Chapter 4: Troubleshooting & Repair

Troubleshooting the Flow Meter

Begin hardware troubleshooting by verifying the following facilities issues are correct (See below
check list). These areas impact system operation and must be corrected prior to performing any
flow meter inspections.

1.

Verify the incoming power to the flow meter is present and of the correct voltage and
polarity.

2.

Check the flow meter wiring for correct connections as described in Chapter 2.

3.

Verify the flow meter is installed with the correct number of upstream and downstream
pipe diameters as shown on pages 12 to 13.

4.

Verify the flow direction indicator is correctly aligned pointing downstream of flow.

5.

Make sure there are no leaks in the line being measured.

After verifying the factors above, follow the troubleshooting procedures outlined below and on
the next page. If you need to return the flow meter to the factory, see page 56 for return shipping
instructions.

Problem

Possible Cause

Solution

Velocity Measurement is
Erratic or Fluctuating

Very erratic or non-uniform flow

Follow installation requirements
shown in Chapter 2

Flow meter installed with less
than required minimum pipe
diameters upstream and
downstream of the sensor

Follow installation requirements
shown in Chapter 2

Insertion sensor probe not
mounted securely

Sensor probe must be mounted
securely without vibration

Sensor component broken

Return to factory for
replacement

Malfunction in system
electronics

Return to factory for evaluation

Ground loop

Check wiring, see Chapter 2

Moisture present in gas flow

Install a water trap or filter
upstream of the flow sensor

Problem

Possible Cause

Solution

Velocity Measurement Seems
Too High or Low

Sensor assembly not aligned cor-
rectly to flow

Correct alignment with the flow
indicator pointing downstream in
the direction of flow

Sensor probe not inserted to the
proper depth

Verify sensing point is located
on the centerline of the pipe

Problem

Possible Cause

Solution

No Response to Flow From

No power

Turn on power to the flow meter
