The EFM-SM series intelligent steam flowmeter is a volumetric flowmeter designed to measure real-time and cumulative steam flow based on the Karman vortex street principle. The flowmeter comes with temperature and pressure compensation and is mainly used for measuring and measuring steam flow in industrial and heating pipelines.
Product Features
²1.Simple structure, no moving wear parts, easy to install and maintain.
2. High measurement accuracy and reliability, no need for on-site debugging.
3.Small pressure loss and wide range of measurement.
4. The piezoelectric stress detector is installed behind the vortex generator, reducing the influence of impurities in the medium.
5.The amplification board adopts a unique design and is compatible with both gas and liquid.
6.The installation method is flexible and can be installed vertically, horizontally, or tilted at different angles.
7. Has good anti vibration performance.
