SIEMENS SITRANS Flow Meter - Variable Area

 
SITRANS F VA 250 variable area flowmeters with their completely metal design can be used to measure many different types of liquids and gases passing through closed piping. The robust design of the rotameter means that they can also be used in harsh conditions. Different types of flanges, liners and float materials satisfy the requirements of the pharmaceutical and chemical industries


The flow measurement with the SITRANS FVA250 operates on the float principle. As the flowing medium lifts the conical float in the measuring ring, the ring gap expands until an equilibrium is reached between the buoyant force of the medium and the float's weight. The float's height directly corresponds to the flow rate. The float's movement is then conveyed from one magnet to another in the display unit located outside the measuring tube.
