FLOW RANGE
Acceptable for each transmitter unit is
the same as that for the meter to which
the unit mounts.
MATERIALS
Used in construction are chosen for their
durability and immunity to the corrosive
effects of atmospheric moisture and the
liquids measured by the meter assem-
bly.
OUTPUT SIGNAL
Current signal: 4-20 mA sourcing type
(with loop impedance of 175
Ω
to
1075
Ω
), true two wire with external
power supply.
Pulse rate: two wire scaled pulse rate
output. (Customer specified pulse
rate, 600 PPM max.) The maximum
recommended distance for pulse output
transmission is 5000 feet.
Pulse Output Ratings
Maximums are for signals between P2
and P1
Voltage: 18 VDC
Current: 60 mA DC
Power dissipation: 100 mW
Note: Unit utilizes an open collector
transistor output. 35 VDC reverse volt-
age polarity protection.

OPTIONAL EQUIPMENT
Includes non-reversing ratchet, special
outputs (consult factory for special ap-
plications).
ORDERING INFO

gears and type of dial on totalizer that is
going to be replaced.
III. UNPACKING
. When unpacking the transmitter, any damage due
to rough or improper handling should be immediately reported to
the transportation firm and McCrometer. If for any reason, it is de-
termined that the unit or parts of the unit should be returned to the
factory, please contact McCrometer for clearance prior to shipment.
Each unit must be properly packaged to prevent any further dam-
age. The factory assumes no responsibility for equipment damaged
in return shipment due to improper packaging. Proper paper work
must be enclosed with any returned material.
The shipping carton contains the following items:
Model TR15 or TR16 ......................................................................1
Base O-Ring
1
Mounting Screws 4
Vertical Shaft Clevis ......................................................................1
Clevis Coupling 1
Operation and Maintenance Manual .............................................1
IV. INSTALLATION
of transmitters is normally done at the factory when
the meter is assembled, but may be made in the field with the meter
stopped (i.e. no flow). Depending upon what situation exists, various
steps for installation apply and the procedures are outlined below.
1. REMOVE
the existing totalizer or indicator or transmitter by
removing all the mounting screws and lifting the unit off the meter
head.
2. CLEAN METER HEAD
of all dirt, glue, gaskets and other foreign
material.
3. TOTALIZER DRIVE MAGNET
must be removed from the vertical
shaft tip of meters equipped with a totalizer so that the transmitter
drive clevis (#35) can be installed on the vertical shaft tip. The total-
izer drive magnet can be removed by loosening the set screw in the
side of the magnet hub and sliding the assembly off the vertical shaft.
4. INDICATOR DRIVE GEAR
must be removed from the vertical
shaft tip of meters equipped with indicator-totalizers so that the
transmitter drive clevis (#35) can be installed on the vertical shaft tip.
The indicator drive gear can be removed by loosening the set screw
in the side of the gear hub and sliding the assembly off the vertical
shaft.
5. TRANSMITTER DRIVE GEAR
must be removed from the vertical
shaft of meters equipped with an old style McCrometer Model TR01
or TR06. The transmitter drive gear can be removed by loosening the
set screw in the side of the gear hub and sliding the assembly off the
vertical shaft.
6. VERTICAL SHAFT
assembly must be removed from the meters
equipped with an old style McCrometer CN06 indicator, TR01 or TR06
transmitter (.100” dia. vertical shaft tip) and replaced with a vertical
shaft that has a 3/16” diameter tip. Vertical shaft removal can be ac-
complished by removing the two vertical shaft collar bearing mount-
ing screws in the meter head and pulling the vertical shaft directly out
of the top of the meter. Remove the vertical shaft collar and bearing
assembly from the vertical shaft by loosening the set screw in the side
of the collar and sliding the assembly off the vertical shaft.
7. REPLACEMENT VERTICAL SHAFT
for meters with
old style McCrometer models CN06 indicators, TR01 or TR06
transmitters, should be inspected to be sure it is not bent
or damaged. Install the vertical shaft collar and bearing
assembly on the new (3/16” diameter tip) vertical shaft,
