1 INTRODUCTION
1.1 General
The ADVANCE®remote meter panels are expertly engineered and carefully tested to assure years of
satisfactory operation. The meter panels are constructed of the finest materials available for gas service.
Proper installation and care will ensure the best operation. Read instructions carefully and retain for future
reference.
These instructions cover Series 200 Remote Meter panels only. Refer to the following for other components:
Remote Meter Panel Dimensions - 100.3004
Vacuum regulator -100.6010
Ejector - 122.6005
Automatic Switchover -100.6030
1.2 Warranty and Service
See 005.9001 for ADVANCE equipment warranty.
NOTE: The Series 200 Remote Meter Panel is designed for use with a Series 200 gas feeder. The ADVANCE
equipment warranty and service policy is null and void, as it pertains to user protection, if the Series 200
Remote Meter Panel is misapplied.
It is recommended that the Gas Dispensing System be inspected and serviced a minimum of once per
year.
More frequent service periods may be required due to: 1) the type, quality and quantity of the gas being
handled, 2) the complexity of the gas supply system, 3) the quality and quantity of water or process liquid
being used to operate the ejector(s), and 4) operation procedures.
More frequent service periods are especially indicated when venting of the VR is occurring during the one
year operational period. This is usually indicative of foreign debris holding the inlet valve open or destruction
of the inlet valve parts caused by the gas quality not up to industry purity standards.

with a common inlet block and individual gas flowmeter outlets. The multiple meter panels are used for the
same gas only.

2 OPERATION
2.1 General
The remote meter panel is designed to complement the Capital Controls’ Series 200 vacuum regulators.
When multiple chlorine gas feed points from the same vacuum regulator are required, a remote meter
panel is utilized. Each remote meter panel is manually set, via the rate valve, to meter the proper amount of
chlorine gas to the feed point. The combined gas feed rate from the remote meters must not exceed the total
feed rate capacity of the vacuum regulator.
NOTE: When remote meter panels are desired to be used for gas flow indication only , the rate valve at the
vacuum regulator is used to adjust gas flow. Therefore, if the vacuum regulator has a rate valve, the remote
meter's rate valve should be removed and replaced with a plug.
2.2 Installation - See Figures 1, 2, and 3
The remote meter panel must be installed in an upright and level position in order to function properly.
The remote meter panel is installed in the vacuum line between the ejector and the vacuum regulator. Locate
the meter panel on a vertical surface convenient for observation and operation, usually in the operator’s area,
with the point of chlorine injection at the desired remote location. Mount the meter panel using two (2) 1/4"
mounting screws for a 3" meter panel, or four (4) 3/8" mounting screws for a 6" meter panel. If the surface is
not suitable for wood screws, choose an appropriate anchor bolt to that surface.
Black polyethylene tubing is normally used for the vacuum line. Do not kink this tubing. It may be desirable
to use tubing connectors, tees or 90° elbows to provide as direct run as possible and minimize kinking
conditions. Use enough tubing length to allow movement of the vacuum regulator for servicing or cylinder
change. Connect the tubing as follows:
2.2.1 Remove the bottom vacuum inlet connector nut from the remote meter panel and slip the connector
nut onto the vacuum tubing coming from the vacuum regulator.
2.2.2 Push the tubing onto the tubing connector and tighten the connector nut HAND TIGHT.
2.2.3 Remove the connector nut from the vacuum outlet (top) of the remote meter and slip onto vacuum
tubing going to the ejector.
2.2.4 Push the tubing onto the tubing connector and tighten the connector nut HAND TIGHT.
NOTE: There may be installations where multiple meter panels may be used from one vacuum
regulator. If this occurs, additional tees may be required to complete the installation.
2.2.5 Some meter panels may be provided as a complete block with a common vacuum manifold, Each
meter would have an individual outlet.
General Design Note: Routing vacuum tubing through unventilated conduit is discouraged. A minute
portion of gas flowing through tubing under vacuum conditions, will slowly diffuse at a molecular
level through its walls and collect in the closed conduit over an extended period of time.

3 START-UP
Follow the instructions provided in the vacuum regulator instruction manual 100.6010 for complete system
start-up procedures.
After the system has been tested for leaks and is operating, adjust the rate valve to the desired gas flow rate.
The flow rates are in PPD (pounds per day) of chlorine.
If feeding sulfur dioxide, the actual flow rate is 0.95 of the scale value. For example, a reading of 50 PPD
(1 kg/h) is actually 45 PPD (0.95 kg/h) sulfur dioxide.
If feeding ammonia, the actual flow rate is 0.50 of the scale value. For example, a reading of 50 PPD (1 kg/h)
is actually 25 PPD (0.5 kg/h) ammonia.
Read the flowmeter scale at the center of the ball.
NOTE: NEVER use the rate valve on the remote meter panel to shut off the gas supply. This valve is for
adjusting flow rate while the system is in operation. If used for shutoff, this valve will be damaged. To shut off
the gas, close the gas container valve.

4 SERVICE
Preventative maintenance kits for each of the assemblies are available from the factory. Each kit contains all
the parts and detailed instructions that are required for complete maintenance. All o-rings and gaskets that
have been disturbed during the disassembly must be replaced during reassembly in order to insure safe,
trouble free operation. Failure to replace these parts could result in a shortened operation period and bodily
injury.
Refer to Figures 4, 5, and 6
4.1 Cleaning the Flowmeter Assembly
4.1.1 Use a coin or washer as a screwdriver and loosen the bottom meter inlet plug while holding the
flowmeter assembly to make sure it does not drop out. It may be necessary to use pliers if the plug
has not been removed for some time.
4.1.2 Loosen the plug about three (3) turns and remove the meter assembly. (Push up and out on the
flowmeter to remove).
4.1.3 Bend a paper clip or wire and pull out the ball stops on each end of the glass tube. DO NOT LOSE
THE METERING BALL.
4.1.4 Clean the inside of the glass tube with a pipe cleaner or bottle brush using wood alcohol, and rinse
thoroughly with warm water.
4.1.5 Clean the metering ball using wood alcohol, and rinse thoroughly with warm water.
4.1.6 Thoroughly dry the glass metering tube. Reassemble the metering stops and ball.
4.1.7 Reinstall the meter assembly by tightening the meter inlet plug making sure that it is on center with
the top and bottom gasket.
NOTE: The meter gaskets can usually be reused. Turn the gaskets over for best results.
4.2 Rate Valve Cleaning
4.2.1 Unscrew the rate valve plug from the valve bonnet.
4.2.2 Remove the valve bonnet from the top of the front body.
4.2.3 Clean the parts by immersing in alcohol or soapy water, rinse, and dry thoroughly with a clean cloth.
4.2.4 The o-rings on the valve bonnet may need replacing if scratched or bruised.
4.2.5 Examine the valve sleeve for nicks or any marks. The sleeve may be removed for this purpose. Use
caution to avoid marking the surfaces.
4.2.6 The o-ring on the outside of the valve sleeve usually may not require replacing.
4.2.7 Inspect the rate valve hole in the meter housing and clean with a damp cloth if necessary. DO NOT
use any sharp tools that may scratch the internal surface. Never use any solvent for cleaning the
plastic, as it will deteriorate rapidly. Wood alcohol can, however, be used successfully.
4.2.8 Apply a thin film of fluorolube grease to o-rings and slide the valve sleeve into the top body.
4.2.9 Replace rate valve.
