    摘要: A flow rate of a fluid flowing in a tubing is determined using a flow meter. The flow meter measures a value related to the flow rate. The tubing has a valve for controlling the fluid flowing through the flow meter. The method of determination of the flow rate includes closing the valve and measuring a first zero flow rate value at a first time and a second zero flow rate value at a second time, estimating an error of the value measurement based on the first and second zero flow rate values, opening the valve and measuring value of the flowing fluid, applying an error correction to the measured value of the flowing fluid, and calculating a corrected flow rate based on the corrected value of flowing fluid.
