OPEN/SHORT SENSOR ICON
No sensors attached
Short in transducer, or in triax transducer cable. Follow
Sensor Connections steps
Sensor Connections
Check sensor connections at TTFM and at sensor junction
box.
Note: Refer to Sensor Cable Resistance Test to test final
connections.
METER READING HIGHER THAN EXPECTED?
Calibration Error
Review calibration menu. Pipe dimensions and fluid
selection/fluid velocity.
Higher flow rate than expected
Investigate pump/valves. Compare velocity with alternate
instrument.
Erratic measurement (set
damping to 0% to check) due to
electrical noise or poor signal
quality.
Ensure all Flowmeter wiring is in METAL conduit and
sensor shield is properly grounded.
Ensure correct power input Ground connection (<1 ohm
resistance).
Ensure 4-20mA Shield connected to Instrument Ground
stud.

High viscosity fluid
Laminar flow profile due to high viscosity fluid requires
an adjustment to Cal Const.
