| METS Methane Sensor |
Methane is one of the most important gases in our environment.
Indeed, in many areas of everyday life, the monitoring
of methane is a necessity. The Franatech`s METS is a unique
underwater methane sensor solving the problems of the
in-situ measurements of CH4. Applications range from the
treatment of sewage waters and landfill leachates to water
quality monitoring, from biogas production to climate
change studies and also includes many aspects of the offshore
oil, gas and hydrate exploration activities (e.g. installation
safety, environmental protection, exploration surveys).

Detector type Semi-conductor
Function Principle
The hydrocarbon molecules diffuse
out of the liquid through a
special silicone membrane into the detector room. The
adsorption
of hydrocarbon on the active layer leads to electron
exchange with
oxygen and thus to modification of the resistance, which
the
electronic transduces into a voltage.
