Gas flows by a heated sensing element and causes cooling down of the element by the mass flow (molecules)
direct mass flow measurement, unaffected by gas pressure and temperature changes
Measurement is based on a PT 100, an additional non-heated sensor is used as a reference.
The amount is directly related to the mass flow.
2. Dew-Point Method
Based on temperature of the biogas and assuming a relative humidity of 100% the water contents can be calculated by standard method – can be used only directly after the digester. Even if a gas cooler is used to dry the gas, directly after the gas cooler the gas is 100% water damp saturated. But gas temperature mustn't be increased due to blowers, direct sun light etc. In these cases temperature method will calculate a wrong (too high) water damp portion.
2. Dew-Point Method
Using a special probe, the relative humidity and so the water contents can be determined. The probe is sensitive against H2S, therefore it can be used only after the filter at very low H2S-concentrations.
