  • Greyline DFM 5.0 Doppler Flow Meter for Crude Oil Case Study
    Doppler Flow Meters manufactured by Greyline Instruments. Three meters were originally installed. Petrobakken’s lead operator, Terry Willoughby found that the Greyline DFM 5.0 meters measured flow reliably and were unaffected by wax and sand in the oil. Because they work from the outside of the pipe
  • Single Point Current Measurements: Using the Right Instrument in the Right Place (.pdf)
    "sing around" and acoustic backscatter techniques have been developed. Acoustic Doppler Profilers (ADCP) provides exceptional potential to measure current at several layers. These are however, as opposed to one point current meters, unable to measure covariance of current speed and direction
  • Two Technologies
    weak to traverse the pipe. Doppler flowmeters manufactured by Greyline Instruments use a single-head sensor design allowing fast, simple mounting on the outside of pipes. The single-head transducer includes both transmit and receive piezo-electric crystals in the same housing. The Doppler effect
  • MEMS-Based High Throughput Screening
    The customer needs to do frequency analysis to determine the resonant frequency of an oscillating micro-fabricated device. They will use a Laser Doppler Vibrometer to monitor the physical oscillation. This is an instrument that looks at the light reflected from the surface of a moving part
  • Wind Turbines

Such wind maps are usually. done with Doppler radars. which are equipped with stationary. temperature and humidity. sensors. These sensors. improve the average accuracy
  • Portable Grant Data Logger Used In Demanding Clinical Studies
    CAS DataLoggers has recently provided the Grant Squirrel data logging solution for a promising medical research application. The aim of the study was to investigate the effect of interferential current frequencies upon cutaneous blood flow in humans using Laser Doppler Flowmetry (LDF). Strict
  • Zeta Potential Measurement (Aqueous and Non-Aqueous, Iso-Electric Point Determinations)
    undergoing electrophoresis is measured by the technique of laser Doppler electrophoresis. This measured electrophoretic mobility is then converted to zeta potential using established theories. Typically, the particle size of the sample needs to be less than 10 microns and the sample should be dilute
  • Medical Device Link .
    Laser Doppler technology is used to measure microvascular blood flow in a number of medical diagnostic and clinical research applications. Bringing this advanced technology to the patient, however, requires a decidedly low-tech trolley. When Moor Instruments (Millwey, Axminster, UK) decided
