Industrial & Utilities Stack Monitoring Systems
Envirodyne Group (EDG) offers StakSentinelTM a proprietary range of flexible 'Gas Monitoring Systems' which can be configured to satisfy most applications. Both 'Fixed' and 'Portable' units are available, depending on your requirements.
EDG’s 'Gas Monitoring Systems' are ideal for when flame proofing of equipment is not economically feasible or where moisture ingress with the gas can cause problems. StakSentinelTM can be solar powered for mqany remote applications where power is unavailable.
StakSentinelTM is suitable for the sampling and analysis of air borne pollutants such as 'Gas', 'Vapours' and 'Dust'.
StakSentinelTM is suitable for:-

Vapors
Hydrocarbons Water Vapour (Humidity) Fog / Mist |
StakSentinelTM is suitable for all areas where the sample point may/may not be located in close proximity to support services (e.g; electical power), and has been developed for use in audit processes such as required for Greenhouse Gas (GHG) assessments for licence issue and compliance. Installations on the following applications are possible:
Gas Sampling - Brief description
StakSentinelTM has many advantages, including ease of installation and servicing. All working parts are in the one box and unlimited zones may be recorded from one analyser box location.
The sampling process used in StakSentinelTM can be used for multiple monitoring points in a network arrangement that will eliminate the need for 'Discrete Monitoring Systems'. Contact EDG should there be a situation where multiple applications are involved.
Summary of StakSentinelTM advantages are:
Lower capital, operating and calibration costs
Moisture ingress protection
Faster & easier calibration from one point
Multiple sampling points for one analyser unit
Flameproof areas can be monitored easily and economically
Expensive shielded cable not required
System can be configured to avoid RF or EMF effects
Corrosion resistant & high mechanical strength - 316S/S housing and fittings
Minimal analyser downtime during service
Suitable for many 'gas', 'dust' and 'vapour' types & concentrations
Data storage and/or GPRS/GSM data transmission options
The merits of StakSentinelTM and HydroSentinelTM in providing the scope for audit work in validating permits in Carbon Emiussion Trading Markets can be found in the paper: "Live Monitoring of Carbon Emissions for Sustainable International Trade & Exchange" attached in Downloads.

Gas Sampling - Brief description
- For area sources,sampling cones and stainless steel piping are placed in the required area of analysis. For vents sources, sample lines using isokinetic principles are used.
- Stainless steel tubing is run back to the analyser, may be up to 500m away.
- Within the analyser is a sample pump which draws the sample from the site being monitored. The analyser box can be mounted in a non hazardous area.
- The sample flows through the analyser head, which gives an output signal of 4-20mA, or 0-12V, which are proportional to the concentration.
- The output signal can be viewed on a digital read-out or chart recorders for visual indication of real time analysis.
- The output signal can also be logged and/or retransmitted via a our GRPS/GSM telemetry system - in real time.
