As a positive displacement pump, the peristaltic pump has a metering function. The metering effect of a product depends on the design principle of the pump. The peristaltic pump uses a roller to squeeze the pump tube, so the accuracy depends on the inner diameter of the pump tube and the accuracy of the motor. It has a good metering effect in a small flow range. The pharmaceutical filling machine is the metering function of the peristaltic pump. The metering accuracy of the peristaltic pump can reach 1% or even 0.5% under small flow conditions, which is about three to four liters per minute.

Humans developed a smooth forehead with visible, hairy eyebrows capable of a wide range of movement which are able to express a wide range of subtle emotions – including recognition and sympathy
