ACCESSORIES FOR THE MODEL 9623-07
LEAKAGE RATE MONITOR
Quick Fill Manifold
Part Number: 9623QFM
This manifold allows for the quick filling of large volumes. This stainless steel manifold incorporates 1” pipe, welded fittings and ¼ turn ball valves
This device allows for quick pressurization, testing as well as quick depressurization as shown below.
Quick Fill Configuration
This configuration allows for the test
volume to be directly filled from the
air supply though a 1” line. The pressure
gauge on the 9623 may be used to monitor
the test volume pressure as it is being filled
Testing Configuration
By closing the inlet and outlet valves and
opening the vent valve, the manifold both
allows the test volume to be tested by the
9623 and ensures that any possible supply
air leakage through the manifold cannot
bypass the monitor and enter the test
volume unmetered
Quick Venting Configuration
This configuration allows for the test volume
to be quickly vented to though the 1” line.
The pressure gauge on the 9623 may be
used to monitor the test volume pressure
as it is being vented. The test volume air
may be either discharged to ambient or
routed to a remote location.
Check Nozzles
Part Number: 9623CN-XXXX-YY.Y-ZZZZ
Calibrated orifices, certified to flow at a prescribed flow rate at a specified inlet pressure.
Just screw a check nozzle into the test port of the 9623-07 and set the monitor pressure to the test pressure labeled on the Nozzle Check.
The 9623-07’s Nozzle Check Screen will tell you if the measured flow rate is within tolerance to the expected flow rate labeled on the Check Nozzle.
This allows the users to field check the accuracy of each flow meter prior to use. This eliminates questions concerning the validity of any test results should an monitor become lost, contaminated or be later found out of tolerance.
All nozzles are 1/4” or 3/8 “ NPT and made from stainless steel.
Each Check Nozzle comes with a NIST traceable certificate of calibration.
A ¼” NPT Check Nozzle certified to flow 26.5 scfh with a 56.0 psia inlet pressure would be have the part number listed below.
9623CN-26.5scfh-56.0psia-1/4”NPT.
Pressure Decay Module
Part Number: 9623PDM
The quickest and most accurate way to leakage rate test a large volume, (such as airlocks) is using the pressure decay method. The 9623-07 is now capable of also performing pressure decays tests.
This module measure pressure and temperature and connects to the 9623-07.
A five conductor electrical connection between the 9623PDM and the 9623-07 is required. This maybe accomplished using an existing electrical penetration.
Alternately, for airlock testing, Graftel can supply a paper thin flat cables that the airlock door can be closed on. These cables conduct the required signals while at the same time allowing a perfect door seal
The 9623-07’s pressure decay screen reads pressure and temperature data from the Pressure Decay Module, (PDM)and displays the leakage rate, air pressure and temperature. This capability is included in all new 9623-07s with the simple connection of the 9623PDM. Older units will also require a firmware update, (available from Graftel at no Additional cost).
9623PDM Specifications
Pressure: 0 to 100 psia, 0.05% of Full Scale Accuracy
Temperature: 32 to 130 F, 0.5 F Accuracy, RS-232 Output
NIST Traceable Calibration Certificates on both Pressure and Temperature
Supply Air Conditioner/Pre-Regulator
Part Number: MC-1399K12
Most flow meters are found out of tolerances are due to the use of dirty, wet or oily supply air. This simple low cost device connected to the 9623-07 inlet alleviates all of those conditions. This device both filters particles and traps any entrained oil or water from the supply air before it can enter the 9623-07.
In addition, because this device also includes a pressure regulator and inlet pressure gauge, the supply air pressure to the regulator may be both monitored and automatically controlled. This adds insurance that leakage rate test results are immune to any sudden changes in supply system air pressure.
A transparent polyurethane bowl won't crack in systems heavy with synthetic compressor oils and allows you to see what's being filtered. The drain is manual. The filter has a polypropylene element and removes particles as small as 5 microns. The regulator’s accuracy is ±1%.
Max inlet pressure is 150 psig and the regulating range 0 to 125 psig. This regulator can flow up to 1000 scfh, (approx 500 slm) at 100 psig.
Extended Use Battery Packs
The 9623-07 is supplied with a 9.5 amp-hr NMH battery pack and charger. This unit will power the 9623-07 for approximately 9 hours. When longer battery life is needed, any of the three lead-acid battery pack/chargers shown below may be ordered.
