14 EL3000 CONTINUOUS GAS ANALYZERS | CI/EL3000-EN REV. B
Material required for the installation (not supplied)
Gas connections
 For the connection of pipelines: Threaded connections with a ⅛ NPT
thread and PTFE sealing tape
Fidas24: Use only metal threaded connectors!
Fidas24: Gas lines
Process gases, test gases and waste air
 PTFE or stainless steel tubes with 4 mm inside diameter and
PTFE or stainless steel tube with at least 10 mm inside diameter for
waste air
 Tube fittings
 Pressure regulator
 Flow restrictor in the combustion gas supply line (see page 34)
 Shut-off valve in the combustion gas supply line (see page 34)
Sample gas
 Heated sample gas line (recommended: TBL 01) or
unheated sample gas line (PTFE or stainless steel tube with inside/
outside diameter 4/6 mm).
The fittings and O-rings required for the connection are included in the
scope of supply and delivery of the gas analyzer.
Flowmeter/flow monitor
 Flowmeter or flow monitor with a needle valve for adjustment and mon-
itoring of the sample gas flow rate and purge gas flow rate if required
 Notes for the selection and use of flowmeters:
 Measuring range 7 to 70 l/h
 Pressure drop < 4 hPa
 Needle valve open
Recommendation: Flowmeter 7 to 70 l/h, Part Number 23151-5-8018474
Shut-off valve
 Install a shut-off valve in the sample gas line (definitely recommended
with pressurized sample gas).
Purging of the gas line system
 Provide a means for purging the gas line system by feeding in an inert
gas, e.g. nitrogen, from the gas sampling point.
Installation material
19-inch housing (Model EL3020)
 4 oval head screws (Recommendation: M6; this depends on the cabinet/
rack system)
 1 pair of mounting rails (Design depends on the cabinet/rack system),
length approx. 240 mm corresponding to approx. 2/3 of the case depth
Wall-mount housing (Model EL3040)
 4 screws M8 or M10
