Problem Probable Cause Try...
Blank display
Flow rate steadily reads
zero when there is flow
Display reads [ - ]
Flow rate intermittently
drops when there is flow
Jumpy reading
Replace battery pack
Reading will resume when flow increases
Reposition meter for full pipe
Note flow direction arrow, reverse meter
Reposition meter for full pipe or rotate to avoid
bubbles
Check for proper equalization
Use external power source
(allows more flow averaging)
Install chemigation line downstream of meter
(or enough upstream for thorough mixing of
fluids 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 flow
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 fluctuation.
Optional Input and Outputs . An optional cable, factory-
installed or field-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 field 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.
