SAFETY INSTRUCTIONS

1. Depressurize and vent system prior to installation or removal.

2. Confi rm chemical compatibility before use.

3. Do not exceed maximum temperature/pressure specifi cations.

4. Wear safety goggles or faceshield during installation/service.

5. Do not alter product construction

6. If this equipment is used in a manner not specifi ed by the manufacturer, the protection provided
by the equipment may be impaired.

7. This device is not approved for use or installation in hazardous locations.

Description

The Omega FPB Series Paddlewheel Flowmeter offers low fl ow, low power and high resolution with output options for a fl ow switch,
pulse divider, or 4-20 mA. This unit can be confi gured on-site directly through the built-in user interface and LCD display. During
normal operation the display is not visible.

• The 4-20 mA model provides a blind current loop output.

• The Flow Switch model uses a single relay (mechanical or solid state) for Hi or Lo alarm operation.

• The Pulse model uses a single relay (mechanical or solid state) and has two selectable operating modes:

• The Divider mode scales the paddlewheel frequency down to accommodate low frequency input devices.

• In Total mode, the Pulse Model becomes a traditional pump pulser, able to output one pulse per a set volume of fl uid.

Intended Use: This product is intended for use in industrial water treatment

and waste water treatment applications where the chemical content and the fl uid
temperatures are consistent with the specifi cations listed herein.

This device is not approved for use or installation in fl ammable liquids.

Location of Fitting

Recommended sensor upstream/downstream mounting
requirements

Select a location with suffi cient length of straight
pipe immediately upstream of the sensor.

Locating the sensor in a trap or where the fl ow is
upward helps to protect the sensor from exposure
to air bubbles when the system is in operation.

These confi gurations are not recommended because
it is diffi cult to keep the pipe full.

Sensor Mounting Position

• Horizontal pipe runs: Mount sensor in the upright (0°) position for best performance. Mount at a
maximum of 45° when air bubbles are present (pipe must be full). Do not mount on the bottom of
the pipe when sediments are present.

• Vertical pipe runs: Mount sensor in any orientation, however, downward fl ow is not recomended.
Upward fl ow is preferred to ensure full pipe.

Installation: Pipe fi ttings

Omega offers a wide selection of installation fi ttings that control the position of the paddlewheel in relation to the dimensions of the pipe.

3.3 Plastic sensor installation tips

• Inspect the sensor O-rings for nicks and other damage that

may compromise the seal.

• Lubricate the sensor O-rings with a suitable lubricant before

each installation. Do not use any petroleum based lubricant,
which can attack the O-rings.

• Using an alternating/twisting motion, lower the sensor into

the fi tting, making sure the conduit ports on the yellow
housing are pointing in the
direction of fl ow.

• Engage one thread of the

sensor cap then turn the sensor
until the alignment tab is seated
in the fi tting notch.

• Hand tighten the sensor cap.

DO NOT USE ANY TOOLS ON

THE SENSOR CAP.

Wiring

Electrical connections to this product should be made only by
qualifi ed personnel.

To access the wiring terminals:

• Turn yellow cap ¼ turn counterclockwise to remove.

• Remove the two retaining screws and remove the black

cover.

• Route all cables through the conduit ports before

connecting them to the terminals.

• Wiring terminals are rated for 16-22 AWG conductors.

• The cable must be 7 to 10 mm in diameter (0.275 to 0.394

in.) to seal properly in the liquid tight connector.

• The conduit ports have ½ inch NPT threads. After

routing the cables, seal the port with a liquid tight conduit
connector (CDCN-91-LTK) or with conduit.

• For conduit installations:

• Thread conduit with ½ in. NPT threads directly into the
conduit port.

• For conduit with ISO threads, use the black thread
adapter included with the connector kit.

• To comply with NEC requirements, do not use any metal
conduit in the installation.
