the calibration facility should be well-characterized and its components and performance properly traced to pertinent higher standards. The...

• Indicator dilution technics have been employed by Malooly and co-workers J for the in vivo calibration of electromagnetic flowmeter probes. In attempting to apply this calibration procedure to the measurement of pulmonary arterial flow in anesthetized dogs, we noted that the presence of the flowmeter probe on the pulmonary artery was frequently associated with abnormal indicator dilution curv...

An electromagnetic flowmeter incorporated into a catheter is described. The catheter is introduced into the aorta via the femoral artery. The flow sensor is located some distance below the catheter tip and is sensitive to flow at right angles to the catheter. A crater-like elevation at one end of the transducer lumen permits funnel-like connection of the transducer to the ostium of an aortic br...

متن کاملCalibration and Standards in Flow Measurement
Calibration is defined as follows: ‘The set of operations that establish, under specified conditions, the relationship between values of quantities indicated by a measuring instrument or measuring system and the corresponding values realized by standards.’ It is important to recognize at the outset the definition of a ‘calibration’ and to note that the ‘comparison’ applies only to the condition...
