Introduction
This manual contains instructions to install the Balance model of a Veeder-Root Vapor Flow Meter (VFM) in the
dispenser vapor return line.
The Vapor Flow Meter described herein is referred to in the 450+ GUI setup/report/
diagnostic screens as an Air Flow Meter (AFM).
For a VFM that will be direct wired to a TLS console, this manual assumes all preliminary site preparation is
completed, and that wiring from the console to an intrinsically-safe junction box is in place for the VFM and meets
the requirements set out in the appropriate console Site Prep manual.
For wireless VFM installations, follow the steps herein to install the VFM itself, but refer to manual 577013-964 for
installation of, and connection to, the wireless components.
Contractor Certification Requirements
Veeder-Root requires the following minimum training certifications for contractors who will install and set up the
equipment discussed in this manual:
All service personnel on site must comply with all recommended safety practices identified by OSHA and your employer.

Introduction Before You Begin
5
Before You Begin
• Comply with all recommended safety practices identified by OSHA (Occupational Safety and Health
Administration) and your employer.
• Follow all installation requirements as per NFPA (National Fire Protection Association) 30, 30A, and 70.
• Review and comply with all the safety warnings in the installation manuals and any other national, State or Local
requirements.
• When direct wiring to a TLS console, a 2-conductor, 18 AWG shielded cable must be installed in intrinsically
safe conduit from each dispenser to the intrinsically safe wiring compartment of the TLS console. The cable
length between the console and sensor must not exceed the distance stated in the appropriate Site Prep
manual. Conduit for direct wired installations must be properly sealed in accordance with the latest National
Electric Code (NFPA 70) and the Code for Motor Fuel Dispensing Facilities and Repair Garages (NFPA 30A)
since they pass from a Class I, Division 1 or 2 hazardous area into a non-hazardous area.
• Conductors of different intrinsically safe circuits run in the same cable/conduit must have at least 0.01 inch
(0.25 mm) of insulation.
• Debris from plumbing modifications should be flushed through the piping system prior to installing the ISD
Vapor Flow Meter.
• Use only UL recognized Gas/TFE yellow plumbing tape on all fittings. Do not use pipe dope to seal pipe
threads or fittings in and out of the Vapor Flow Meter.
• Intrinsically safe devices must be installed in accordance with Article 504 of the National Electrical Code, ANSI/
NFPA 70, for installation in the United States, or Section 18 of the Canadian Electrical Code for installations in
Canada.
Veeder-Root Parts
• The Balance VFM installation kit is shown in Table 1.
Tools Required
• Pipe wrench suitable for tightening 1-inch NPT pipe.
• 1/2’’ socket wrench to install Vapor Flow Meter flange bolts.
• Necessary pipe fitter’s equipment and a non-hazardous work space suitable to modify dispenser vapor line for
Vapor Flow Meter installation, when necessary.

Installation
Before installing this device, turn off, tag/lock out power to the system, including console and submersible pumps.
Remove the dispenser’s lower sheet metal doors to access the vapor plumbing.
Prior to modifying any piping in the dispenser, consult the dispenser manufacturer to
determine if ISD ready retrofit kits are available. Any factory installed plumbing that must be
modified in order to install the VFM, must be removed to a non hazardous work area before
any cutting or threading takes place. After modifications to any plumbing, it must be
reinstalled in accordance with the dispenser manufacturers installation guidelines.
Above Shear Valve Installs
1. Loosen any factory installed mounts and/or brackets in order to provide room to disconnect any factory
installed vapor return plumbing from the shear valve.
2. Disconnect the factory installed vapor return plumbing from the vapor shear valve (see Figure 1).
3. Remove any unneeded field installed plumbing above the vapor shear valve. The Vapor Flow Meter with
flanges attached can be used for sizing the required head space of approximately 8 inches. Approximately 3
inches of clearance is required on both sides of the piping to accommodate the width of the meter body.
4. Thread one of the flanges (two provided in installation kit) onto the dispenser vapor return piping.
5. Install any necessary plumbing and the lower flange above the vapor shear valve. The use of 90° elbows
should be kept to a minimum to minimize pressure drop, maximize vapor collection efficiency and to prevent
liquid traps. All horizontal plumbing must pitch to drain.
IMPORTANT! Upper and lower flanges must align to within 1/16” center-to-center before
installing flow meter. If piping is improperly aligned, torque could damage the flow meter and
result in vapor leakage.
6. Clean all debris around the inlet and outlet plumbing prior to installing the VFM. DO NOT blow compressed air
through the VFM to prevent damaging the internal screens.
7. Install the o-ring into the lower mounting flange.
8. Taking care that foreign material (chips, debris, sealant, etc.) does not enter the open piping or VFM, carefully
insert the o-ring and then connect the VFM to the upper flange. Note that the flow arrow on the side of the
meter body must point down.
9. Connect the lower flange to the VFM.
10. Tighten any loose fittings and hardware.
11. Install a cord grip from the kit into the I.S. junction box. Route the VFM cable into the I.S. junction box and
tighten the cord grip. Observing polarity, connect the VFM wiring to the field wiring from the TLS console with
wire nuts (see Figure 4). Seal wire nuts in epoxy sealant following the instructions in Figure 5.
For Wireless installations skip Steps 11 - 13. The VFM connects to a TLS RF transmitter, not
to field wiring from the TLS Console (see manual 577013-964 for instructions).
12. Push the epoxy sealed bag into the junction box. Replace and tighten the junction box cover.
13. Connect VFM field wiring in the TLS Console to the USM Module (TLS-450PLUS - Figure 6), or to the Smart
Sensor Module (TLS-3XX - Figure 7), as appropriate.
14. Replace the lower sheet metal doors in the dispenser
15. After all Vapor Flow Meters are installed, pressurize the tank ullage space and vapor piping to at least 2
inches WC and test piping connections for leaks using leak detection solution.

3. Install the Vapor Flow Meter over the lower flange.
4. Connect the upper flange with o-ring above the Vapor Flow Meter.
5. Using a close nipple, thread the shear valve into the upper flange.
6. Using nipples, unions, and other plumbing as required, connect the plumbing outlet to the shear valve.
7. Install a cord grip from the kit into the I.S. junction box. Route the VFM cable into the I.S. junction box and
tighten the cord grip. Observing polarity, connect the VFM wiring to the field wiring from the TLS console with

Instructions:
NOTE: When temperature is below 50°F (10°C), keep
resin in a warm place prior to mixing (e.g., in an
inside pocket next to body).
1. Open epoxy sealant package, and remove resin pak.
2. Holding resin pak as shown in A, bend pak along
long length.
3. As shown in B, firmly squeeze the RED SIDE of the
resin, forcing it through the center seal and into
BLACK SIDE.
4. Mix thoroughly to a uniform color by squeezing
contents back and forth 25-30 times.
5. Squeeze mixed, warm resin into one end of bag and
cutoff other end.
6. Slowly insert wiring connections into sealing pack
until they fit snugly against the opposite end as
shown in C.
7. Twist open end of bag and use tie wrap to close it off
and position the tie wrapped end up until the resin
jells.
CAUTION: Epoxy sealant is irritating to eyes, respiratory system, and skin. Can cause
allergic skin reaction. Contains: epoxy resin and Cycloaliphatic epoxycarboxylate.
Precautions: Wear suitable protective clothing, gloves, eye, and face protection. Use
only in well ventilated areas. Wash thoroughly before eating, drinking, or smoking.
