One of the main advantages of using peristaltic pumps is that nothing, but the peristaltic tubing is in contact with the fluid; this eliminates the risk of the fluid becoming contaminated.
A peristaltic pump is engineering biomimicry at it is best.
They do however come with a slight drawback.
The exact (highly accurate) flow rate of a peristaltic pump cannot be determined just by the tubing type, size, and rotor speed. It can only be estimated.
Numerous factors including the back pressure, variation of the suction conditions and fluid viscosity have a significant influence on the obtained flow rate.
Most importantly, due to the mechanical action, the tubing wears over time. This leads to a drop-off in the volume dispensed and a recalibration must be implemented to maintain the required accuracy of the dispensed volume.
A combination of an Alicat Coriolis flow meter with a built in PID controller, regulating a Longer peristaltic pump creates an accurate and repeatable dispensing system, with up to 0.5% variation/repeatability and most importantly eliminates the need for recalibration.
We offer such flow control systems which includes a touch screen, data logging, online monitoring and clamp on ultrasonic flow sensors.
