6. INSTALLATION
6.1 Installation Guidelines
(1) Select a location easy to access for inspection and maintenance.
(2) Avoid a location subject to excessive temperature variation and vibration.
(3) Avoid direct exposure to the sun. (Provide a sunshade or similar protection to keep the meter out of
exposure to direct sunlight if necessary.)
(4) Avoid a location where immersion in water is a possibility.
(5) Select a location free from an atmosphere of corrosive gases.
(6) Location should be free from dust and mist.
(7) Separate at least one meter from sources of electromagnetic induction, such as large transformers
and motors. Also, keep the meter away as far as possible from the sources of severe vibration,
such as motors and pumps.
(8) To ensure consistent and accurate measurement, adhere to the instructions in 6.2 Physical
Orientation, 6.3 Installation Location, 6.4 Installation Guidelines, and 6.6 Installing Proper Pipe
Supports.
(9) The Coriolis flowmeter requires an installation location where pipeline oscillation is held below
0.3G to ensure consistent and accurate measurement. External vibration (including pulsation)
particularly with the same frequency as the drive frequency of the measuring pipe may affect the
measurement. Contact OVAL regarding drive frequency of each model.
(10) Locate the control valve downstream of the flowmeter.
Where cavitation is likely to occur, install the flowmeter at least five meters away.

Hold-down hardware are supplied as standard accessories, but the customer is to furnish the stanchion.
