When it comes to flow...we’re instrumental.

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 flowmeter from piping system. Remove the
threaded outlet plug and withdraw the float from the top. All neces-
sary 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.
To reassemble, carefully guide the magnetic float back into the tube.
Reinstall and tighten top plug in appropriate port. Reinstall the instru-
ment into the plumbing system after removing the old teflon tape
(with a wire brush) and replacing with fresh teflon tape.
*Do not use cleaning agents that will damage float, tube or o-rings.
Meters should be cleaned with a mild soap solution. This will be an
effective 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

7100 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 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.

Carefully remove the flowmeter from piping system. Remove the threaded outlet

plug and withdraw the float from the top. 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.
To reassemble, carefully guide the magnetic float back into the tube. Reinstall

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

-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.

1) Inspect meter for damage that may have occurred during shipping.

Report any damage to the container to the freight carrier immediately.

This is important information. Read it carefully

before beginning work.

2) Make sure your pressure, temperature, fluid and other

requirements are compatible with the meter including o-rings (where

applicable).
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 flow 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

contraction and possible fluid leaks at the threaded connections.

4) Handle the meter carefully during installation.

a) Use an appropriate amount of teflon tape on external pipe

threads before making connections. Do not use paste or stick type

thread sealing products.

5) Install the meter vertically with the inlet port at the bottom.
6) Meters with stainless steel fittings will support several feet of pipe

as long as significant vibration or stress resulting from misaligned pipe

are not factors.

Meters are not specifically recommended for service other than

water or air. The user must determine meter suitability for use

with other fluids.

ADDITIONALLY:

-7100 Series meters are designed for vertical installation only. (Inlet at

bottom, Outlet at top)

-Do not remove or adjust the screws on the side of the indicator

housing. These screws were positioned during factory calibration and

represent the zero adjustment. If these screws are loosened and the

indicator housing is moved, the scale will be out of accuracy.

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.
