7750 Series Installation Instructions
FLOW METER LIMITED WARRANTY
Meters are warranted against defects in materials and workmanship to the original user for a period of
thirteen (13) months from the date of factory shipment, provided the meter is installed, operated and
maintained in accordance with King Instrument Company’s instructions and recommendations.
This warranty does not apply if failure is caused or contributed to by any of the following: improper
handling, improper storage, abuse, unsuitable application of the product, lack of reasonable and
necessary maintenance, use exceeding suggested pressure and temperature maximums, improper
packaging for return, or repairs made or attempted to be made by anyone other than King Instrument
Company, Inc.
KING INSTRUMENT COMPANY, INC. MAKES NO WARRANTY AS TO THE FITNESS OF ITS PRODUCTS FOR
SPECIFIC APPLICATIONS.
This warranty is valid for the original end-user only and does not apply to products that have been
damaged or modied. This warranty is non-transferrable and is limited to replacement or repair. The
liability of King Instrument Company arising out of its supply of the products, or their use, shall not in
any case exceed the cost of correcting defects in the products as set forth above.
THIS WARRANTY IS A LIMITED WARRANTY AND SHALL BE IN LIEU OF ANY OTHER WARRANTIES,
EXPRESSED OR IMPLIED, INCLUDING BUT NOT LIMITED TO ANY IMPLIED WARRANTY OR MERCHANT-
ABILITY OR FITNESS FOR A PARTICULAR PURPOSE. THERE ARE NO OTHER WARRANTIES WHICH EXIST
BEYOND THE DESCRIPTION OR FACE HEREOF.
IN NO EVENT SHALL KING INSTRUMENT COMPANY BE LIABLE FOR LOSS OF PROFITS, INDIRECT, CONSE-
QUENTIAL OR INCIDENTAL DAMAGES.
Products should be returned, prepaid, to King Instrument Company, Inc. with proof of purchase. Call
factory for Return Merchandise Authorization (RMA) number and return instructions.
THIS IS IMPORTANT INFORMATION.
READ IT CAREFULLY BEFORE BEGINNING WORK.
1) Inspect meter for damage that may have occurred during shipping.
Report any damage to the container to the freight carrier immediately.
2) Remove any shipping material placed in the inlet and outlet of the
meter. (This is done to prevent damage caused by movement of the
oat during shipping)
3) Make sure your pressure, temperature, uid and other requirements
are compatible with the meter and components.
4) Select a suitable location for installation to prevent excess stress on
the meter which may result from:
a) Misaligned pipe.
b) The weight of related plumbing.
c) “Water Hammer” which is most likely to occur when ow is
suddenly stopped as with quick closing solenoid operated
valves. (If necessary, a surge chamber should be installed. This
will also be useful in pressure start-up situations.)
d) Thermal expansion of liquid in a stagnated or valve isolated
system.
e) Instantaneous pressurization which will stress the meter and
could result in tube failure.
NOTE: In closed thermal transfer or cooling systems, install the meter
in the cool side of the line to minimize meter expansion and contrac-
tion and possible uid leaks at the threaded connections.
5) Handle the meter carefully during installation.
a) Use an appropriate amount of teon tape on external pipe
threads before making connections. Do not use paste or stick
type thread sealing products.
6) Install the meter vertically with the inlet port at the bottom.
7) Meters with stainless steel ttings will support several feet of pipe
as long as signicant vibration or stress resulting from misaligned pipe
are not factors.
8) Meters used in gas service should have suitable valves plumbed in
at the inlet and outlet of the meter. These valves should be no more
than 1-1/2 pipe diameters from the meter ports. The valve at the out-
let should be used to create back pressure as required to prevent oat
bounce. It should be set initially and then left alone. The inlet valve
should be used for throttling purposes. Depending on the installation,
valves may not be essential, but they are most useful in many instal-
lations. Remember: To get a correct reading of ow in gas service, it is
necessary to know the pressure right at the outlet of the meter (before
the valve).

7750 Series Installation Instructions
ADDITIONALLY
• 7750 Series meters are designed for vertical installation only. (Inlet at
bottom, Outlet at top)
• Do not remove or adjust the screws on the back of the indicator
housing.
These screws were positioned during factory calibration and represent
the zero adjustment. If the pointer is set on zero, proceed with installa-
tion. If the pointer is not set at zero, follow these steps:
1) Remove front cover with gasket and shield from
indicator housing.
2) Loosen set screw at the base of the pointer hub.
3) Reposition pointer to zero line.
4) Tighten set screw with a 1/16” allen wrench by holding the
pointer hub and gently tightening the set screws.
5) Replace front cover with gasket and shield on
indicator housing.
CAUTION
Zero is factory set when meter is calibrated. DO NOT loosen screws
that fasten indicator housing to meter body. If indicator housing is
moved, the meter will need to be calibrated.
CAUTION
• 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.
CLEANING
Carefully remove the owmeter from piping system. Remove the
inlet oat stop and outlet oat stop and withdraw oat from top of
meter. All necessary instrument components are now fully accessible
for cleaning with a bottle brush and appropriate mild soap solution*.
Before the meter is reassembled, inspect all parts for damage.
To reassemble, carefully guide the magnetic oat back into the tube.
Reinstall and tighten inlet oat stop and outlet oat stop. Reinstall the
instrument into the plumbing system.
*Do not use cleaning agents that will damage oat or tube.
Meters should be cleaned with a mild soap solution. This will be an
eective cleaner of rust stains. Caution must be used so that materials
of construction are not damaged by cleaning solutions. Hard water
deposits can be removed with 5% acetic acid solution (vinegar).
REPAIR
7750 meters that require repair should be sent to the factory. Please
call for a Return 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 dicult
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 specic application.

7750 SERIES INDUCTIVE SLOT SENSOR
All 7750 Series flowmeters may be fitted with one or two inductive slot
sensors. Inductive slot sensors are 2-wire, DC, low current devices and are
designed to be used with a remote barrier / switch isolator capable of
powering the sensor and providing the desired switching option(s). Barrier /
switch isolators are available with 220VAC, 110VAC or 24VDC supply voltage
requirements, contain single pole double throw (SPDT) relays, and are DIN
rail mountable. (Only 24VDC units are actually powered by the rail.) See
