CH₄ FT - Methane sensor - Accurate long-term

The CONTROS HydroC CH₄ is a unique surface methane partial pressure sensor designed for flow through applications like pumped stationary systems (e.g. monitoring stations) or ship based underway systems (e.g. FerryBox). Fields of application include: Climate studies, methane hydrate studies, limnology, fresh water control, aquaculture / fish farming.

All sensors are individually calibrated using a water tank, which simulates the expected water temperatures and gas partial pressures. A proven reference system is used to verify the CH₄ partial pressures in the calibration tank. This process ensures that the CONTROS HydroC CH₄ sensors achieves excellent short and long term accuracy.

Operating principle

Water is pumped through the flow head of the CONTROS HydroC CH₄ sensor. Dissolved gases diffuse through a custom made thin film composite membrane into the internal gas circuit leading to a detector chamber, where the CH₄ concentration is determined by means of Tunable Diode Laser Absorption Spectroscopy (TDLAS).

Concentration dependent laser light intensities are converted into the output signal taking additional sensors within the gas circuit into account.
