Compare three different peristaltic pump filling techniques

Compare three different peristaltic pump filling techniques:

First, the angle control technology, which increases the angle control technology during the stoppage based on the number of pulses to control the filling amount, ensures that the peristaltic pump rollers are in the same position each time the machine is stopped, thus eliminating the peristaltic pump pulsation. The effect of the phenomenon on the filling volume, peristaltic pump manufacturers have always believed that the use of this technology to significantly improve the filling of small flows.
Second, using a time timer to control the amount of filling, this method is the easiest to implement, but the error is also large, it is mainly affected by temperature and program structure. In addition, it is not advisable to use the program to accurately generate the time value. When working, the influence of various interrupt operations will lead to time error, and this error is unmeasurable and cannot be compensated.
Third, the number of pulses is used to control the amount of filling. This method can ensure that the total number of angles that the peristaltic pump operates in each assignment is the same, and the filling accuracy is much higher than the time control method.
