Description
Overview
GAOTek thermal air flowmeter is designed for general purpose precise industrial air and gas measurement, monitor or control. The design opts for applications where the display must be separately placed from the meter body or flow channel. The meters are operated with the Siargo’s proprietary MEMS thermal mass flow sensors together with the smart control electronics. The sensor probe surface is passivated with silicon nitride ceramic materials together with a water/oil proof nano-coating for performance and reliability. The current models are ready to connect to 12 mm or 19 mm lines while other pipe diameters can be offered as customized models. The meter body is made of stainless steel that is available for applications of most of the gases.
