Installation Instructions
caution
• O-rings should be replaced if meter is disassembled after it has been
in service.
• Do not loosen nuts that fasten indicator housing to metering tube.
If the relationship of meter tube and indicator housing are changed,
meter must be calibrated.
• Serious property damage and great personal injury could occur as
the result of a meter misused or used in an unsuitable application.
repair
7710 meters that require repair should be sent to the factory. Please
call for aReturn Merchandise Authorization (RMA) number and return
instructions.
warning:
Pressure and temperature ratings are based on a study of the engi-
neering data for particular materials used in construction and on the
design of individual models. This information is supplemented by
destructive test results. Meters with stainless enclosures must never be
operated without shields securely in place. Meters exposed to difficult
environments such as those created by certain chemicals, excessive
vibration or other stress inducing factors could fail at or below the
suggested maximums. Never operate meters above pressure and
temperature maximums. It is strongly recommended that all meter
installations utilize an appropriate pressure relief valve and/or rupture
disc. The pressure settings and locations of these devices should be
such that meters cannot be over pressurized. Meter failure could
result in damage to equipment and serious personal injury. Always
use suitable safety gear, including OSHA approved eye protection
when working around meters in service. We are happy to pass along
chemical compatibility information that has been published by the
manufacturer’s of raw materials used in our products; however, this
information should not be construed as a recommendation made by
King Instrument Company, Inc. for a specific application.

in service up to 1,500 psi and 400° F, but always make certain that
materials of construction (including O-Ring material) are compat-
ible with the fluid to be metered at the desired temperature and
pressure.
