Abstract

The invention is applicable to the field of liquor measurement, and provides a turbidity measuring method. The method includes measuring a refraction parameter of liquor through lighting emission of a light source, and converting the refraction parameter into an electric signal; measuring a scattering parameter under irradiation, and converting the scattering parameter into an electric signal; computing the electric signals converted from the refraction parameter and the scattering parameter by a PLC (programmable logic controller) to obtain a turbidity value of the liquor; displaying the turbidity value. The turbidity measuring method has the advantages that the strengths of transmitting light and scattering light both emitted to water sample beams are measured at the same time through transmitting light and scattering light comparative measurement, and the turbidity is measured according to the strength ratio of the transmitting light to the scattering light, so that influences of aging of the light source on measurement accuracy are eliminated, the advantages of an individual transmitting method or scattering method are inherited, an ascending turbidity measurement range is provided, and measurement adaptability and accuracy can be improved effectively.

Description

technical field [0001] The invention belongs to the field of solution measurement, in particular to a turbidity measurement method, device and turbidimeter. Background technique [0002] Turbidity is an optical effect that results from the interaction of light with suspended particles in a solution, and it characterizes the degree to which light is hindered from passing through a layer of water. The transmission and scattering of light in aqueous solution is a very simple physical parameter of water quality. Turbidity describes the suspended solids in the liquid, but it is not directly measured. Turbidity measures the amount of transmitted light or The amount of scattered light, the smaller the intensity of transmitted light or the greater the intensity of scattered light, the greater the turbidity of the aqueous solution. The turbidity value is the result of the action of all substances present in the water sample. In a sense, turbidity measurement can become a quantitativ...
