Board Meeting June 3, 2009
RFP Response from Vulcan, Datamatic, Ferguson, Elster AMCO
Clarifications for the May 20th Board Meeting
1. Benefits of 2-Way Communication
a. Update and maintain Water Conservation Schedules
b. On-demand reads
c. Can change interval from hour, to half hour, to 15 minutes from the host
computer
d. Operate other devices such as remote shut off valves, distribution leak
detection, SCADA systems and other devices
e. The MOSAIC's firm can be updated from the Host computer, meaning
how the device works, new meter register protocols can be download to
all MOSAIC endpoints (from the very oldest installed in the system to very
newest on the shelf). This virtually eliminates obsolescence
2. Field Replaceable Battery
a. Extends the life of the endpoint to match the life of the meter or beyound
b. Reduces or eliminates the need to upgrade the system in 15 years
because the endpoints and the system will not become obsolescent. The
firmware is upgraded
3. Product Cost vs. Labor Cost, the overall cost of either system is similar
a. Vulcan's response has higher labor cost, lower product cost. The labor is
a one time cost; the product cost is for the life of the system. All new
installations and replacement meters and endpoints will cost the Truckee
Donner over 22% more.
b. If the labor and the product were separated into different contracts by
Truckee (like the City of Folsom who used an outside consultant, the City
of Sacramento, the City of Fresno who used two different consultants)
how would the board view one technology over the other. The price for
the Aclara system would be $1,838,000, the cost of the Datamatic system
would be $1,489,000, a savings of$349,000 or 19%.
4. 500 existing commercial meters
a. The Aclara system will not deliver the same quality of data when attached
to the Sensus meters or the Badger meters. Datamatic will provide the
same level of data regardless of meter.

Wiegand effect('ve•gannt)(pronounced wee-gand)
The Wiegand effect is named after its discoverer,John R.Wiegand.
Overview
The egandfec1.1't>s s emgrahg plienomez�oi in a special alloy wire that is processed in such a way as to
create two distinct magnetic regions in the same homogeneous piece of wire,referred to as a shell and a core.It
occurs when such a specially processed wire(a"Wiegand wire")is moved past a magnetic field.The two distinct
magnetic regions react differently to any applied magnetic field:the shell requires a strong magnetic field to
reverse its magnetic polarity,whereas the core will revert under weaker field conditions.When the shell and core
b
change to different polarity orientations,the"t�egand pulse is g�e? �and is sensed Y a pickup coil(the
reader).
The polgrily of the wire will very rapidly shift and generate strong,short(—10 µs)electrical pulses without any
additional external power being supplied.This is known as the"Barkhausen jump".The Barkhausen jump can be
detected by a coil wrapped around the material,when the small amount of voltage described above is generated.
Uses in sensor technology
Sensor based on the proprietary and patented Wiegand effect require only a few simple components:a short
length of Wiegand wire,a sensing coil,and alternating fields,which are generally derived from small permanent
magnets. Sensors of this type can be used across a wide range of conditions The Wiegand effect occurs from-80
degrees Celsius to 260 degrees Celsius Wie d„e„ff.ect sensors are used in.water,,gas,aaid electric meters;for
elec#rinxcexg They also have many automotive applications such as antilock braking,speed sensing,and
position indicators.They have been used in anemometers and other wind speed applications,machine controls,
shaft speed sensing,and numerous rotational counting applications.Wiegand wires are also used in access control
systems.
wu
Due to the complexity ofma iufai a ang the "Iegand ,Wiegand cards are virtually impossible to duplicate
and remain one of the most secure access control technologies.
Wiegand wire is produced by cold-working a 0.010 inch(1 millimeter)diameter ferromagnetic wire made of
Vicalloy,a mixture of cobalt,iron,and vanadium.The cold-working process consists of increasing amounts of
twist and de-twist of the wire under applied tension in several steps.The wire is then age-hardened to hold in the
tension built up during the cold-working process.This procedure causes the Wiegand wire to have a soft magnetic
center,the core,and a work-hardened surface with a higher magnetic coercivrtv the shell.When an alternating
magnetic field of proper strength is applied to the Wiegand wire,the et�re"s magnetie field syill sw�tcl�.p4 anti'.
then reverse_a$a ,causing a Wiegand pulse to be generated.This is called the Wiegand effect.
The patented cold-working process that produces the Wiegand wire permanently locks in the ability to exhibit
Barkhausen jump discontinuities in the material.To achieve magnetic switching,the wire is put in the presence of
alternating longitudinal magnetic fields.The resultant hysteresis loop contains large discontinuous jumps known
as Barkhausen discontinuities that occur due to shell and core polarity switching.
One type of noncontact magnetic sensor does work at zero speed yet requires only a passive pickup coil that has
two connections.These devices,which employ the Wiegand effect,use HID Corp's proprietary technology and
are relatively uncommon in rotary-motion sensing.Strictly speaking,Wiegand-effect rotary-motion sensors aren't
gear-tooth sensors,because gear teeth play no role in their operation.For a Wiegand sensor to measure its angular
position or velocity,a rotating wheel must contain multiple permanent magnets around its periphery.The magnets'
north-south axes must parallel the wheel's axis of rotation,and the wheel must contain an even number of magnets
with alternating north-south orientation.The pickup coil,mounted near the wheel's periphery,consists of specially
manufactured wire that produces an approximately 10-µsec pulse whenever the impinging magnetic field's
polarity reverses,regardless of how slowly.

RE: CSLB File#2072-08
Water Meter Installation
Dear Mr. Dietl:
Thank you for your correspondence originally sent to Board Member Lisa Miller regarding your
concern that the board had incorrectly been advising agencies and cities that the
C36/Plumbing classification was appropriate for the installation of water meters. Your letter
was referred to me for reply.
First, let me clarify that classification determinations are based solely on the information
provided by the person inquiring at the time. Occasionally, pertinent information related to the
issue is omitted from the initial request, which can affect the accuracy of the determination.
After further review of additional documentation which was submitted related to the specific
issue you raised, the board has reconsidered its original position. Because the C36/Plumbing
classification specifically covers the piping from the property owner's side of the utility meter to
the structure or fixed works only, it appears the C36 is not the appropriate classification for this
speck job. Based on the information now before us, the most appropriate classification for the
complete installation of water meters would be the A/General Engineering classification.
apologize for the confusion this matter may have caused. Should you need further
assistance, please contact me at (916) 255-3964.
Sincerely,
ImaAZcuxrc2
