A float moves in a transparent conical measurement tube, relative to the flow. The position of the float depends on the volume flow (weight force versus resistance to flow), and indicates the flow rate on the scaled measurement tube.
●Frontal scale imprint
●Optionally valve
Ranges
Medium water
The details in the table correspond to a vertical inwards flow from below.
Medium air
The details in the table correspond to a vertical inwards flow from below, with the medium at a temperature of 20 °C and a pre-pressure of 1.013 bar.
Handling and operation
●Include straight calming section of 5 x DN in inlet and outlet
●If the media are dirty, install a filter
Options
●Metering ranges and special scales under defined operating pressures / temperatures
Ordering information
●Specify direction of flow, medium, and display range.
●For gases, state pressure (relative or absolute), temperature and medium (e.g. air) (request display range)
