Electromagnetic flowmeters | Full-bore flow sensors 2 Mechanical Installation

Fig. 2.6 Within Temperature Limits
Caution. Ensure the flowmeter is operated within its specified temperature limits. Use flange seals
made from a material that is compatible with the fluid and fluid temperatures as required.
Fig. 2.7 Straight Pipe Requirements
Note. Ensure the flow direction in the pipeline corresponds to the identification plate. The flowmeter
measures the flowrate in both directions. Forward flow is the factory setting. Experience has shown that,
in most installations, a straight upstream section 3 x pipe diameters in length and a straight downstream
section 2 x pipe diameters in length are sufficient. However, wherever possible, straight upstream and
downstream sections 5 x 2 pipe diameters in length are recommended.

Note. For accurate and reliable operation, install the flowmeter sensor in a position where it will be
completely full when in operation. The flowmeter will operate when not full, but indicated readings will not
be accurate.
