The Variable Area Flow meter is an instrument for measuring the flow of liquids or gases in pipelines. It includes a vertical tube through which the fluid flows whose diameter increases from the bottom to the top and a float which can move vertically in the tube. As the flow increases this float moves to a higher position until its resistance to the fluid flow is balanced by the float’s buoyed weight in the fluid, a value which is constant and independent of the flow rate. The position of the float is a measure of the flow rate. The flow rate values can be read on a scale.
Features
- Mechanical display or LCD display;
- Robust and universal;
- The short-stroke design allows the measurement of high flowrate using a relative short metering tube;
- Special application is for hazardous, dangerous or aggressive fluid, for high temperature and high pressure rates;
- All stainless steel design provides a safe measurement of a variety of liquids, gases and steam- The measuring section can be equipped with a heating jacket ;
- Standard rotameter is mounted in a vertical pipeline with flow direction upwards.
