Model 5 Prover Software Manual
6. Equipment Setup
Important:
Before setting up your Model 5 ROOTS Prover, it is important to review this manual for all operat-
ing and safety instructions. Read all instructions within a specific step before executing any of the actions
associated with that step.
This procedure assumes that the Model 5 Prover (and associated hardware) has been unpacked from its
shipping container and is ready to be properly configured for testing.
You do not have to keep the Prover Cart perfectly level when testing, but keep it as level as possible. Avoid
severe tilting of the system during operation.
Isolate the Field Meter to be tested from any gas before testing. Follow all recommended and/or company
safety procedures.
For safety reasons, always use positive pressure to purge the Field Meter (meter to be tested) prior to
initiating a test using the vacuum test method. Failure to purge a Field Meter can result in severe
personal injury and/or equipment damage. See section 10.5 for the Meter Purging Procedure.
6.1 Field Meter Setups
1.
Position the Field Meter for testing. Make sure that there are no loose objects or litter in front of
the air intake; it functions as a vacuum during testing, and foreign material may be drawn into
the Prover.
2.1 Setup for the 10M or 2M/10M
Connect the 25 ft. flexible Prover Hose to the outlet of the Field Meter and connect the other
end of the hose to the inlet quick-disconnect nipple of the appropriate Master Meter. Where
possible, put a loop in the hose between attachments to lessen pulsations between the Master
Meter and the Field Meter.
Ensure that if the Prover has two Master Meters, the Hose Cap is firmly attached to the inlet
quick-disconnect nipple of the unused Master Meter. For Model 5 Provers with only a single 10M
Master Meter, install the Expander Hole Plug in the open end of the vertical section of the 2 in.
pipe (blower manifold) located between the Blowers and the 10M Master Meter.
2.2 Setup for the 5M (Mobile 5)
Connect the 12 ft. flexible Prover Hose to the outlet of the Field Meter and connect the other
end of the hose to the inlet quick-disconnect nipple of the Master Meter. Where possible, put a
loop in the hose between attachments to lessen pulsations between the Master Meter and the
Field Meter.
2.3 Setup for the 20M or 5M/20M
Connect the 25 ft. flexible Prover Hose to the outlet of the Field Meter and connect the other
end of the hose to the inlet quick-disconnect nipple of the appropriate Master Meter. Ensure
that if the Prover has two Master Meters, the Hose Cap is firmly attached to the inlet quick-
disconnect nipple of the unused Master Meter.
2.4 Setup for the 10M/80M
Connect the 8 or 25 ft. Flexible Prover Hose to the outlet on the Field Meter and connect the
other end of the hose to the inlet of the appropriate Master Meter (the 8 ft. Flexible Prover Hose
should be connected to the Acoustic Filter). When using the 10M only, make sure that the Hose
Cap is attached to the inlet quick-disconnect nipple of the unused Master Meter or the quick-dis
connect nipple on the piping. When using the 80M only, make sure that the 25 ft. Flexible Prover
Hose is connected to the quick-disconnect nipple of the Master Meter being used or the quick
disconnect nipple on the piping.
