Meyer filler fill height problems: high fills, low fills and no fill
Fill height problems on a Meyer filler almost always trace back to one of four things: counter-pressure in the bottle, the liquid valve and vent tube, the bowl level, or how the valve is closed. Before moving a fill height sleeve, work through the causes below. Moving the sleeve outside its normal range only hides the real problem.
No fill
Likely cause
What to do
No counter-pressure in the bottle
Fix the counter-pressure problem first (see the counter-pressure guide).
Liquid valve stuck: binding lever fork, bent valve cage or a screen that is not free
Work the valve by pushing up on the vent tube. If it keeps sticking, replace the liquid valve, lever fork or vent tube.
Valve will not open because the stem guide collar has slipped and released spring tension
Reset the guide collar and its set screw or snap ring.
Broken glass in the centering cup
Clear all glass from the centering cup and sealing rubber.
Slow, uneven or restricted flow
Likely cause
What to do
Spreader out of place or damaged
Reposition or replace the spreader.
Debris on the valve screen
Clean the valve thoroughly.
Damaged liquid ferrule
Replace the snift block assembly.
Bent or partly blocked vent tube
Straighten, clean or replace the vent tube.
Neutral position cam set wrong
Reset the neutral cam.
Bowl level above the charging valve
Correct the bowl level (see the level control guide).
Bottle not seated properly by the lift
Check the lift cylinder and stirrup gripper.
High fills
Likely cause
What to do
Loose vent tube or damaged screen
Tighten the vent tube; replace the screen.
Only partial counter-pressure in the bottle
Fix the counter-pressure problem.
Valve not closing completely: closer track too low or weak closer spring
Adjust the closer track and replace weak springs. Check that levers move freely.
Leaking snift valve
Replace the snift seat rubber or broken spring.
Low fills
Likely cause
What to do
Restricted flow into the bottle
Work through the slow-flow causes above.
Bowl level running low
Check the level control, float and blow-off valve.
