Every OVAL Valve Position Indicator is thoroughly tested before it leaves the factory. When received, it should
thoroughly be inspected for indication of rough handling during transit. Necessary handling precautions are
described in this section; read the instructions carefully.
For any inquiries, contact your nearest OVAL designated sales oce.
(1) To safeguard against damage during transit, transport the OVAL Valve Position Indicator to the
installation site in the same container used for transportation from the factory if circumstances permit.
(2) OVAL Valve Position Indicator is adjusted and inspected as an assembly consisting of the meter body,
sensor, pulse generator, etc. It should therefore be handled as an integral assembly.
(3) The register is accurately congured and adjusted. Do not remove its front cover to gain access to its
internal assembly except for reconguration.
If your OVAL Valve Position Indicator is stored for long periods of time upon receipt before installation,
unexpected faulty conditions could result. If a long-term storage is anticipated, take the following precautions:
(1) Keep the OVAL Valve Position Indicator in store in the same shipping container used for transportation
from OVAL if possible.
(2) Place of storage should conform to the following requirements:
★ Free from rain and water.
★ Free from vibration and impact shocks.
★ Temperature and relative humidity in the storage place are at or near room temperature and humidity
(around 25℃ and 65%).
(3) Purge the OVAL Valve Position Indicator that has once been placed in service with clean air, N
2
gas, etc.
to prevent the metered uid from adhering to the meter connections, piping inner walls, housing, etc.
before storage. (Wash clean with suitable detergent if necessary.)
Wash with clean detergent or cleansing uid if necessary.
(4) If storage for extended periods of time is anticipated, good practice is to keep the product in store in the
original conditions at shipment.
To maintain the stated high accuracy and long service life of the OVAL Valve Position Indicator, make sure that
flowrate, pressure, temperature and viscosity are held within the specified. These operating conditions are
stated in the GENERAL SPECIFICATIONS on page 5.
