Abstract

The utility model discloses a fluid electronic metering device, which is designed for the purpose that fresh beer can be correctly and conveniently metered in a hotel and a restaurant. The utility model comprises an inlet flow passage, an outlet flow passage, a rotating shaft, an impeller, a circuit component, and a housing, wherein, the end part of the housing is provided with the inlet flow passage and the outlet flow passage, and the rotating shaft is fixed in a hollow cavity in the center of the housing through a bearing; the rotating shaft is provided with the impeller. The utility model is characterized in that the impeller and a photoelectric encoder are arranged on the rotating shaft in a concentric state, and a photodetector is arranged in opposite to a blade of the photoelectric encoder. The utility model has the advantages of reasonable and compact structure, visual display, convenient use, etc.

Description

Fresh-beer metering instrument

The utility model discloses a kind of vane method and photoelectric counting method and combines and be used for measuring the meter that fluid flows through volume.

Because the barreled draft beer has catered to consumers in general's taste, sales volume rose significantly in recent years, became the drinks of each grand hotel, wineshop indispensability in summer.But it is available not have special-purpose measurement instrument on the market, so each restaurant, wineshop adopt means lack of standardization such as spring balance, measuring cup to measure sale, and both inconvenient, accuracy also is difficult to guarantee, to such an extent as to usually cause dispute.As the patent No. is 87203301 Chinese patent " bulk beer vending machine ", and it is simple in structure, cost is low, but uses still inconvenient.As the patent No. is the Chinese patent " the light sensation formula flowmeter of water dispenser " of 95222786.x, and it has accurate measurement, advantage easy to use, but it adopts inductiopn rotor, and structure is complicated, shortcomings such as manufacturing cost height.

Therefore the purpose of this utility model is to provide the Fresh-beer metering instrument that a kind of compact conformation is reasonable, measure correctly, use intuitive and convenient.

The technical solution of the utility model is to realize like this.This fluid meter electronics comprises the influent stream road, goes out runner, rotating shaft, impeller, circuit unit, shell, outer casing end has into and out of runner, and shell middle cavity bearing fixing rotating shaft, impeller is arranged in the rotating shaft, it is characterized in that being equipped with one heart in the rotating shaft impeller and photoelectric encoder, over against the photoelectric encoder blade, photoelectric detector is arranged.

Above-mentioned photoelectric encoder is a disk in the rotating shaft, the disk multi-disc blade that evenly distributes; The impeller outside can be equipped with air deflector, and the air deflector sidewall has rectangular inlet; Inlet direction and inlet and air deflector line of centres angle are 40 °～60 °; Circuit unit can be installed in the shell space.

Advantages such as this Fresh-beer metering instrument is owing to the structural design compact and reasonable, and volume can be made small-sized, adopts photoelectric counting, and liquid crystal display makes metering correctly directly perceived again, and is very convenient to use.
