Problem
Probable Cause Try...
Blank display
Flow rate steadily reads
zero when there is ow
Display reads [ - ]
Flow rate intermittently
drops when there is ow
Jumpy reading
Replace battery pack
Reading will resume when ow increases
Reposition meter for full pipe
Note ow direction arrow, reverse meter
Reposition meter for full pipe or rotate to avoid
bubbles
Check for proper equalization
Use external power source
(allows more ow averaging)
Install chemigation line downstream of meter
(or enough upstream for thorough mixing of
uids before meter)
Dead battery
Flow is below cutoff (very low)
There is air in the meter
Meter is installed backward
There is air in the meter
Improperly equalized
Pulsing ow
Rapidly changing conductivity
(chemigation applications)

Orange and Blue: Serial Output (Technician Use Only)
Green (+) and White (-): Pulse Output, 30 Vdc max, 10 mA max
Red (+) and Black (-): External Power, 8-32 Vdc at 30 mA max
Drain: Connect to earth ground (See WARNING)
WARNING: Using an unregulated power
supply >18 Vdc may damage the meter
due to AC line input voltage uctuation.
Optional Input and Outputs. An optional cable, factory-
installed or eld-installed by an authorized individual, provides
power input, pulse output* for remote reading (4-20 mA
conversion, telemetry and data logging functions). See diagram
below. Detailed wiring diagrams provided with cable.
IMPORTANT: When eld installing the input/output cable, be
sure to snugly tighten the cable strain relief to prevent water
ingress.
*See High Frequency Output Technical Bulletin for available
pulse rates.
For data logger setup and operation refer to FlowInspector manual.
