INTRODUCTION
WARNING
POTENTIAL ELECTROSTATIC CHARGING HAZARD. THE NONMETALLIC PART OF THE ENCLOSURE MUST BE CLEANED
WITH A DAMP CLOTH TO ELIMINATE THE RISK OF STATIC ELECTRICITY.
The transit time meter measures volumetric flow and heating/cooling energy rates in clean liquids as well as those with small
amounts of suspended solids or aeration, such as surface water or sewage. The ultrasonic flow and energy meters clamp onto
the outside of pipes and do not contact the internal liquid.
The meter is available in two versions:
• A flow meter for water delivery, sewage, cooling water, alcohols, chemical
• A heating/cooling energy flow meter used in conjunction with dual clamp-on RTDs for temperature measurement—ideal
for hydronic process and HVAC applications
Transit time flow meters measure the time difference between the travel time of an ultrasound wave going with the fluid
flow and against the fluid flow. The time difference is used to calculate the velocity of the fluid traveling in a closed-pipe
system. The transducers used in transit time measurements operate alternately as transmitters and receivers. Transit time
measurements are bi-directional and are most effective for fluids that have low concentrations of suspended solids and are
sonically conductive.
Figure 1: Meter operation
An ultrasonic meter equipped with heat flow capabilities measures the rate and quantity of heat delivered or removed from
devices such as heat exchangers. By measuring the volumetric flow rate of the heat exchanger liquid, the temperature at the
inlet pipe and the temperature at the outlet pipe, the energy usage can be calculated.
By applying a scaling factor, this heat flow measurement can be expressed in various units (Btu, Watts, Joules, Kilowatts
and others).

INSTALLATION
Overview
Each of the installation steps that follow is explained in detail on page 11 through page 12 . The actual installation
procedures differ slightly, depending on whether the transducers are fixed or adjustable.
If the transducers are fixed, you will:
1. Install the transducers.
2. Install the transmitter.
3. Wire the transmitter.
4. Program the meter.
If the transducers are adjustable, you will:
1. Install the transmitter.
2. Wire the transmitter.
3. Set up the meter (select the optimum transmission mode, enter the site information, and enter the uid and
pipe properties).
4. Install the transducers.
5. Complete the meter programming.
Installation Considerations
Mount the transmitter in a location:
• Where little vibration exists.
• That is protected from corrosive fluids.
• That is within the transmitters ambient temperature limits:
–4…140° F (–20…60° C); relative humidity 0…85%, non-condensing; altitude 2000 m max.
• That is out of direct sunlight. Direct sunlight may increase transmitter temperature above the maximum limit.

Figure 23: Wiring connections
OTE:NSubmersible transducer cables are larger diameter. Each cable requires a separate conduit hole. The standard yellow
cable and high temperature cables are small enough to use a single cable gland with a 2-hole grommet.
OTE:N Transducer cables have two wire-color combinations. For the blue and white combination, the blue wire is positive
(+) and the white wire is negative (–). For the red and black combination, the red wire is positive (+) and the black
wire is negative (–). The transducer wires are labeled to indicate which pair is upstream or downstream.
1. Guide the transducer terminations through a conduit hole in the bottom of the enclosure.
2. Secure the transducer cable with the supplied conduit nut (if exible conduit was ordered with the transducer).
3. Install the ferrite to the cable:
a. To open the ferrite, pull the fastener away from the
body of the ferrite.
b. Wrap the cable tightly around half of the ferrite and
place the cable into the groove.
c. Snap the ferrite shut.
4. The terminals within the transmitter are screw-down barrier terminals. Connect the wires at the corresponding screw
terminals in the transmitter. Observe upstream and downstream orientation and wire polarity. See Figure 24.

Power
Connect power to the screw terminal block in the transmitter.
• Low voltage power can use any available conduit hole in the enclosure.
• Line voltage AC power must use the right conduit hole, which is aligned with the terminal block on the AC power board.
• Use wiring practices that conform to local and national codes such as The National Electrical Code Handbook in the U.S.
ANY OTHER WIRING METHOD MAY BE UNSAFE OR CAUSE IMPROPER OPERATION OF THE TRANSMITTER.
OTE:N This transmitter requires clean electrical line power. Do not operate this transmitter on circuits with noisy
components (such as fluorescent lights, relays, compressors, or variable frequency drives). Do not use step-down
transformers from high voltage, high amperage sources. Do not to run signal wires with line power within the same
wiring tray or conduit.
9…28V DC Power
The transmitter may be operated from a 9…28V DC source, as long as the source supplies a maximum of 8 Watts of power.
Connect the DC power to 9…28V DC In, power return, and chassis ground, as in Figure 25.
OTE:N DC-powered transmitters are protected from major catastrophe with an internal 2.0 Amp slow-blow fuse. If this fuse
is blown, replace the transmitter or return it to the factory for repair.
IMPORTANT: A Class II DC power supply is required.

Mains Power
IMPORTANT:The measuring device does not have an internal circuit breaker. For compliance with IEC 61010-1, a switch in close
proximity to the transmitter is required so that the power supply line can be easily disconnected from the mains.
The transmitter may be operated from 90…250V AC, 47…63 Hz, 24VA maximum power source.
OTE:NMains AC-powered transmitters are protected with 1A, 250V AC, 5×20 mm, slow-blow, field-replaceable fuse.
WARNING
TO PREVENT SHORTING OUT THE MAINS AC POWER, YOU MUST REPLACE THE TERMINAL BLOCK COVER ON THE AC
MODULE AFTER WIRING THE POWER.
Remove the terminal block covers before wiring and replace them after wiring:
1. Grasp the sides of the cover and gently pull it up.
2. Insert wires into the slots on the cover and screw them down to secure.
