9.2.3 GEAR FLOW METER
The gear flow meters (A/B/C/D) are cleaned by flushing.
If individual parts have to be cleaned, the flow meter should be disassembled. Care should
be taken that these parts are installed again in their original positions.
1. Remove the electronic sensor (1) from the flow meter.

− The electric sensor can be removed by
loosening the two screws (10) from the holes
without removing the cover (11).
2. Unscrew the screws (2) - two opposite screws
should be left, temporarily screwed in by two turns.
3. Carefully take the lid (3) off the flow meter parallelly.
− If necessary, softly knock on the lid with a
plastic hammer so that it loosens.
− The lid must be removed parallelly so that
the internal bearings are not stressed and the
shaft (5) does not break.
− For this reason do not use screwdrivers as levers.
4. Remove the screws which had previously been left screwed in.
5. Remove the lid, the gears (7) and the shafts (5).
− In most cases a dirt particle in the flow meter causes the problem.
− If the parts cannot be disassembled easily, put the flow meter into a suitable
solvent and then disassemble the parts.
− Do not disassemble the parts by force!
− It is important that the gears turn on the shaft, if they don't, the flow meter is not
suitable for the lacquer.
Contact WAGNER Service Department for further information.
Assembly
After cleaning the gear flow meter and assembling the shafts and gears into the housing,
check whether they turn easily, without any obstruction. This has to be the case even when
a finger slightly presses against the shafts laterally.
1. Mount the lid again in parallel position and adjust it in the correct position by means
of both dowel pins (12).
These pins must never be removed from the flow meter housing.
2. Tighten the screws with 15 Nm; 11.06 lb/ft.
3. Check if the gears turn by using a short pulse of compressed air, maximum 0.1 MPa;
1 bar; 14.5 psi.
4. Mount the electronic sensor again. Do not interchange A/B/C flow meters.
