Table 8-2 Troubleshooting causes and solutions of flow meter not running
Problem
Description
Possible Causes
Solution
No display
Power supply fault
Transmitter fault
Check transmitter power supply and
wiring.
Please contact Walsn or local
distributor.
Touch keys are
unresponsive.
Touch keys locked.
Defaced glass of transmitter.
Transmitter front cover is loose.
Simultaneously press "up" and
"function" keys for 5s.
Clean transmitter front cover glass
Tighten & reboot flow meter
No tube vibration
Faulty wiring between
transmitter and sensor.
Flow meter fault
Verify the connection between the
sensor and the transmitter.
Please contact Walsn or local
distributor.
7.4.2 Flow measurement problems
The typical causes of, and solutions to, this problem are laid out in table 8-3
Table 8-3, flow measurement problem
Problem description
Possible causes of
Troubleshooting
Solution
Flow meter display a
steady non-zero flow
while no flow
External forces on flow
meter
Valve open or leakage
Sensor zero drift
Transmitter incorrectly
configured for sensor
Check for external forces on
flow meter (e.g. pipe
eccentricity, flow meter
enclosure bearing weight)
Ensure valves are properly
seated
Zero calibration
Check sensor and transmitter
serial numbers and calibration
parameters against records
Flow meter display a
fluctuant flow while no
flow
Wiring problems
Radio frequency
interference
Valve open or leakage
Slug flow
Flow tube blocking or
coating.
Vibration interference or
pipe harmonic resonance
Wrong flow unit or low flow
cutoff value
Mounting forces on flow
meter
Check drive gain and detect
voltage
Verify grounding of the
sensor and transmitter
Check the moisture of
junction box
Investigate possible sources
of radio frequency
interference
Ensure valves are properly
seated
Purge flow tube
Ensure flowmeter is isolated
