5.0 FLOW SENSOR
The Sensor/Sampler has a flow sensor that will detect a flow failure, turn off the pump and indicate a flow
failure to the controller or analyzer. The flow sensor is ignored after the CPU is reset for the first few minutes
of operation to allow the system to prime with sample fluid. The flow sensor is also ignored after a calibration
for two minutes. The flow sensor should trip after ten seconds of no flow which is indicated by the FLOW LED
illuminated in the CPU Module of the Sensor/Sampler.
