Abstract

The invention discloses an open channel automatic flow measurement method based on a dilution method. Tracers such as salt, fluorescent dye and radioactive isotope are adopted, a section is put at theupstream of the open channel water flow with a certain turbulence degree; an instruction is sent out through an A/D single-chip microcomputer, a tracer agent feeding device automatically feeds traceragents, the tracer agents are fully mixed with water, the concentration of water flow is measured through a detection point concentration meter device concentration meter on the downstream detectionsection and then converted into flow, and the method is high in measurement precision, wide in application range, capable of saving time and labor and wide in application prospect.

Description

technical field [0001] The invention relates to an automatic method for measuring flow in an open channel. Specifically, tracers such as salts, fluorescent dyes and radioisotopes are used to drop in the upstream section of the open channel, and after being fully mixed with water, the downstream section is detected and detected. An open channel automatic flow measurement method based on the dilution method controlled by the control system. Background technique [0002] Existing technology: You Bin. Experimental research on measuring the discharge outlet flow by dilution method [J]. Hydrology, 2002, 22 (06): 82-85. There are many kinds of flow measuring instruments, and the dilution method is one of them to detect flow Important method, immediately after the field work is completed, bring the water sample to the laboratory for Cl - analysis, and it can be concluded that Cl - Concentration and time relationship tables and graphs, the part surrounded by the curve is the flow v...
