Abstract: A system includes a fixed-displacement fluid pump, a motor operatively connected to the fixed-displacement fluid pump, a sensor configured to sense a parameter related to a drive speed of the motor, and a user interface. The pump controller is configured to receive an input from the user interface of a target flow rate of the pump, determine a duty cycle for the motor based on the target flow rate, and control the motor to operate according to the duty cycle. The pump controller is further configured to receive an indication of the sensed parameter related to the drive speed of the motor, determine a measured drive speed of the motor based on the sensed parameter, and iteratively adjust the duty cycle based on a difference between the measured drive speed of the motor and an expected drive speed of the motor.

Abstract: A system includes a pump controller, a user device, and a server. The pump controller transmits identity information via a first communication connection with the pump controller. The server validates the identity information in response to determining that characteristics of the identity information satisfy one or more predetermined validity criteria that are different than the identity information. The pump controller establishes a second communication connection with the server using authentication credentials generated by the server and transmitted to the pump controller in response to validating the identity information. The server transmits a unique activation code to the pump controller via the second connection. The pump controller displays the activation code. A user device associated with a user account transmits the activation code to the server. The server authorizes remote communications with the pump controller via the user account in response to determining that the activation request includes the activation code.
