FLOWRATE™ TECHNOLOGY – HOW IT WORKS

After the pre-infusion stage has completed, the computer determines the remaining time and volume of the extraction. The FlowRate™ (any number between -1 to 1) determines the flow rate of water during the extraction portion of the shot whereby the remaining volume is dispensed in the remaining time. 

   A FlowRate™ of 1      results in a maximum flow rate acceleration during the extraction with the pump beginning at a flow rate of 0 cc/ sec and having the flow rate acceleration such that the total volume desired is dispensed in the total specified extraction time.  

A FlowRate™ of 1 results in a maximum flow rate acceleration during the extraction with the pump beginning at a flow rate of 0 cc/ sec and having the flow rate acceleration such that the total volume desired is dispensed in the total specified extraction time.  

   A FlowRate™ of -1    has the complete opposite flow change – a maximum decelerating rate with the pump beginning the extraction by dispensing water at the maximum speed and decelerating to a stop wherein the total shot volume is dispensed in the total specified shot time. 

A FlowRate™ of -1 has the complete opposite flow change – a maximum decelerating rate with the pump beginning the extraction by dispensing water at the maximum speed and decelerating to a stop wherein the total shot volume is dispensed in the total specified shot time. 

   A FlowRate™ of 0    produces a constant flow rate during the extraction wherein the pump dispenses water at a constant speed until the total volume desired is dispensed in the specified shot time. 

A FlowRate™ of 0 produces a constant flow rate during the extraction wherein the pump dispenses water at a constant speed until the total volume desired is dispensed in the specified shot time. 

   A FlowRate™ of 0.6  approximates the flow rate of a conventional 9 bar shot of a medium roast coffee ground on an espresso grinder.

NOTE: WATER FLOW RATE IS NOT DEPENDENT ON EXTRACTION PRESSURE, but rather extraction pressure is a function of flow rate and coffee grinds resistance. 0 – 14 BAR, Instantaneous flow rate precision.
