ABSTRACT:
A plural component dispensing system includes flow monitoring system to interrupt operation and/or provide an audible and/or visual warning signal to an operator if the flow of one component of a plural component material stops or reaches an unacceptable value. In the flow monitoring system, a pilot valve can be connected with a pressure generated to indicate the flow of the monitored component, and with an adjustable pressure indicative of acceptable/unacceptable flows, and can provide an output to interrupt system operation in the event of an unacceptable flow of the monitored component. In systems of the invention where operation is not interrupted, a warning signal can alert the operator to discontinue dispensing the plural component material until the cause of the unacceptable flow condition has been investigated and corrected.
