Troubleshooting Guide 

 

Symptom 

Possible Cause 

Method of Correction 

Unit Leaks 

Fittings not tight enough. 
 

 
Sensor assembly cracked 

Tighten fittings (see 
section B4) 

 
Unit must be returned for 
repair (see Section D3) 

No output signal or flow 
indication 

No power or low power 
 

No flow passing through 
unit 
 
 
 
 
 
 
Output shorted or 

overloaded 
 
 

Improper connection 
 

 
 
 

Moisture on internal 
electronics 
 
Output circuitry damaged 

 
 
Liquid not translucent 
enough. 
 

 
 
Attempting to measure 

flows below the specified 
minimum for the unit 

Apply correct power 
 

Display or output should 
read zero if there is no 
flow. Increase the flow 
rate  until a reading is 
obtained. (Do not exceed 
the specified maximum 
flow!) 
 
Check electrical 

connections (see section 
B5) 
 

Check electrical 
connections (see section 

B5) and ensure connector 
is correctly plugged in. 
 

Allow unit to dry out in a 
dry environment. 
 
Unit must be returned for 

repair (see Section D3) 
 
Contact the Omega 
Engineering Service 
Department for 

assistance. 
 
Use higher flow rates. 

Flow indication “bounces” 
or fluctuates 

Flow is actually fluctuating 
 
 
Not using the fittings 

supplied by the 
manuafacturer 
 
Entrapped air or gas 
 

 
Turbulence in tubing or 
sensor 

 
 
Fluctuating input power 

 
 

 
Mechanical sensor 
assembly damaged 

 

Correct flow source to 
obtain steady flow 
 
Use the supplied fittings 

 
 
 
Remove entrapped air 
(see section C2) 

 
Straighten the inlet tubing 
or lengthen it to at least  

6” (150mm) 
 
Correct the power source 

or change to a regulated 
supply 

 
Unit must be returned for 
repair (see Section D3)
