Troubleshooting
WARNING!
When troubleshooting, follow all proper safety precautions. Use proper eye protection and hand protection at all times.
Problem Possible Causes Possible Corrective Actions
Unit is not reaching higher flow setpoint Pressure may be less than pressure specified on
order
Meter may not be the correct size
Meter may not be calibrated for correct gas
Gas piping may be too small for required flow
Adjust regulator using a manometer to set
correct pressure while gas is flowing and meter
is open
Call SSi at (513) 772-0060 to discuss a different
size (model) of flow meter
Verify Calibration Report for gas calibration. If the
gas is different than the gas you are flowing
through the meter, contact SSi at (513) 772-0060
to discuss a recalibration.
Verify that the plumbing is adequate for the
maximum flow required through the meter.
Unit is indicating that there is gas flow when no
flow should be present
Zero value is not set on the meter (if gas supply is
shut off)
The shutoff valve may be located upstream of the
flow meter. This causes a zero drift condition
since there is no pressure on the meter.
Verify that the hand valve for gas supply is closed.
If flow is still showing, perform the zero
calibration procedure as shown in the manual.
•
SSi recommends that the shutoff valve be
moved downstream of the meter so that gas
pressure on the meter is always available.
The error will correct itself when gas
pressure is supplied to the meter.
• Another option is to perform a Zero
Calibration. See the Zero Calibration section
on page 15 for more details.
