The rotameters ROS are used to measurement of volume fluxes or mass of gases in experimental and laboratorial installations. The rotameters can be produced with scale or with graph of flow for another gases. It is possible to produce this rotameters with control valve.
The standard accuracy class is 2,5 according with PN-85/M-42371. On demand there is possible to execute the rotameter in higher accuracy class with calibration certificate from our laboratory, Weights and Measures Office or from Accredited Laboratory.
Changing the application of rotameters or factor’s parameters require of using the correction coefficient. Correct value of mass or volume flux we are received by multiplying the value from scale (graph) by the correction coefficient. This coefficient depends on kind of measuring factor and units of measurement.
Basic elements of rotameters are glass pipe and float.
Material of pipe: glass (allay of boron and silicon) in sort simax or termisil.
Float’s material: allay of Al, chrominium-nickel steel sort 1H18N9T, tarflen, PCV.
Seal of glass pipe: rings for suitable factor.
Connections, including hose ends, may be manufactured from the same material than floats.
In standard version it is aluminium. Flanges and pipe are made of carbon steel.
The rotameter’s shield is made from plexiglass.
