OVAL VORTEX FLOWMETER Gas purge type

Liquid

Gas

Steam

A thermistor sensor picks up the occurrence of vortex caused by the flow velocity change in the manner -- changes in thermistor temperature -- changes in resistance value -- a train of pulses proportional to the flow velocity and measures the flowrate.
Gas purge type is configured to be purged with a clean gas (room temperature) from an external source to the thermistor sensor. Therefore, the fluid to be measured does not touch the thermistor sensor, permitting accurate flow measurement of gases containing dust and mist, low-temperature gases, or others previously thought difficult to be measured.
