Abstract

The invention discloses a flow velocity acquisition circuit, which comprises an electric signal acquisition module matched with a turbine and used for generating a disturbance electric signal under the interference of the rotation of the turbine, wherein the output end of the electric signal acquisition module is connected with the input end of an electric signal amplification module, the input end of the electric signal amplification module is connected with the electric signal acquisition module, the output end of the electric signal amplification module is connected with the input end of asquare wave generation module, and the input end of the square wave generation module is connected with the output end of the electric signal amplification module. The technical purpose of obtaining the actual refueling amount of the automobile in an energy-saving mode is achieved.

Description

technical field [0001] The present application relates to the field of communications, and in particular, to a flow rate acquisition circuit, a refueling metering circuit and a refueling meter. Background technique [0002] In recent years, with the continuous development of the economy, the number of cars in various places is also increasing year by year, and cars have become the most popular modern means of transportation. Carrying out refueling operation to automobiles is a common operation related to automobiles, and various refueling devices have also appeared on the market. However, as the price of automobile fuel continues to rise, in order to obtain more profits, unscrupulous operators of some gas stations illegally change the metering device of the fuel dispenser, so that the actual fuel output of the fuel dispenser is far lower than the nominal fuel output of the fuel dispenser. How to obtain the actual refueling capacity of the car has become a problem that many ...
