Description

Photo-electric reflection type effusion meter

Technical field

This utility model relates to the effusion meter of a kind of liquid meter, particularly a kind of photo-electric reflection type effusion meter.

Background technology

Currently it is faced with the environmental crises such as more and more prominent air and water pollution; device for purifying potable water is one of important solutions of reply water pollution; through exploitation for many years and accumulation; reverse osmosis water purification machine has had good technological progress; but monitor at filter element life; water leakage alarm and the aspect such as protection, aquifer yield statistical accuracy; remain a need for further raising; such as the probe signals that water electric conductivity is detected; it is being subject to the impact of impact of water; easily wear and tear with the contact position of panel, cause the inaccurate of signal. The reliable liquid meter of grade-safe and analyze compound transducer and assist and realize these functions and just seem more and more important.

Summary of the invention

The purpose of this utility model is to provide the effusion meter of a kind of liquid meter, by installing probe cap on probe, solves the Welding Problems between probe and panel.

Structure of the present utility model includes: include liquid cavity, reflective impeller assembly, panel, data acquisition storehouse and top cover, liquid cavity has water inlet and outlet, bottom center has a projection, it is used for placing reflective impeller assembly, reflective impeller assembly is the rotating mechanism being made up of multiple blades and a rotating shaft, the above of each blade has reflecting plate, it is used for increasing reflected light signal intensity, data acquisition storehouse is placed in the top of liquid cavity, and by O side seal between liquid cavity, there is the top of the corresponding reflective impeller assembly rotating shaft of a groove at center, data acquisition storehouse, the embedded steel ball of groove, panel is placed in data acquisition storehouse, top cover provides longitudinally secured power by screw for data acquisition storehouse and liquid cavity, top cover has dividing plate one piece downward, dividing plate traverse panel, photocell on panel and photovoltaic sensing element are carried out light path isolation, panel has temperature sensor, microprocessor, spring needle, photocell and photovoltaic sensing element, TDS probe and the injection moulding of data acquisition storehouse are fixed together, and probe one directly contacts liquid through data acquisition storehouse, and there is probe cap other end, are combined closely with the spring needle on panel by probe cap, the primary signal of sensor collection is processed and computing by microprocessor, and externally output gathers data.

The blade number of described reflective impeller assembly is 8-16 sheet.

Carry out side seal by O between this utility model data acquisition storehouse and liquid chamber, provide bigger compressive resistance relative to end face seal, data acquisition storehouse adopts transparent food level PC injection mo(u)lding, there is good optically and mechanically performance, optical channel is provided for photoelectric induction type counting assembly, reflective impeller supports optoelectronic induction, the reflecting plate that its data-oriented gathers on the blade profile in storehouse dramatically increases reflected light signal intensity, guarantee is provided for accurate counting, the steel ball that data acquisition storehouse central recess is embedded, the friction of rotating shaft when blade rotates can be reduced, photocell and photovoltaic sensing element are carried out light path isolation by downward dividing plate on the one hand, on the other hand panel is played fixation, the introducing of probe cap, solve the contact problems of TDS probe and panel, the contact that just can keep good need not be welded. injection moulding is fixed together with data acquisition storehouse, and probe directly contacts liquid through data acquisition storehouse, it is provided that accurate conductivity readings, thus judging water quality, provides a kind of monitoring instrument for filter element life monitoring.
