Operating instructions for turbine flow meter
G
Proceed as follows (items correspond to spare parts list):
Press RESET in order to update total volume.
■ ■
Unscrew the battery cover (item 8).
■ ■
Remove the old batteries.
■ ■
Insert new batteries. O and - icons on batteries and cap (item 1).
■ ■
Replace battery cap properly and screw down tightly. Make sure the seal (item 7) and spring (item 9)
■ ■
are in their correct positions.
The meter will go on automatically and revert to default standby mode. Routine operation may now be
■ ■
continued.
The values of the resettable and non-resettable totals and partial volume will be the same as before.
Neither will the calibration (K) factor change in the case of power failures and/or exchange of batteries. It is
not necessary to re-calibrate the meter after exchange of batteries.
8.2 Cleaning
The measuring chamber of the turbine flow meter can be cleaned only after disconnecting the meter from
the pipeline or spigot. The inlet and outlet must be fully accessible.
Tip
Always make sure that ALL the liquid has been removed from the device before you start cleaning
it.
The turbine flow meter has no filter that needs to be cleaned. Therefore, it is only possible to determine
at the inlet and outlet whether large particles have gotten caught in the meter. If there are any foreign
objects in the meter, they can be removed with a pointed object, such as a small screwdriver, or needle
nose pliers.
Caution!
Never blow compressed air into the meter, since the resulting high speed of rotation can cause the
magnets to become loose!
After removing larger objects, a suitable liquid can be used to rinse out smaller foreign particles. It is best
to use diesel fuel or heating oil for this.
Be careful not to damage the body of the device and the plastic parts.
9. Troubleshooting
Problem Cause Solution
LCD display: No display Loose battery contact Check batteries for good contact
Accuracy of measurements is
insufficient
K FACTOR wrong
Meter operates below admissible
min. flow rate
Check K FACTOR (section 6.3)
Increase flow rate to acceptable
level
Reduced flow rate, no flow at all Turbine blocked Clean measuring chamber
Display flashing „Err 1“ Data stored in electronic memory
are damaged
Sorry, irreparable
Short display of „Err 2“ Limited error reading data (usu-
ally when exchanging batteries)
Control circuit board automa-
tically switches on and off to
restore proper operation
