Analyzer Description

12.1.

Intended use

The instrument is intended for analyzing the composition of biogases / biomethane / landfill
gases and determine the concentration of several components like CH4, CO2, O2 and H2S.
The instrument may optionally be equipped to monitor several sites in time sharing technique
(cyclical one by one sampling).
In particular, the instrument is not foreseen to serve as a gas detector or as a safety device.
In case of not intended use the guarantee will void. Regular controls, inspections and the
exchange from polluted and exhausted filters by the operator are also an important part of the
determinations "not determined use"- see chapter 9 regular maintenance work.
The SWG-100BIO Ex. is an extractive measuring system. It has maximal 4 sample gas inlets, to
measure the gas concentration from 4 different sample points, one by one. It has an internal
gas pump to suck the sample gas from the sampling points. After the measurement, the sample
gas is vented through the sample gas outlet (Vent).
All sample points are equipped with a flow restrictor orifice, which allows also sampling the gas
from the higher-pressure gas pipe of the engine, while limiting the maximum amount of gas in
case of internal cabinet piping leakage.
