YOKOGAWA RAKD Small Metal ROTAMETER RAKD-41T3SS-31-VPE-E80 PTFE Valve seat silver indicator

The short-tube Rotameter is used for measurement of low flow rates of liquids and gases. Its special application is in turbulent, opaque or aggressive mediums and under high pressure.
The instrument is mounted in a vertical pipeline with flow direction upwards.
A float is guided concentrically in a conic metal tube.
The position of this float is magnetically transmitted to the indicator.
When the process conditions change the scale needs to
be replaced by a new one of which the values should be calculated.
