Problems solved by technology

The general fuel container provides detection of fuel concentration and fuel inventory through expensive metering sensors, which is quite uneconomical for the current large-scale use in portable electrical products
In addition, because in the electrochemical reaction of the fuel cell, many intermediate products or other products will be produced, and the temperature of the fuel may change with the progress of the electrochemical reaction, which will lead to errors in the measurement results

The fluid container comprises a hollow unit used for storing fluid; the metering unit comprises a electrically metering unit and a data processing unit; the electrically metering unit is used for detecting the physical variation of the fluid in the fluid container and then showing its feature electrically; the data processing unit is used for calculating the electrical information and converting it into the physical character of the fluid. The electrically metering unit comprises a metering assembly comprising fasciole assembly; the information detected by the electrically metering unit comprises capacitance value, inductance value and resistance value.

Description

technical field [0001] The present invention relates to a fluid metering device, in particular to provide a metering device for detecting the physical characteristics of the fluid, especially the liquid capacity. Background technique [0002] The known fluid measuring device is used to measure the physical characteristics of the fluid, such as the concentration, density or fluid volume of the fluid. The general fluid measuring device is usually large in size and complex in components, and at the same time, its cost is relatively high because of this result. high. However, products with small size and low cost are also becoming more and more important under the market demand. Taking the fuel cell system as an example, the fuel cell is a battery core that uses hydrogen-rich fuel (such as methanol) to perform an electrochemical reaction with oxygen fuel to output electricity. In the application field of this type of fuel cell, it is necessary to let the user know when the fue...
