MAINTENANCE
Verify Accuracy
Before use, check the turbine’s accuracy and
verify calibration.
1. Make sure there is no air in the system.
2. Measure an exact known volume into an
accurate container.
3. Verify the volume against the readout or
recording equipment.
For best results, accuracy should be verified
periodically as part of a routine maintenance
schedule.
Remove the Turbine
1. Ensure all liquid is drained from the tur-
bine. Wear protective clothing as necessary.
2. Loosen both ends of the turbine. Use a
wrench only on the turbine’s wrench flats.
3. If the turbine is not immediately installed
again, cap lines as necessary.
Clean the Turbine
During use, the turbine should be kept full
of liquid to ensure that drying does not occur
inside the turbine. If drying or caking should
occur, the rotor will stick or drag, affecting
accuracy. To determine if the rotor is stuck or
dragging, gently blow air through the meter
and listen for the quiet whir of the rotor.
During turbine removal, liquid may spill.
Follow the liquid manufacturer’s safety
precautions for clean up of minor spills.
WARNING
CAUTION
Never blow compressed air through the
meter. It could damage the rotor.
Follow the liquid manufacturer’s in-
structions for the disposal of contami-
nated cleaning solvents.
WARNING
1. Remove the turbine from the system fol-
lowing the directions above.
2. When the rotor turns freely, assemble and
install it again following the instructions
above.
Display Electronics
The display electronics are powered by
lithium batteries which provide at least four
years of actual use. If the meter’s readout
should become dim, blank or the low battery
message appears (see below), the batteries
should be replaced. Replacement batteries
can be ordered from the factory. See details
in the Parts Section.
When batteries are disconnected or fail,
values in Batch and Cumulative Totals will
remain. Factory and Field Calibration Curves
are retained in the meter’s computer when
power is lost.
It is strongly recommended that battery check
and terminal cleaning be a part of a routine
maintenance schedule. Battery terminals
should be cleaned annually. Batteries can be
replaced without removing the meter from the
piping system.
