Slurry Density Gauges - Gamma Type
This measurement is based on the principle of gamma ray absorption.
A gamma emitting source and a gamma detector bolt to opposite sides of the process pipe. The absorption of gammas is proportional to mass. The number of gammas arriving at the detector is therefore inversely proportional to the mass of material between the source of gamma and the detector. Since the volume inside the pipe is fixed, this measurement may be calibrated to yields mass per unit volume or Density. The signal requires linearising and other conditioning which is performed by the UNIPRO® transmitter.
This non-contacting measurement technique makes for an extremely simple installation and requires little maintenance. The measurement is performed in real time allowing for fast and efficient Density Control where required.
Being non-invasive, the measurement is unaffected by Process, Pressure, Temperature, Viscosity, Refractive characteristics etc., and does not suffer the wear and corrosion associated with invasive type measurements. This results in reduced maintenance and improved reliability of the measurement.
When coupled to a volumetric flow rate meter, the density gauge can provides accurate determination of wet and/or dry Mass Flow Rate and totalisation.
