CONNECTIONS:
POWER INPUT: The standard model requires AC power input between 100 to 240 VAC 50/60Hz. No
adjustments are necessary for voltages within this range.
Optional DC: 9-32 VDC. Connect to + and - terminals.
Optional Thermostat and Heater modules are available rated for 115 VAC or 230 VAC.
IMPORTANT NOTE: To comply with CSA/UL electrical safety standards, AC power input and relay
connection wires must have conduit entry to the instrument enclosure. Installation requires a switch,
overcurrent fuse or circuit breaker in the building (in close proximity to the equipment) that is marked
as the disconnect switch.
Risk of electric shock. Loosen cover screw to access connections. Only qualified personnel
should access connections.
Note: Use of instrumentation over 40°C ambient requires special field wiring.
Note: User replaceable fuse is 2 Amp 250V (T2AL250V).

UNITS/MODE
From Mode press the and then the or to select Level, Range,
Flow, HRT or Volume.
Range displays distance from the sensor to the target or liquid surface like a
tape measure. Range mode is useful to measure the exact distance
from the sensor to the zero level during calibration.
Level used to measure tank level in linear units, or "Head" in an open
channel for comparison with flow tables.
Volume displays tank inventory in engineering units.
HRT select Horizontal Round Tank mode to calculate and display volume
units in a horizontal round tank.
Flow calculates open channel flow through a flume or weir.
Volume,HRT or Flow gives the additional choice of volumetric units:
ft3 - cubic feet
USG - US gallons
USMG - US million gallons (FLOW only)
IG - Imperial gallons
IMG - Imperial million gallons (FLOW only)
m3 - cubic meters
L - liters
bbl - U.S. oil barrel
Press to store the selection, then to the next menu item and to enter.

CALIBRATION
Press to Calibration and to enter. Use or to position before
each menu item and to enter. When settings are completed press to store and
return to the Calibration menu.
Min Range Distance from the sensor face to highest expected level.
Max Range Distance from sensor to Zero level.
MaxVol For Volume and HRT mode only. Enter the maximum volume of
the vertical or horizontal tank.
Damping Minimum damping allows fast response to level changes.
Increasing damping slows the OCF 5.0's response to level changes
and is ideal to smooth the display and outputs in turbulent
conditions. Damping value is shown in percent (0-99%). Some
experimentation may be required to select the optimum damping
value. A value of 1% is recommended for most applications and for
fast level changes (up to ½ inch/sec - 13 mm/sec).
LOE Time Press and or to change the number of seconds without
receiving an echo before the OCF 5.0 displays ECHO LOSS, and
Control relays change state as calibrated under Relay Parameters.
Factory default is 30 seconds and is recommended for most
applications, Minimum is 1 second and maximum is 99 seconds.

CALIBRATION
- for Open Channel Flow
1. Before starting the calibration determine:
a) MAX RANGE = ____________________
(Maximum range = distance from the Sensor to Zero flow point)
b) MAX LEVEL = ____________________
(Maximum level of flow through flume or weir)
c) MIN RANGE = __________________
(Distance from sensor to Max Level)
Minimum range = MAX RANGE - MAX LEVEL
(must be at least 8" / 20.3 cm depending on sensor model).
2. Check the maximum range with the sensor installed by:
a) When liquid is at zero level press to view the Range reading in the
Status menu. Use this range measured by the OCF 5.0 as the Max
Range setting.
or
b) Carefully measure distance from sensor to zero level with a tape measure,
and use this measurement as the Max Range setting.
NOTE: The OCF 5.0 will not detect targets beyond user entered Max Range.

SENSOR MOUNTING/LOCATION
- Open Channel Flow Applications
Each sensor is equipped with a 3/4 inch isolation coupling which MUST be used in your installation. A
threaded nipple or length of conduit may be used to position the sensor at the desired height. The sensor
should be hand-tightened by turning the sensor stem only. DO NOT use a wrench and do not over
tighten.
IMPORTANT: Follow the flume manufacturer’s directions for transducer location. The transducer
should be centered above the flume approach section and mounted 8"/203 mm (minimum) above the
maximum liquid level (depending on sensor model).
The transducer should be protected from physical damage and the transducer cable should be routed in a
separate metal conduit.
Because the sensor is equipped with a temperature sensor, it should be shielded from direct sunlight.
Use the PVC “isolation coupling” supplied with the sensor and hand-tighten the sensor/coupling
assembly onto your mounting stand. Do not clamp directly to the sensor or to the isolation coupling.
