• GREEN L.E.D. will light to indicate FLOW.
4. Turn the Sensitivity adjustment counter clockwise until the
RED LED lights to indicate NO FLOW.
5. Turn the Sensitivity adjustment clockwise very slowly until
GREEN LED lights to indicate FLOW.
6. Calibration is now complete.
FINAL SYSTEM CHECK:
• Stop or reduce flow of material and the GREEN LED (FLOW)
will go out and the RED LED (NO FLOW) will light.
MAINTENANCE
Upon final installation of the Series BFM Bulk Flow Monitor,
no routine maintenance is required. A periodic check of
system calibration is recommended. The Series BFM is not
field serviceable and should be returned if repair is needed
(field repair should not be attempted and may void
warranty). Be sure to include a brief description of the
problem plus any relevant application notes. Contact
customer service to receive a return goods authorization
number before shipping.
