7459 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 recom-

mendations.

This warranty does not apply if failure is caused or contributed to by any of the following: im-

proper handling, improper storage, abuse, unsuitable application of the product, lack of reason-

able 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, EX-

PRESSED 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,

CONSEQUENTIAL 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) Make sure your pressure, temperature, uid and other requirements

are compatible with the meter (including o-rings.)

3) 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.

4) 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.

b) Over tightening of plastic connections may result in tting

damage.

5) Install the meter vertically with the inlet port at the bottom.

6) Connections: Fittings are fully rotatable by loosening the tting

retainer screws during installation. Make sure tting retainer screws

are tightening after adjustment of tting

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 with plastic ttings must be installed so that ttings are not

made to support any part of the associated plumbing. In addition,

meter frame should be fastened to bulkhead, panel or column.

9) 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).

CAUTION

• O-rings should be replaced if meter is disassembled after it has been

in service.

• 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 4

screws on each side holding the side plates on. Remove the 4 screws

on each side holding the front and rear shields on. Remove the side

plates and shields. Carefully remove the glass meter tube from the end

ttings. Be sure to not let the internals fall out. Use caution when re-

moving the glass meter tube. Do not allow oat to fall out. Float dam-

age may result in inaccuracy. 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. O-rings should be replaced during meter maintenance

and cleaning.

*Do not use cleaning agents that will damage oat, tube or o-rings.

To reassemble, install the glass meter tube back onto the end ttings.

Reinstall the side plates and shields. Tighten the 4 screws on each side

and front and back. Reinstall the instrument into the plumbing system

after removing the old teon tape (with a wire brush) and replacing

with fresh teon tape.

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

7459 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.
