IF-VF-A Wafer Vortex Flowmeter
IF-VF-A
Reliable flow measurement for steam, gas and liquids — one instrument, three media.
- Accuracy ±1.0% (liquid) / ±1.5% (steam, gas)
- DN15 – DN300
- 4–20mA / RS485
Overview
Product Introduction
The vortex flowmeter measures flow by detecting the frequency of vortices shed from a bluff body. It is the preferred choice for saturated and superheated steam, compressed air and gases, as well as low-viscosity liquids, with integrated temperature and pressure compensation options. Example model — please replace with your actual model details in the admin panel.
