3.1 Volumetric Calibration of the peristaltic pump flow 3.2 Calibration of pump flow rate by weight
A short video of peristaltic pump flow calibration can be found at www.lambda-instruments.com/peristaltic-pumps/#video.
The pump speed is proportional to the flow. By determining the total amount of liquid delivered at a given pumping speed over a measured time interval (duration), you can calibrate the flow rate.
Before calibration the pump flow rate, make sure that the liquid completely fills the pump tubing and reaches its free end. Only then initiate the measuring process, for precise calibration.
The calibration of the pump flow rate with speed can be done to know the amount of the liquid pumped.
In the volumetric calibration, the amount of liquid pumped at a particular speed for a minute is calculated. Program the pump with flow rate say 600 and time of about 1 minute.
In the calibration by weight, the weight of the liquid pump in a minute was calculated. Program the MULTIFLOW, HIFLOW, MAXIFLOW and MEGAFLOW peristaltic pumps for the calibration by weight.
