AVL 415SE Smoke Meter — Maintenance Guide
– The sampled volume "Vol 415 at 25 °C/1 bar" should be between
20000 and 26000 ml in unheated operation, which matches a pumping
capacity of 10 … 13 l/min.
– In heated operation, the measured value range is about 15 % smaller
(i.e. approx. 17000 to 23000 ml).
Pump
components
1. After about 1 000 operating hours or after 3 months at permanent system
usage at automatic tests, clean or replace the orifices, membranes, dia-
phragms and pump heads.

If the Special Sampling Option (Sample Out Box) is installed, the flow rate
can also drop by around 10 %.
