1.0 Introduction.

1.1 This manual covers the following Omega instruments.

1.1.1 Omega FLR2000 series Flow Meters.

1.1.2 Omega FLV2000 series Flow Controllers.

NOTE: It is important that you read this manual before
installing or operating any of the instruments. Some sections
apply to all of the listed instruments and will be marked
accordingly. There are sections which apply only to the series
you have purchased and these are also marked accordingly.

1.2 Unpacking Your Instrument.

1.2.1 Inspect Carton for Visible Damage.

Your instrument was packed to withstand normal
shipping. If there is any visible damage to the carton,
you should contact the shipping company immediately.

1.2.2 Unpack Your Instrument.

Open the container carefully and inspect for concealed
shipping damage. If there is damage, this should be

2.0 Installation.

2.1 Primary Fluid Connections.

Omega FLR2000 series Flow Meters and Omega FLV2000
series Flow Controllers are manufactured with a 1/2” NPT
internal thread on both the inlet and outlet ports. Omega kit
model FLR2000-MC is available for installation of these
instruments utilizing standard O.D. tubing sizes of 1/4”, 3/8”
and 1/2”. The kit material is black polypropylene.

Inspect all parts of the system including pipe, tubing and
fittings for dust or other contaminants before assembly. Omega
FLR2000 series Flow Meters and Omega FLV2000 series Flow
Controllers are tested with water and then closed with a plastic
plug before shipping. Upon removal of the plugs, water may
drip from the flow body. You should remove the plugs only in
a location which will not be damaged by a small amount of
water, and the location should also be free of dust or other
contaminants which could enter the chamber.

If Teflon tape is used as a thread sealant for the NPT
connections, you must not allow pieces of the tape to fall into
the flow body as this could clog the orifice. Liquid or paste
thread sealants are not recommended. Thread sealants are not
to be used on the tube fittings. When removing fittings which

proper packaging to prevent breakage in transit. In the
event that instruments returned for repair are found to be
free from warranted defects, then Omega may, at its
discretion, charge a fee to the customer for service. The
customer shall be notified before repairs are made as to
the warranty status of the needed repair. All shipping

charges shall be paid by the customer.

All instruments returned for servicing must have a signed
certification attached which states that returned
instruments have been purged and neutralized of any
hazardous materials including but not limited to
corrosive, radioactive, toxic or infectious. This
certification form is available from Omega customer
service.

have been sealed with Teflon tape, you must clean both the
internal and external threads to prevent pieces of tape from
falling into the flow body.

2.2 Omega Accessory FLR2000-MC Fitting Installation.

If the fittings supplied in Omega Accessory FLR2000-MC are
used, the tubing should be inserted as follows.

2.2.1 Loosen the nut sufficiently so that the O-ring is not

compressed.

2.2.2 Using tubing of the O.D. size for which the fitting is

designed, cut the tubing with a square end and inspect to
see that there are no sharp edges that could damage the
O-ring in the fitting.

2.2.3 Insert the tubing carefully, moving the tub ing in a slow

circular motion until it passes through the stainless steel
grab ring, the washer and the O-ring, and “bottoms” in
the fitting. You should not have to use excessive force to
insert the tubing. If the tubing does not go in easily then
you should unscrew the nut completely and visually
inspect to verify that the O-ring has not been pushed into
the fitting well. You can push the tube through the O­ring and into the fitting with the nut out of the way,
however you should be careful to not push the grab ring
farther up the tube than it will be when the nut is

tightened as the grab ring cannot be moved in a
tightening direction on the tube without damaging the
grab ring and/or the tube.

2.2.4 Once the tubing has “bottomed” in the fitting, you should

hand tighten the nut, forcing the grab ring to gr ip the
tubing surface and compressing the O-r ing. The nut
should come close to the body of the fitt ing but does not
have to contact the body.

2.3 Checking For Leaks.

7

The entire system should be checked for leaks using a fluid
which is not hazardous and using a system pressure that is
within the stated limits of the instruments. *See Maximum
Operating Pressure in section 5.12.

2.4 Mounting.

2.4.1 Locating the Meter.

Omega FLR2000 series Flow Meters and Omega
FLV2000 series Flow Controllers are not attitude
sensitive; however, it is recommended that they be
installed with the flow body in a horizontal position. The
display and m embrane switches are designed for use in
the horizontal.

WHEN FACING THE METER.

2.4.2 Opening the Box.

It is necessary to open the box in order to access the

mounting holes in the back panel of the box. In order to
remove the front cover, first remove the
power/communication I/O 18 pin plug (this plug can be
removed by rotating the locking ring counterclockwise to
a stop and then gently pulling down on the plug). The
front cover with all the electronic components and
circuitry can then be removed by loosening the four
plastic screws on the front corners of the enclosure (they

have a retainer feature and can be left in the front cover
after loosening about 1/2"), separating the cover from the
back of the box about 4” (enough to turn the front cover
90° to the side) and then disconnecting the sensor cable
connector (the middle connector on the bottom left side
of the circuit board which is attached to a cable running
through the bottom back of the box). The connector
which is removed has a center latch release which must
be depressed before pulling the connector from the
mating end. You can then put the front of the box with

the electronics to one side while mounting the back of the
box to the mounting surface. Please use caution while the
box is open to insure that no liquids or dirt are allowed to

8

contact the interior components of the box as this may
cause premature meter failure.

2.4.3 Attaching the Box.
The box may be attached by inserting a fastener in either

the four holes in the corners of the box (if this is used,
then you must be careful to not damage the threads

toward the upper end of the holes which are used to
attach the front of the box to the back of the box), or you
may use the four holes in the back of the box (if these are
used, there are four plastic covers to place over the screw
heads). The box must be attached securely with the
proper size and style of fasteners for the surface on which
it is to be mounted.

2.4.4 Reinstalling the Front of the Box.
Once the back of the box has been mounted and the

plumbing has been attached, the front of the box can then
be reattached in the reverse manner. To insert the 18 pin
connector (or 7 pin connector), it will be n ecessary to
pull the lock ring toward the body of the plug to the open
position and rotate the locking r ing so that the rib on the
lock ring lines up with the rib on the inside of the plug
body. Then align the locator rib on the plug with the
mating slot on the socket and insert the plug. When the
plug is fully inserted then push the locking ring toward
the panel socket and rotate clockwise until it stops.

3.0 Electrical and I/O

3.1 Power Supply

The standard power supply furnished with all Omega FLR2000

series Flow Meters and Omega FLV2000 series Flow
Controllers consists of an ungrounded wall adapter which plugs
into a 120VAC, 60 Hz standard receptacle and delivers 15 VDC
with maximum 500 mA current to the instrument through pins
1 & 2 of an 18 pin circular watertight industrial I/O connector
which plugs into a mating 18 pin socket on the bottom right

side of the front portion of the enclosure. If it is necessary to
remove the front cover for service, first remove the
power/communication I/O 18 pin plug (this plug can be
removed by rotating the locking ring counterclockwise and then
gently pu lling down on the plug). The front cover with all the
