Yokogawa RAGL Small Laboratory Rotameters Flow Meter
This type of Rotameter is designed for measurement of liquids and gases.
The conical glass metering tube has a free rotating float. This float is mounted in a vertical pipeline with flow direction upwards. The flow is indicated by the top of the float and can be read from the standard scale on the metering tube or from a connected scale.
When the process conditions are changed the scale needs to be replaced by a new one of which the values should be calculated.
FEATURES
- Large selection of measuring ranges
- Anti-static metering tubes for measurement of small
quantities of gas
- High accuracy of free rotating float even at low flow rates
- Low pressure loss
- Visual check of the medium
- Non-powered local indication
- Large selection of scales
- Optional built-in valve
- Exact scale calculation at changed process conditions
according to VDE/VDI guidelines 3513 with the use of
the flow table (option /PT).
