System and method for remote metering station sensor calibration and verification

An application system for applying a material to a substrate, the application system comprising:

• a material supply device comprising a main pump and a main flow sensor for monitoring an output of the main pump;
• a remote metering system for receiving the material flowing from the material supply device and applying the material to substrates, the remote metering system comprising:
• a first applicator assembly including a first applicator and a first flow sensor for monitoring an output of the first applicator;
• a second applicator assembly including a second applicator and a second flow sensor for monitoring an output of the second applicator;
• and
• a controller in signal communication with the remote metering station and the material supply device, wherein the controller is configured to:
• 1) perform a first calibration operation, where the controller is configured to a) direct the main pump to pump the material to the first applicator, b) receive a first feedback signal from the main flow sensor and a second feedback signal from the first flow sensor, c) compare the first and second feedback signals, and d) determine a compensation factor for the first flow sensor;
• 2) stop material flow to the first applicator;
• and
• 3) perform a second calibration operation, where the controller is configured to a) direct the main pump to pump the material to the second applicator, b) receive a third feedback signal from the main flow sensor and a fourth feedback signal from the second flow sensor, c) compare the third and fourth feedback signals, and d) determine a compensation factor for the second flow sensor.
