Erroneous Readings
12
•
Verify that batteries are installed and
contain a charge.
•
The batteries must be replaced.
•
Poor acoustic coupling to pipe. Apply
silicone grease to transducer.
•
Ensure pipe is full of a flowing liquid.
•
If the pipe has a plastic liner, move the
transducer to another location. The
liner may contain an air void.
•
Non-working transducer. Rub
transducer head with thumb for reading.
•
Liquid contains less than 3% total
suspended solids.
•
Move transducer closer to a source of
flow disturbance. (i.e. an elbow, pump
outlet or control valve.)
•
Liquid velocity is greater than 30 FPS [9
MPS].
•
Signal strength is low. Flow readings
may be erroneous. Move the
transducer closer to a source of
hydraulic disturbance.
•
Transducer mounted incorrectly.
•
Another local ultrasonic instrument is
operating at approximately the same
frequency as the UFX.
•
Excessive pipe vibration.
•
Very viscous (thick) liquids will cause
the unit to read lower than actual flow.
•
The pipe is not completely full of liquid.
