AVL 415SE Smoke Meter — Maintenance Guide
Filter Mat
We recommend replacing the filter mat during the annual preventive mainte-
nance:
Filter mat set 4152W25./C00.0
Material number: BO3899SP
2.3.12
Pump
Pump noise
Depending on the application, due to permanent use at automatic tests, pres-
sures at or in the system, pressure pulsations of the exhaust gas, exhaust gas
composition and corrosivity of the exhaust gases etc. the pump performance is
affected, this can influence the service life time.
1. Check whether the noise of the pump is atypically or whether the pump is
very noisy.
2. If yes, exchange the pump or at least check the flow of the pump.
Pump flow
Typically the pump flow shall be in a region between 10 … 13 l/min (if
system is heated: up to 15 % lower values related to ambient temperature
of 20 °C).
Test with probe line mounted – maximum 3 m length, clean filter paper
inserted, inlets and outlets of the flow are at ambient pressure.
Flow measurement at inlet or outlet of the measuring system.
A simplified pump function check (as well as a check of the flow behaviour
in the device) is also possible in the Smoke Meter itself:
Flow control: no sampling hose or exhaust gas disposal hose is connected.
The device is already switched on and warmed up or device is switched on
in Service mode.
Setting: single measurement, sampling time is set to 120 sec (2 min).
1. Activate a measurement in measurement mode and the device will take in
air for 2 min.
2. Switch to the Volume Calibration menu.
