How to determine the filling accuracy of the peristaltic pump

     The transmission process of quantitative fluid in the unit of time is called a peristaltic pump filling, filling accuracy refers to the actual filling quantity and filling amount of each target change, the following formula can be used to understand the concept of peristaltic pump filling accuracy: (maximum actual filling quantity minimum actual filling quantity) / average filling time after filling quantity.

By the above formula, we can easily understand that if we can ensure the accuracy of each filling amount, we can ensure the accuracy of filling.

Stepper motor can easily control the angle, during the operation of the motor speed is not affected by the size of the load, can be made open loop control system is accurate, so the general filling system driven stepper motor.
