INTRODUCTION
This instructions manual provides information of the Gasmet Continuous Mercury Monitoring System
CMM. Please read this manual carefully prior to using the system. Improper use of the system may
damage the equipment.

1GASMET CMM OVERVIEW
1.1 Basic structure
The Gasmet CMM is designed for continuous total mercury (atomic mercury Hg0and oxidized Hg2+,
HgCl2) monitoring and the measurement is based on Cold Vapor Atomic Fluorescence (CVAF).
Integrated high temperature dry thermal converter converts all Hg compounds to atomic mercury.
The Gasmet CMM is designed for on-line measurements. It measures hot, wet and corrosive gas
streams. All sample wetted parts of the Gasmet CMM are heated up to 180 °C.
The Gasmet CMM consists of the Gasmet CVAF mercury analyzer, the Gasmet test gas generator for
atomic mercury and mercury chloride, and the Gasmet Hg dilution probe (Error! Reference source n
ot found.). All parts of the system are 19” rack mounted and are installed on pullout shelves. The
Gasmet CMM includes all power connections and temperature controllers for heated line and heated
sample probe. The operation of the system is fully automatic and controlled by the Gasmet MAUI
application software. Additionally, all functions of the Gasmet CMM can also be performed manually.
The built-in control panel PC and the Gasmet MAUI software control the CMM fully automatically. The
measuring data can be transferred from the CMM to control room with analog output 4-20 mA. The
alarms are transferred with relay contacts. The Gasmet CMM provides alarm functions such as System
alarm, Service request, Maintenance, Concentration alarm and Result valid.
The Gasmet CMM is air conditioned by a compressor-cooling unit.

2PREPARATION USE OF THE SYSTEM
2.1 Package
The Gasmet CMM is shipped in several cardboard boxes. To open a box, first open the lid of the box.
Remove any additional smaller items on the top of the contents. Finally lift the contents out of the box.
All gas fittings are closed with caps in order to prevent contamination by dirt and dust. Please do not
remove caps until you connect the sample gas lines.
2.2 Contents of the Gasmet CMM delivery
The Gasmet CMM delivery contains following parts:
1. System cabinet with air conditioning, electrical connector plate, vacuum pump, instrumentation
air processing system and electrical and signal cables inside the cabin
2. The Gasmet CVAF mercury analyzer
3. The Gasmet mercury test gas generator
4. The Gasmet sample probe
5. Heated sample lines (lengths according to the application)
6. Accessories
·The Gasmet USB flash drive
oThe Gasmet CMM manual
oThe Gasmet CMM technical drawings
·Printed manuals
·Filter and O-rings for the sample probe
·The gasket of the probe, bolts and nuts
·Insulation rings 6 pieces
2.3 Transportation and storing
All parts of the Gasmet CMM must be stored, installed, and operated in a dry and frost-free place. It
is essential to avoid condensation within the analyzer and the test gas generator. The environment
should be clean enough so that no dirt will accumulate inside the instrument enclosures. Store the
equipment in following conditions:
·0 - 60 °C storage temperature
·0 - 95 % relative humidity, non-condensing
None of the individual instruments of the Gasmet CMM should be exposed to strong mechanical
vibration or shocks. Shocks during transport, for example, can cause serious damage. When
transporting the instruments, use the original boxes with original shock absorbing materials. Transport
always all parts of the system separately.

CMM USER'S MANUAL (E2.51)

2.4 Installation
Improper handling of any components inside the Gasmet CMM may damage the equipment. Thus,
adjusting any components inside the Gasmet CMM voids warranty. Be always very careful if you move
the instrument.
2.4.1 Explosion protection
For your own safety, the Gasmet CMM must not be used in hazardous areas. The
standard cabinet is not explosion proof.
Gasmet Technologies Oy takes no responsibility if the Gasmet CMM is used in
hazardous areas.
2.4.2 Aggressive condensate and temperature
Aggressive condensate may have formed. Wear protected glasses and proper protective clothing.
Wear protective gloves, because surfaces’ temperatures can be high.
The Gasmet CMM must be mounted vertically. An extreme inclination of the system cabinet may
interfere with the operation of the analyzer. The installation location must preferably be free of strong
vibrations, as well. It is recommended that the instrument is operated in the following environmental
conditions:
·0 - 40 °C, optimum 15 - 25 °C, non-condensing
·< 90 % relative humidity at 20 °C, non-condensing
The ambient temperature of installation location must preferably be stable. The Gasmet CMM cabinet
includes air conditioning unit. Never block the air circulation or use The Gasmet CMM in dusty
environments. Dust can block the air circulation and penetrate into the cabinet damaging analyzer’s
electronics.

2.5.1 Mains
Only professional electrician is allowed to do the connections!
Main supply for the CCM is 230/400 VAC 3*(16-32) A TN-S. The conductor area of an electrical cable
is 2.5-6 mm2and it is depended on the length of the electrical cable and sample line. Electricity and
protective earth are connected to connector bar X2. Do not connect power to the system before all
electrical and gas connections are properly made.

CMM USER'S MANUAL (E2.51)

2.5.2 Signals
Alarm signals, System error, Service request, Maintenance, Concentration and Result Valid are
transferred to the control room from connection bar as free relay contacts. Measuring data 4-20 mA
and remote signals are active and electrically isolated to 500 V. Analog output scales can be set in
the CMM MAUI software.
2.5.3 Gases
The system is connected to instrument air (6-8 bars). The air consumption of the system is
approximately 60 l/min. Instrument air hose 8 mm OD is connected to XN3.
2.5.4 Sample line
When connecting a sample line, it should be remembered that nameplate is on the cabinet side.
Sample line is exported to the cabinet though the inlet which located at the top of the cabinet. Inside
of the cabinet will only be a line branched parts. Attaching the probe should be ensured that probe can
be pulled out of the duct without removing the sample line. Sample line is attached 30 cm intervals by
appropriate cable shelf brackets. The minimum bend radius of the sample line is 30 cm. When the
sample line is installed must be ensured that line does not bend too much.
The sample line’s shorter heated branch is connected to the analyzer and the longer one to the test
gas generator. Connectors must be thermally insulated with insulation rings. Electrical and signal lines
and gas tubes are connected according to Table 1 and Table 2.
2.5.5 Probe
Before the probe installation select the optimum sampling point in accordance with general guidelines
or agree on a sampling point with the responsible authorities. Place the sampling point in such a way
that there is sufficient space for installation and removal of the probe. Easy access to the probe must
be ensured to facilitate later maintenance work. Make sure the installation flange has at least 3
degrees downwards orientation compared to the stack.
Figure 3. The probe installation
Probe power supply, valve controls, alarm cables and gas tubes are placed inside the sample line.
Wires are connected to the terminal box, which is located below the probe. It is beneficial to have
instrument air and air pistol near the probe on maintenance point of view (Figure 3 and Table 2).
