3.2 Description
The device measures the flow of a liquid or gaseous medium.
The medium flows through the flowmeter vertically from bot-
tom to top. The float is lifted by the flow forces. On the upper
reading edge (largest diameter), the flow quantity (in volume or
mass)canbereadonthemeasuringtubescale.
The displayed value only applies for the medium and medium
temperature for which the device has been calibrated.

Installation and connection
5 Installation and connection
5.1 Check operating conditions
WARNING
Splintering measuring tube!
Do not use measuring tube made of PVC for gaseous
media.
1. Ensure the required operating conditions are met:
– Resistance of body and seal material to the medium
(→resistance lists).
– Media temperature (→Data sheet).
– Operating pressure (→Data sheet).
2. Consult with the manufacturer regarding any other use of
the device.
5.2 Planning pipelines
5.2.1 Specify pipes and fittings
1. Ensure installation position:
–vertical
– Direction of flow from bottom to top
– Device is freely accessible from all sides
2. Ensure pipe connection without tension.
– If necessary, equip with expansion shanks or pipe com-
pensators
3. Straight pipe lengths before and after device (recom-
mended to avoid vibration of the float)
– DN = DN device
– Length > 5–7 x DN device
– Length > 10 x DN device for large differences between
nominal diameters between pipe and device
4. If necessary:
– For gaseous media, equip with vent valve at highest
point of inlet and outlet pipe
– For condensing gaseous, equip with vent valve at low-
est point of inlet and outlet pipe
5. Allocate control valves after device.
6. Allocate throttle valves before or after the device.
– For gasses, only after the device (to prevent vibrations
of the float)
5.2.2 Providing safety and control devices
(recommended)
Avoid contamination

1
2
1. With a pen, mark the lowest reading point of the existing
scale on the measuring tube (1).
2. Pull current scale off.
3. Stick new scale on so that the marking on the measuring
tube matches with the lowest reading point (2).
5.4 Performing the hydrostatic test
Perform hydrostatic test using neutral medium, e.g. water.
1. Pressurize the device, ensuring
– Test pressure < 1.5 x PN(Nominal pressure)
– Test pressure < PN+5bar
