REPORTED PROBLEM POSSIBLE SOLUTIONS
No Signal
• Verify that meter is inserted correctly into the pipe.
• Verify that the electronics enclosure is parallel with the pipe.
• Verify 24 V supply voltage.
• Verify correct wiring to control system (see wiring diagram).
• Check turbine(s) for debris.
Reading is too high or too low
• Verify pipe size. Contact factory if pipe size is different from calibration tag.
• Verify that meter is inserted correctly into the pipe.
• Verify that the electronics enclosure is parallel with the pipe.
• Verify correct wiring to control system (see wiring diagram).
• Confirm that output signals are consistent (frequency vs. analog, etc.)
• Confirm that control system is programmed for correct flow range
or scale factor.
• Check turbine(s) for debris.
Analog signal seems high or
low and does not correspond
to frequency output
Check for ground loop or offset voltage:
• Disconnect analog signal input to control system and measure
analog outputs directly from the flow meter.
• Re-connect signal input to control system and measure the analog
signals again.
• Any difference between these readings indicates a potential ground loop or
offset voltage.
• Please contact ONICON for further assistance.
Control system displays flow
rate, but no flow rate
indication on local display
module or BTU Meter
• Verify that all wires from flow meter were connected to the display
module or BTU Meter.
• The frequency output wire (green) must be connected for any ONICON
Display or BTU Meter.
