摘要： A peristaltic pump controller provides control of a positive displacement pump as either an uncalibrated or calibrated flowmeter, or a calibrated dispenser. A calibration constant is calculated, after the pump is primed, to determine the amount of volume output produced by an increment of angular rotation of the pump. The constant is determined during a calibration operation where an arbitrary calibration volume is metered. The controller has a low flow and high flow mode where the low flow mode provides a higher resolution for dispensing. The flow mode of operation is determined by the value of the calibration constant and is automatically set when the constant is calculated. DUring a dispensing operation, the controller will meter fluid to within a predetermined amount of the final volume dependent upon the speed of the pump motor and then dribble in the remaining amount of a batch for precision.

摘要： A peristaltic pump is disclosed which includes a base plate having a pair of reaction members pivotally mounted thereon for movement between open positions spaced outwardly from a rotor about which a compressible flow tube is disposed and closed positions maintaining the flow tube in predetermined relation to the rotor. Each reaction member has a shield plate thereon adapted for cooperation with the shield plate on the other reaction member so as to substantially cover the rotor area when the reaction members are in their closed positions. A locking nut mounted on the base plate is adapted for camming cooperation with the reaction members to draw them into predetermined closed relation relative to the tube and rotor.
