Gasboard-7300 series thermal mass flowemeters are of high accuracy and easy to install with no moving parts; they are widely applied in measuring coal bed gas, biogas and natural gas. This series flowmeters employed the proven thermal diffusion principle technology, offering mass flow rate measurement, and much higher performance-price ratio compare to other flowmeters like Orifice, Differential-pressure and Vortex.
