ISSUED FOR CONSTRUCTION January 15, 2018
METERS AND GAGES FOR HVAC PIPING 230519 - 9
1. The meter must be a clamp-on design that mounts
externally on the pipe with no liquid contact.
2. The meter must utilize the transit-time flow measurement
technique and employ the use of TWO microprocessors and
have the ability to monitor TWO independent flow and
channels simultaneously (second channel optional with the
ability to be field retrofitted). Two microprocessors
allow for faster speed of response, better accuracy in
difficult applications, multiple channel capability &
flexibility for multiple output formats.
3. The meter must be supplied with the ability to employ an
alternate Doppler measurement technique for liquids with
high air or solid content with no additional hardware.
This must be an integral standard function without the
need for additional sensors or hardware.
4. The meter must have a flow transducer encased in
stainless steel with an integral 13 ft (minimum length)
armored stainless steel jacketed TRIAX cable. The use of
COAX cable and BNC cable connections will not be
acceptable. Non-stainless cable & sensor electrical
connectors have been known failure points and are not
acceptable.
5. All transducer markings and identification must be laser
scribed and solvent resistant. The use of adhesive
labels for transducer identification will not be
acceptable. This allows for reliable hardware tracking
after installation.
6. All calibration and transducer data must reside in a non-
volatile memory chip located in the transducer junction
box or flow meter. This allows for any future changes or
factory support work (sensor calibration or replacement)
without the need to send out the display-transmitter.
7. The meter must have the ability to automatically
recognize the transducers when connected. Programming of
the transducer type into the meter will not be
acceptable. This allows for a more reliable performance
with less operator input.
8. The meter shall be capable of outputting multiple 4-20ma,
Voltage 0-1v or 0-10v, high precision frequency 0-1kHz or
0-10kHz galvanically isolated, RS-232, RS-484, Modbus
RTU, BACnet TCPIP, Modbus IP, BACnet IP, binary output
pulse or alarm for relay total and meter status. The
meter shall be capable of field enhancements to change or

add to the originally supplied outputs; returning the
meter to the factory for these changes is not acceptable.
9. The meter shall have the ability to status alarm for
conditions of fault, empty pipe fault, flow direction,
sound velocity limit, flow velocity limit.
10. The meter shall have the ability to set the 4-20ma to a
settable status condition (i.e. 2ma for an alarm
condition). The specific setting of the 4-20 signal
during an alarm condition will be defined by the college
before the equipment commissioning.
11. The meter shall have RS-232 output and internal memory
with a minimum storage of 100K data points. This allows
for data analysis history when troubleshooting.
12. The flowmeter electronics shall be housed in a NEMA 4X
enclosure and must have the ability to indicate flow
rate, flow velocity, mass flow, total flow, signal
strength, signal quality, liquid sonic velocity, Reynolds
regime (laminar/turbulent/transition).
13. Clamp on Sensors to be mounted & held in place by 304 SS
band straps. Other mounting methods are not allowed. A
short profile is needed to allow the insulation & vapor
barrier to be completely repaired by the supplier after
commissioning.
C. Performance and accuracy requirements:
1. Standard flow sensors must hold accuracy specification
(stated below) for process temperatures from 0 to 298 F.
The metering electronics must have the ability to operate
HIGH TEMPERATURE flow sensors capable of measuring liquid
flows at temperatures up to 750oF.
2. The transducers are to have the ability to be coupled
using permanent coupling pads (grease is NOT acceptable).
Permanent couplant pads eliminate the need for sensor
maintenance (ie, recoupling the sensors by reapplying
couplant). Pipe insulation is to be permanently repaired
& vapor sealed after initial installation &
commissioning.
3. The flow transducers must have a multi-point wet flow
calibration certificate accredited from an international
standards agency with an accuracy of better than 0.6%.
Only one flow sensor PN must be able to measure chilled
water in CS or Cu pipes from 2.5 to 18” OD. This allows
for a minimum of spare parts.

ISSUED FOR CONSTRUCTION January 15, 2018
METERS AND GAGES FOR HVAC PIPING 230519 - 11
4. The meter must be of a type that requires NO zero
calibration. The zero calibration must be factory pre-set
automatic without the need for zero check/calibration
after installation. There must not be any zero drift
mechanisms (i.e. temperature change related drift) as the
meters can NOT be installed with any low-flow cutoff or
“deadband”. Automatic integral flow sensor temperature
compensation is required to eliminate the flow
measurement drift due to temperature variations; this
allows for improved measurement accuracy & low-end
sensitivity below 0.25 fps. The method for temperature
compensation corresponds to ANSI/ASME MFC-5.1-2011.
5. The meter must also provide automatic Reynolds number,
liquid sonic velocity compensation, and have built in
liquid tables for automatic sound velocity, viscosity,
and density settings.
6. The meter must have the ability to have dynamic
(automatic) compensation for changes in viscosity and
density.
D. Energy Management:
1. Because the college will likely need the measurement of
Energy (BTU/Tons with temperature for supply & return
pipes) in the future, the following will apply to the
meters being supplied.
2. The meter must be able to be field retrofitted to be able
to measure energy along with flow.
3. The meter must be able to be field retrofitted to have
inputs for 4 wire RTD’s and have a capability of
accepting either 100 or 1000 ohm platinum RTD pairs. Two
or three wire designs will not be acceptable. The
temperature sensors & circuit must have a measurement
accuracy of .03oF over a temperature range of 32 oF to
400 oF. RTD’s must be Rated IEC 751 Class A and provided
as matched pairs to an accuracy of 0.03oF. Four wire
sensors allow for longer sensor cables without a loss in
performance. The temperature accuracy is critical in
properly measuring energy rate.
4. The meter must have the ability to indicate BTU rate, Ton
rate, flow rate, mass flow, total BTU’s, total tons in
addition to the units above.

5. The energy (BTU/Tons) calculation must meet standard
EN1434 for proper accuracy. Other methods are
unacceptable.
E. Support Requirements:
1. Standard hardware lead times must be 3 weeks ARO.
Expedited delivery in less than 3 business days for all
hardware items is required for any emergencies. Factory
phone support must be available 24 hours a day for both
weekdays & weekends. A local factory trained & approved
service technician needs to be located within 20 miles of
the installation site to provide field support. This
allows for expedient, economical support.
2. All hardware to carry a warranty for 12 months after
installation or 18 months after shipment from the
factory, whichever occurs first. Warranty covers both
hardware repair/replacement & factory labor.

(Channel A). The pipe is 6” CS sch 40. Flow sensors
are required to be rated to 266 F media & surface
temperature for both flow accuracy temperature
compensation & environmental protection.
1) This will require sensor extension cables past
13 ft. It is estimated for the Chilled Water
measurement that the total length of sensor
extension cable will not exceed 100 feet. A
sensor cable junction box and 100 feet of
sensor extension cable is to be supplied.
d. Measurement of the flow rate of Steam Condensate

random checks verifies that testing and balancing are
complete and accurately documented in the final report,
request that a final inspection be made by Architect.
2. The TAB contractor's test and balance engineer shall
conduct the inspection in the presence of Architect.
3. Architect shall randomly select measurements, documented
in the final report, to be rechecked. Rechecking shall
be limited to either 10 percent of the total measurements
recorded or the extent of measurements that can be
accomplished in a normal 8-hour business day.
4. If rechecks yield measurements that differ from the
measurements documented in the final report by more than
the tolerances allowed, the measurements shall be noted
as "FAILED."
5. If the number of "FAILED" measurements is greater than 10
percent of the total measurements checked during the
final inspection, the testing and balancing shall be
considered incomplete and shall be rejected.
