Title: Turbidimeters
Inventor: SNOWDON CHARLES
IPC: G01N21/51
Filed: 1965-03-12
Abstract: 1,094,779. Turbidometers. INDUSTRIAL RESEARCH & DEVELOPMENTS Ltd. March 11, 1966 [March 12, 1965], No. 10488/65. Headings G1A and G1X. A turbidometer comprises a lamp 10, lens 12 and monochromatic filter 13 which in use cause a beam of light to pass through a liquid in a container 25 of which the turbidity is to be measured, the intensity of the beam of light passing through the liquid being compared with the intensity of the light scattered at right angles to the beam of light and reflected from a mirror 29 parallel to the original beam of light by use of a rotating half-disc 26, which alternately cuts out the original beam of light and the scattered light as it passes to a photo-cell 28 so that the photo-cell produces an alternating output dependent on the two relative intensities, the intensity of the beam of light which has passed through the liquid then being reduced by rotation of one of a pair of parallel discs 20, 20' of polarizing material until it is the same as that of the scattered light, this reduction being a measure of the turbidity of the liquid. The device is automatic in that the alternating output from the photo-cell controls a motor 32 rotating one of the discs 20, 20' by way of an amplifier 31, so that when the two compared intensities are the same the motor 32 stops. The container 25 may be a pipe along which the liquid flows, and the motor 32 may control a potentiometer 32 whose output is fed to a meter 34 and/or chart recorder 35. In an alternative embodiment the photo-cell 28 is dispensed with and an eyepiece is used, the field of view of which is divided so that the beam of light passing through the liquid and the scattered light may be visually compared, and the discs 20, 20' are relatively rotated manually by a knob calibrated to give a measure of the turbidity of the liquid. Nicol prisms may be employed in place of the discs of polarizing material, if desired.
