SVF128 Vortex flow meter is a smart vortex flow meter utilizing “Kármán vortex” theory to measure the velocity of fluid then calculate the flow rate in volume or mass. VFM128 is to use for various fluids such as gas, steam and liquid. The flow meter come with local or remote display and different type output such as 4-20mA, pulse, RS485 Modbus RTU, Hart for easily integrate into any PLC, SCADA, DCS system. The flow meter can be upgraded with latest wireless connectivity such as Sub-GHz, LoRaWAN, Sigfox, NB-IoT, 3G/4G... allow it to connect to any IoT platform such as Globiots, Azure, AWS...
Typical Applications: Saturated Steam, Super-heated Steam, Compressed Air, Liquid, Industrial Gases: Nitrogen, Oxygen... or Fuel Gas: Natural Gas...
