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.

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.

Location of Fitting

Recommended sensor upstream/downstream mounting

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

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.

AVERAGING and SENSITIVITY

Averaging and Sensitivity Settings

• Because ideal fl ow conditions are often impossible to achieve, the fl ow rate is often erratic, which causes any control features (ie;
relays, 4-20 mA loops, etc.) that are associated with the fl ow rate to be erratic.

• The best solution to these problems is to correct any piping defi ciency that causes the instability. This may involve longer straight
runs upstream, reducing the pipe size to maintain a full pipe at all times, and other installation changes. But in many situations
these measures are simply not possible.

• The FPB meter provides two tools that are designed to "work around" these defi ciencies. The Averaging and the Sensitivity
features should be studied before making adjustments.

Averaging Time in Seconds (Factory set: 0 seconds)

• Set the time the meter will use as the averaging period. The range is from 0 (no average applied to input) to 100 (seconds of
averaging applied to input).

Use higher averaging times to smooth the display and current output where the fl ow in the pipe is erratic.

Quick Response Sensitivity (Factory set: 0)

• Set the relative degree of change in the fl ow rate required to allow the FPB to disable the AVERAGING and jump to a new fl ow rate
immediately. The scale is from 0 (Least sensitive, averaging is never disabled.) to 9 (a very small change in fl ow rate will disable
the averaging).

With AVERAGING set to 0 (zero) and with SENSITIVITY set to zero,
the FPB responds to every unstable shift in the fl ow. The dashed red
line represents the actual output of the fl ow sensor in unstable fl ow
conditions.

With AVERAGING set to 50 seconds and SENSITIVITY still set to
zero the fl ow rate is stabilized, but a sharp change in fl ow rate is not
represented for 50 seconds or longer. (dotted green line).

With AVERAGING at 50 seconds and SENSITIVITY set to 4 OR 5,
the fl ow rate is stabilized, while the sudden shift in fl ow is refl ected
very quickly. (Solid blue line)

NOTE: The SENSITIVITY function is ineffective if the AVERAGING function is set to zero (seconds).

DIVIDER allows you to set a scaling value (P-Factor) from

Example: If the P-Factor is set for 2, then the FPB will output
one pulse for every 2 pulses received from the sensor.
This selection enables the output frequency to be scaled down
to match associated equipment capabilities.

PULSE TOTAL Output = Input pulses ÷ (K-Factor • P-Factor)

TOTAL is a traditional pump pulser function. This selection will
allow the entry of a K-Factor to defi ne a volumetric unit, then set
a P-Factor to defi ne the number of volumetric units required to
generate one pulse out.

Example:
Set the Total Pulse output so there is one pulse out for each 2
gallons that passes the sensor if the K-factor is 3.0.

1. (K) Factor = 3.0 (pulses in per gallon)

2. P- Factor = 2 (gallons out per pulse)

In PULSE DIVIDER mode the P-Factor divides:

The pulse stream from the paddlewheel sensor will be divided
by the P-Factor. The resulting frequency is output through a
relay.

In PULSE TOTAL mode the P-Factor multiplies:

The pulse stream from the paddlewheel sensor is divided
by the K-Factor MULTIPLIED by the P-factor. The resulting
frequency is output through a relay.

The Flow Switch has one relay (SPDT or solid-state) that can be programmed as a HIGH (Hi)
alarm or a LOW (Lo) alarm.

1. Select HI or LO Relay Alarm logic

A HI alarm will be activated when the
fl ow rate rises ABOVE the setpoint.

A LO alarm will be activated when the
fl ow rate falls BELOW the setpoint.

The factory setting is Hi(gh).

2. Program the SETPOINT.

The SETPOINT is the fl ow rate
where the relay will be energized.
The factory setting is 5.0000.

Maintenance and Cleaning

The Omega FPB Series requires very little maintenance.

• If the paddlewheel becomes fouled, it can be cleaned with mild detergents and a small brush.

• The electronics portion of the FPB does not require maintenance or cleaning.

Rotor Replacement Procedure

1. To remove the rotor, insert a small screwdriver between the rotor and the ear of the sensor.

2. Twist the screwdriver blade to fl ex the ear outward enough to remove one end of the rotor and pin.
DO NOT fl ex the ear any more than necessary! If it breaks, the sensor cannot be repaired.

3. Install the new rotor by inserting one tip of the pin into the hole, then fl ex the opposite ear back

enough to slip rotor into place.
