Measurement in exhaust gas, dust, condensation atmosphere, etc., and measurement of the flow rate of corrosive gases.
■Features ●Measurement in dust-laden and high-humidity environments This is a highly durable sensor with a very low possibility of damage due to wear or adhesion from dust, as it does not use moving parts or heaters. It is capable of measuring wind speed in dust-laden environments. Additionally, it can measure flow rates in high humidity, condensation environments, and corrosive gas conditions. In cases of dust adhesion, it can also be cleaned. It is suitable for use in explosion-proof areas (ATEX certified). ●Applications Air, exhaust air, activated sludge air, natural gas, exhaust gas, process gas, biogas, incinerator gas, flare gas, engine exhaust gas for transport machinery, exhaust gas from semiconductor manufacturing equipment, and flow rate/flow measurement of various other gases. ●Measured gases Single or mixed gases such as air, nitrogen, oxygen, steam, carbon monoxide, methane, natural gas, ammonia, argon gas, biogas, exhaust gas, etc. For other gases, please inquire.

basic information
■Measurement Principle It is based on the principle of the Karman vortex. When fluid passes through the sensor, the internal rod acts as an obstruction, generating vortices. The flow velocity is calculated by counting these vortices using an ultrasonic sensor built into the vortex sensor. Additionally, since the vortex sensor does not use any electrical components such as moving parts or heaters in the detection section, it is not subject to sensor damage or degradation over time. ■Sensor Usage Example Measurement of intake and exhaust flow rates in mines; the sensor can measure even when salt deposits are present.
