Gas Data's LMSr environmental monitor allows engineers to view progress of tests without having to collect data from site.

Gas Data's LMSr environmental monitor allows engineers to view progress of tests without having to collect data from site.

Data, such as sequential gas samples taken from up to 16 sample points on pipelines or ground bore holes on a landfill site, are gathered from the instrument remotely using the GSM connection to Gas Data.

Designed for medium term site monitoring, the system is based on an electronic instrument with typically 20 channels of measurement, each configured to suit the range necessary for the particular application.

Typical measurement channels are as follows: infra-red/electrochemical gas analysis (methane, carbon dioxide, oxygen, carbon monoxide, hydrogen sulphide etc); pressure measurement (gauge and/or absolute); temperature -10 to +2000C, depending on probe used; gas velocity/flow using anemometer devices; interface to orifice plates and pitot tubes; 4-20mA signals from existing plant, eg gas flare temperature; data logging; and telemetry using mobile phone (GSM or GPRS) technology.

Suitable for outdoor use with minimal or no weather protection, the instrument measures all channels according to how the user chooses to set the data logging parameters.

Power is provided ether by internal batteries (supported by solar if necessary) or a mains supply.
