Industry standards are established by the American
Water Works Association. These standards assure
the homeowner that the water will be accurately
and fairly measured. Johnson Utilities uses positive
displacement type meters which provide the most
advanced technology available for water flow measurement
in residential and light commercial applications.
Our meters are manufactured to rigid design specifications
to ensure consistent high product quality.
are so exact that pistons and measuring chambers
manufactured years apart can be exchanged with
no resulting difference in measurement accuracy.
The meters and their components undergo a variety
of tests throughout the manufacturing process.
The manufacturer maintains an extensive range
of testing facilities and laboratories. Testing
and quality assurance encompasses a number of
on-site facilities. At these sites our supplier
conducts continuing tests and assurances of their
materials, chemicals and metallurgy, as well as
high accuracy calibration and endurance tests.
evaluation is also done using equipment such as
an electron-beam microscope, which is capable of 3,000x
magnification; a Weatherometer, which is able to simulate
any environment from desert to rain forest, and
other specialized instruments. Meters are manufactured
on modern equipment using a Statistical Process
Control system to ensure all components are made
to rigid design dimensions. This program requires
critical part dimensions to be recorded and monitored
to confirm that all the machine operations are
producing good parts and that no negative trends
manufacturer uses only top grade materials to
ensure the best product quality. All materials
are thoroughly tested to adhere to engineering
specifications. For example, the piston and chamber
materials are made of a proprietary blend of synthetic
resins, specifically formulated to reduce friction
and resist wear. Additionally, only high quality
sand cast meter bodies are utilized. Using 81% copper content sand cast bodies helps minimize
head loss when the meter is placed in service.
These main cases are all machined and go through
a vibratory deburring to further perfect the casing.
features include a tamper resistant elliptical head
design, hermetically sealed registers and an oscillating
piston design to minimize friction in the piston
The comprehensive training of a skilled work force,
combined with the extensive use of automated work
cells and robotics, allows the manufacturer to
maintain high quality to meet customer demand.

new water meter is installed in the water service
line of a home to accurately measure the water
consumed. The manufacturer guarantees the accuracy
of the meter when the utility company purchases
it. Our meters meet and usually exceed exacting
standards set by the A.W.W.A.
Utilities uses only positive displacement meters.
It is the meter standard for residences. The positive
displacement meters contain a predetermined chamber
with a fitted disc or piston. Each time the chamber
fills and empties, a predetermined amount of water
is displaced as the disc or piston makes one rotation.
The action of the piston is transferred to the
meter by the use of gears or magnetic drivers.
Once precisely calibrated by the manufacturer,
the meter will continue to register accurately
as long as the piston makes the correct number
of cycles for each gallon passed through the meter.
Under ordinary working conditions, for example,
potential suspended matter could cause a bind
between the measuring element and its chamber
causing it to slow down, which result in
under-registration of the meter. Exposure to materials
in suspension, excessive wear, temperature extremes
or corrosion could cause the meter to under-register; however in no case will the meter be caused to over-register.
installed residential water meter cannot over-register.
Water meters fail by slowing down and eventually
stopping. In our meters, the motion of the element (the piston) is transmitted by a system of gearing
to the register, which records the flow of convenient
units of measurements such as gallons. The register
reading is thus dependent on the number of operations
of the piston. The reading is a true measure of
usage when the meter is accurately calibrated.
This calibration takes place at the manufacturer’s
do arise in which the homeowner questions the
accuracy of the water meter. We explain how meters
are manufactured, how they operate and how they
are read. We make every effort to inform our customers
about a subject few are familiar with.
The most common time for questioning accuracy
is when a new meter is installed to replace an
old, worn-out meter. The higher accuracy level
often results in a higher reading for the user.
The possibility of old or worn-out meters has
not been in question for Johnson Utilities. The
time interval for replacement meters is based
on local conditions and the amount of consumption.
Normally this is a 10 to 15 year period.
We are proud of our company and remain
committed to providing high
quality service. We look forward to growing with
