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 sensor location. The sensor should be
centered above the flume approach section and mounted 8"/203 mm (minimum) above the maximum
liquid level (depending on sensor model).
The sensor should be protected from physical damage and the sensor 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.

TYPICAL SENSOR POSITIONING
FOR FLUMES AND WEIRS
Always refer to the flume or weir manufacturer’s instructions for correct measurement point upstream
from the flume or weir. Location of the sensor is critical for accurate flow measurement.
If manufacturer’s instructions are not available, the following guidelines are generally accepted.
1. PARSHALL FLUME:
Position the sensor at 2/3 Approach as
illustrated above. Sensor height must be
8" (203 mm) or more above the highest
water level.
2. PALMER BOWLUS FLUMES:
Position the sensor at ½ the flume
Diameter upstream from the throat of
the flume. Sensor height must be 8" (203
mm) or more above the highest water
D
level.
3. V-NOTCH WEIRS
3x MAX. HEAD
Position the sensor at 3 x maximum Head
upstream from the weir plate. Sensor height must
be 8" (20.3 cm) or more above the highest water
level.

POSITION
FLOW
WEIR
PLATE
STILLING WELLS
Stilling wells are recommended to reduce the effects of turbulence as water flows through the flume or weir. The
OCF 5.0 sensor is centered over the stilling well. Sensor height must be 8" (203 mm) or more above the highest
water level. The well must be kept clean of sediment and deposits on the side walls.

ZERO POSITIONING OF SENSOR
- Open Channel Flow Applications
Locate the sensor at the position upstream from the throat of the flume or weir plate as recommended by
the manufacturer. A technique for accurate sensor height adjustment is shown:
Page 23
OCF 5.0 Open Channel Flow Monitor
ENCLOSURE INSTALLATION
Locate the enclosure within 20 ft (6 m) of the sensor (500 ft -150 m optional). The enclosure can be wall
mounted with the four mounting screws (included) or panel mounted with Option PM Panel Mount kit
from Greyline Instruments.
Avoid mounting the enclosure in direct sunlight to protect the electronics from damage due to
overheating and condensate. In high humidity atmospheres, or where temperatures fall below freezing,
Option TH Enclosure Heater and Thermostat is recommended. Seal conduit entries to prevent moisture
from entering enclosure.
NEMA4X (IP66) WITH CLEAR COVER
1. Open hinged enclosure cover.

OCF 5.0 Level & Flow Monitors may be ordered factory-configured for 9-32VDC power input.
QUICK BENCH TEST:
Connect Sensor as shown below, then Power. When properly connected figures will show on the large
LCD display. Test operation of the OCF 5.0 by holding the sensor steadily and aiming at a flat, stable
target 12 to 28" (305 to 711 mm) away from the end of the sensor. Allow a few seconds for the OCF 5.0
to lock onto the target before displaying its distance. The OCF 5.0 will now display Range in ft or cm
(factory calibration).
CONNECTIONS:
POWER INPUT: Connect 9-32VDC/0.5 Amps to the + and - terminals. The Power Input GND must be
connected to the nearest Ground pole. A 1 amp fuse in line is recommended.
