Scattering Method Online Turbidity Sensor Anti Interference

KTU310 Online Turbidity Sensor 90 ° Angle Scattering Principle Fiber Structure, Strong Anti-Interference Ability

1.Principle

The KTU310 integrated online turbidimeter is designed and made by the principle of scattering light turbidimeter. When a beam of light enters a water sample, the light is scattered by the turbidity material in the water sample. The turbidity in the water sample can be calculated by measuring the intensity of the scattered light in the vertical direction of the incident light and comparing it with the internal calibration value, the final value is output after linearization.

Tips: AMI Turbiwell

The EPA approved alternative method non-contact nephelometer

This method is unique in that it is an EPA-approved turbidity monitoring method for a non-contact turbidimeter ⁴⁹. As a non-contact, or surface scatter, nephelometer, the AMI Turbiwell is intended for continuous monitoring, like other process or online monitoring instruments. Until 2009, no surface-scatter design was approved by the USEPA.

This design requires that the light source be an LED with a spectral response between 400 and 600 nm. The incident light beam should be angled to reach the water’s surface at a 45-degree angle, +/- 5 degrees. A beam splitter should be used to deflect a small portion of this light beam before it hits the water. This deflected beam is used as a reference signal to monitoring light intensity. The primary photodetector is set at a right angle to the light source and should have a peak spectral response between 400-600 nm. An algorithm then determines turbidity levels based on the light intensity of the scattered and reference signals.

Though it is a surface-scatter design, the total distance traveled by the light beam (from the LED source to the photodetector) should not exceed 10 cm. To be approved by the EPA, this method can only be used for the range of 0-40 NTU. However, the nephelometer itself can be used up to 200 NTU, though these readings will not be considered EPA-compliant.
