Vortex Flow Meter

Vortex flow meter is developed according to Karman vortex principle to measure the volume flow rate of gas, steam or liquid. ATO provides applicable pipe size from DN15 to DN300. High accuracy vortex flowmeter has fully isolated design, optional LCD display for direct data reading, selectable various signal output like pulse output, 4-20 mA output and RS485 communication. ATO maker in China will also provide quality customized service.

Vortex flow meter


  1. It is simple to install and easy to maintain. Just like gas mass flow meter.
  2. Output is proportional to the flow of pulse signal, no zero drift, high precision.
  3. Simple and firm structure, no moving parts, high reliability, long-term operation is very reliable.
  4. Detection sensor does not directly contact the measured medium, stable performance, long life. The flow meters provided by ATO can be used for a long time
