Description
The short-tube Rotameter is used for measurement of flow rates of liquids and gases. Its special application is in turbulent, opaque or aggressive fluids. The instrument is mounted in a vertical pipeline with flow direction upwards. Inside the special shaped conical metal tube, a float is guided concentrically. The position of this float is magnetically transmitted to the indicator. The indicators are exchangeable without influencing the accuracy.
Features

All wetted parts in stainless steel or PTFE
Measuring accuracy acc. standard VDI/VDE 3513 sheet 2 (qG = 50 %) at calibration conditions
Float damping to avoid float bouncing with gas applications
Optional heat tracing (with steam or fluid heat carrier)
Indicator in steel or aluminum, protection class IP66/67
Mechanical indicator without additional power supply
Microprocessor controlled transmitter with 24 V, 115 V or 230 V power supply
FMEDA report available for SIL application
Limit switches, also available as “fail-safe” version
