Embodiment Construction
[0023] The invention is a method for conventional metering pumps to realize small-flow and high-precision metering and filling. When the conventional metering pump is adjusted within the flow range of 10-100%, its metering accuracy can reach ±1%. If the flow rate is below 10%, it will The flow control accuracy is low, the cumulative error is large, and the problem of accurate measurement cannot be achieved. The problem to be solved by the method of the present invention is, which configuration of the conventional metering pump can realize the control accuracy of the flow rate below 10%, reduce the cumulative error and can achieve precise measurement.
[0024] full text combination figure 1 For most industries that need to transport fluid materials, the conventional metering pump (5) is used to measure the flow of fluid materials transported by the dosing tank. One side of the dosing tank (1) is equipped with a liquid level gauge (2). The upper and lower ends are connected to ...
