1. A system for circulating a material in a flow circuit, and for periodically dispensing at least a portion of the material from the system onto a substrate, the system comprising:
a dispenser configured to apply the material onto a surface of the substrate; and
a control system for adjusting the dispensing of the material onto the substrate, the control system comprising:
a pressure sensor configured to detect a pressure of a flow of the material through the flow circuit;
a flow sensor configured to detect a flow rate of the flow of the material through the flow circuit; and
a control circuit in communication with the pressure sensor and the flow sensor, the control circuit configured to:
determine a viscosity of the material based on the detected pressure and the detected flow rate;
compare the determined viscosity to a reference value; and
generate a signal to modify a dispensing pressure of the material in the dispenser based on the comparison, such that the pressure sensor detects a change of the pressure of the flow of the material through the flow circuit,
wherein the control circuit is configured to increase the dispensing pressure when the determined viscosity is less than the reference value, and is configured to decrease the dispensing pressure when the determined viscosity is greater than the reference value.
