2.0 Introduction
This manual explains how to use the BIOGAS 5000 portable gas analyser. The BIOGAS
5000 is easy to use, calibrate and configure and enables consistent collection of data for
improved analysis and accurate reporting, whilst helping to check the digester process is
running efficiently.
The 5000 series of gas analysers complies with Part 15 of the FCC Rules. Operation is
subject to the following two conditions:
1) This device may not cause harmful interference.
2) This device must accept any interference received, including interference that may
cause undesired operation.
2.1 Safety instructions
Warning
The 5000 series of gas analysers can be used for measuring gases
from landfill sites and other sources as described in this manual.
The operator may be exposed to harmful gases during the use of the
instrument. Inhaling these gases may be harmful to health and in
some cases may be fatal.
It is the responsibility of the user to ensure that he/she is adequately
trained in the safety aspects of the gases being used and appropriate
procedures are followed. In particular, where hazardous gases are
being used the gas exhausted from the analyser must be piped to an
area where it is safe to discharge the gas.
Hazardous gas can also be expelled from the instrument when
purging with clean air.
The instrument has been designed to be used in explosive
atmospheres as defined by the classification. The instrument can be
configured to measure low levels of several gases, but may not be
certified for use in potentially explosive atmospheres of these gases.
It is the responsibility of the operator to determine the protection
concept and classification of equipment required for a particular
application and whether these gases create a potentially explosive
atmosphere.
Note:Gas analysers are a sensitive piece of scientific equipment, and should be
treated as such. If the equipment is used in a manner not specified by the
manufacturer, the protection provided by the instrument may be impaired.

2.3 MCERTS
MCERTS is the UK Environment Agency's Monitoring Certification Scheme. The scheme
provides a framework within which environmental measurements can be made in
accordance with the Agency's quality requirements. The scheme covers a range of
monitoring, sampling and inspection activities.
The BIOGAS 5000 instrument is MCERTS certified only if:
The MCERTS logo appears on the screen after initial power on.
Note: MCERTS - Cross sensitivity tests using hydrogen sulphide were not carried
out on this instrument. Therefore, users should be aware if H2S is present
on sites, as there may be an interferential effect.
MCERTS promotes public confidence in monitoring data and provides industry with a
proven framework for choosing monitoring systems and services that meet the
Environment Agency's performance requirements.
The Environment Agency has established its Monitoring Certification Scheme (MCERTS)
to deliver quality environmental measurements. The MCERTS product certification
scheme provides for the certification of products according to Environment Agency
performance standards, based on relevant CEN, ISO and national standards.
MCERTS certified instruments have been tested by an independent body to ensure that
they meet certain performance requirements. In addition the manufacturer of an
MCERTS product is regularly audited to ensure that the performance requirements of the
certification are being continually met.
The 5000 series of gas analysers have been certified to Version 3.1 of the ‘Performance
Standards for Portable Emission Monitoring Systems’.
2.4 CIRIA
The CIRIA guideline ‘Assessing the risks posed by hazardous ground gases to buildings’
proposes that gas concentrations and flow rates should be monitored.
As an example methodology, they suggest using a gas analyser to first measure flow
and pressure and then afterwards to measure gas concentration.
The logging profile option offers frequency of data to be collected within a timed period
which, in return, identifies a gas profile of the sample point being monitored, information
about whether the sample point is performing correctly, when the peaks occur and
whether air is drawn in after a certain period. This logging option is available on
firmware software version 1.6.5
Versions of the GA5000 analyser range with internal flow on firmware version 1.6.5 and
above have the ability to take measurements according to the CIRIA guidelines, while
still allowing other users to take the measurements as before.

4.0 BIOGAS 5000 optional products and accessories
4.1 Optional products
The BIOGAS 5000 gas analyser has a number of optional products for purchase which
enhance the usability and enable further analysis of data and reading information.
Note: For more information on the features listed in this section please contact Sales
at Geotech on [phone] or email [email protected].uk.
4.1.1 Pitot tube (optional)
The BIOGAS 5000 gas analyser enables the use of a pitot tube to aid accurate flow
measurement. The pitot tube is used for gas extraction systems and the pressure
readings are taken in mbar. High gas flow is calculated in the analyser in m3/hr
(metres cubed per hour).
4.1.2 Orifice plate (optional)
Geotech recommends the use of orifice plates as good practice when using the BIOGAS
5000 gas analyser, enabling repeatability in flow measurement via a fixed method.
Orifice plates are a specialised product and configuration and Geotech does not
currently manufacture or sell spare parts for this product. Please refer to a specialist
supplier if the use of Orifice plates is required.
4.1.3 Temperature probe (optional)
The BIOGAS 5000 gas analyser has the facility to automatically display and record the
borehole temperature via an optional temperature probe.
When a temperature probe is fitted the temperature reading will be displayed on the
‘Main Gas Read Screen’ and recorded with all other data.
Note: Temperature probes with an Ex label are part of the BIOGAS 5000 Ex
certification SIRA 11ATEX2197X and IECEx SIR11.0089X, and therefore
certified for use under the same conditions as the analyser.
4.1.4 Anemometer (optional)
The BIOGAS 5000 gas analyser has the facility to automatically display and record high
flow via an optional anemometer probe. It is designed to plug into the instrument and
instantly provide a flow indication. An anemometer probe adds flow measurements to
the professional reporting ability of the BIOGAS 5000 range along with gas
concentrations, pressure and temperature.
The anemometer has a simple connection, a narrow diameter measurement head
(11mm), a wide temperature operating range (up to 80oC) and indicates flows up to 40
m/sec.
When an anemometer probe is fitted to the analyser the flow will be displayed in the
‘Main Gas Read Screen’ and recorded with all other data.
Flow can be measured in either m/s (gas velocity) or m3/hr (volume flow rate). In
order to calculate the volume flow rate the pipe diameter will need to be entered into
the instrument, either manually or via the Gas Analyser Manager software.
Note: The anemometer probe is part of the analyser Ex certification BVS
04ATEXE194 for use with ATEX only and is therefore certified for use in a
potentially explosive atmosphere.

4.1.6 Bluetooth dongle (optional)
An optional Bluetooth feature enables the operator to set and utilise Bluetooth
technology. This may be useful when downloading gas readings from the analyser to
the PC instead of connecting the analyser to a PC via a USB lead. Bluetooth may also
be used to transfer Site IDs to other 5000 series gas analysers if required. Bluetooth is
activated by plugging the dongle into a pc USB port and switching on the Bluetooth
option feature in the settings on the analyser.
