3 Installation

3.1 Mechanical process connection

Caution!
The following requirements must be strictly adhered to, or the flow rate transmitter
or the system will be damaged:
- A suitable process port must be available on the system to connect the instrument
- Check the port size
- Check the engagement depth
E
- Use appropriate sealing material (liquid sealants will damage the flow rate transmitter, if
they flow into it)
- Seal correctly

3.2 Ambient conditions

- The flow rate transmitter must not be used as a load-bearing part in pipework.
- The medium must not contain solid particles. Magnetic particles accumulate on the
magnetic float and impair the function.
- Check the compatibility of corrosion and frost protection before use.
Warning!
The following requirements must be complied with, otherwise the function of the
flow rate transmitter will be impaired and the measurement results distorted:
- External magnetic fields will affect the measurement. Ensure sufficient distance from
magnetic fields (e.g. electric motors)!
- Pipes, process ports or mounting brackets in ferromagnetic material will affect the
magnetic field of the flow rate transmitter. Ensure there is a minimum distance of
100 mm to such materials (e.g. steel).
- Changes in cross-section, T-pieces or elbows in the pipe affect measurement accuracy.
Install a calming section of 10 x DN before the instrument and 5 x DN after the
instrument . Never reduce the pipe diameter just before the instrument!
- When used with fluids, the instrument must be vented by suitable means
