Measurement Method and Uncertainty Evaluation of Flow Velocity in Constant Temperature and Constant Velocity Water Bath
The constant temperature and speed water tank is a device to realize the dynamic response of temperature sensor calibration environment,in which the flow rate is the key performance parameter.In this paper,two ways of tracing the flow velocity of a constant temperature and constant velocity tank are discussed,and the uncertainty e-valuation is carried out.The results show that the product of rotational speed and radius method is obviously less than the uncertainty of the value measured by the current meter method for the ring cylinder structure.
