Abstract
The utility model adopts a luminaire to shoot towards an optical fence through a collecting mirror and the light coming through the optical fence shoots towards a transparent glass pipe. The measured liquid is arranged in the pipeline and a collecting mirror is arranged at the other side of the glass pipe corresponding to the optical fence. The light ejected from the optical fence transmits through the glass pipe and is accepted by a light collection tube after the light gathering, and then the light becomes a plurality of electric impulses with unequal amplitude after the enlargement of an amplifier. A plurality links of the threshold level circuits are connected in parallel behind the amplifier. A plurality links of counters are correspondingly equipped behind the threshold level circuit, and the counters are used to respectively count the pulse with different sizes outputted by different links of threshold levels. The corpuscle with different sizes calculated by the different links of counters is send into a computer to calculate the corpuscle population in the liquid in unit time. The liquid corpuscular counter of the utility model has the advantages of visual and clear detection result, easy use, and convenient operation; the utility model needs no additional sampling to the measured liquid, which avoids the no representativeness of the sampling.
Description
Technical field
The utility model relates to a kind of size and quantity that liquid contains the fine particle number of calculating, for the usefulness of analyzing relevant liquid quality.
Background technology
Population in the general measure liquid need to be selected special medium number, and the viscosity of fluid to be measured is had very big selectivity, and, need sampling in addition during measurement, thereby cause sampling under-represented easily, and can cause cross pollution.
Summary of the invention
The utility model is to be incident upon Yi Guanglan with a light source through condenser, light through the light hurdle is incident upon a transparent glass pipe, fluid to be measured is arranged in the pipeline, glass pipe opposite side corresponding to the light hurdle, an if condenser, optically focused behind the glass pipe is crossed in the transmittance that the light hurdle is penetrated, receive by a photosensitive receiving tube, after amplifying, amplifier becomes the electric pulse that many amplitudes do not wait, number in parallel road threshold level circuit behind amplifier, in threshold level circuit back, relative set is counted the road counter, calculate the pulse of the different sizes of different threshold level outputs respectively, described smooth hurdle is the light that condenser is penetrated, and the aperture through on the sheet metal becomes pointolite, the different sized particles that number road counter meter goes out are delivered to Computing and are gone out the population in the liquid in the unit interval; The threshold voltage that the threshold level circuit is provided with, the pulse height size of decision output, the urea that amplitude is big dashes, be big particle in the liquid, the urea that amplitude is little dashes, and is little particle in the liquid, the utility model has the advantages that, liquid to measuring need not to select special dielectric fluid, to the viscosity of measured liquid very not big select selectivity, viscosity is lower than 10 centipoises and can measures, and, do not need other sampling during measurement, thereby avoided sampling under-represented, and can not cause cross pollution, the utility model measurement result is simple and clear, and is easy to use, simple to operate.
