Model 9623-EV Leak Rate Monitor

The Model 9623-EV is a new revision to it improves upon a proven design

The Model 9623-EV is a revision built from an industry proven design. This unit can function with no power source by utilizing an internal internal air/electric generator.

It has three flow ranges and one pressure channel. The 9623-EV quantifies the component’s leakage rate by maintaining a constant gas pressure against the barrier being tested while measuring the gas flow rate needed in order to maintain that pressure constant. Using three ranges, a 1000 to 1 turn-down ratio is achieved with a 1% of full scale accuracy over each of the three ranges. Each flow range is customer selectable. Full scale flow ranges up to 400 slpm may be ordered. This same unit may also be used to perform temperature compensated pressure decay tests on large volumes.

Leak Rate Monitor Accessories

Graftel offers a full line of accessories to fit your complete LRM needs

RCXD17 Mobile Utility Cart

The ultimate LRM accessory. The RCXD17 is a robust, versatile and portable workstation. The RCXD-17 is designed to securely store and operate LRMs. Any of Graftel’s standard sized leakage rate monitors (LRMs) will fit the workstation. This units also incorporates all available accessories and then some in one package. A mini unit is also available upon request.

This includes:

Industrial power 4 port outlet (NEMA 5-15)
Lockable caster wheels
Lockable LRM storage & lockable tool storage drawers.
Internal LED lighting
Quick fill manifolds
Pre filter
Water trap
High capacity rechargeable battery pack (20 hrs. additional run time)

Quick Fill Manifolds

Available Sizes:

This manifold allows for the quick filling of large volumes. This stainless steel manifold incorporates 1” and 1/2″ pipe, welded fittings and ¼ turn ball valves. This device allows for quick pressurization, testing as well as quick depressurization as shown below.

Check Nozzles

Available Sizes:

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. 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.

NPT Check Nozzle certified to flow 26.5 scfh with a 55.0 psia inlet pressure

Pressure Decay Option

Part Numbers:9202 (Temp Sensor) & E-20 (High Accuracy Pressure Transmitter)

The quickest and most accurate way to leakage rate test a large volume, (such as airlocks) is using the pressure decay method. Graftel’s temperature sensor sensor Model 9202 can be used with high accuracy pressure transmitter to performing pressure decay tests on LRMs.

The LRM pressure decay screen reads pressure and temperature data from the 9202 and displays the leakage rate, air pressure and temperature.

Supply Air Conditioner/Pre-Regulator

Part Number: GT-1399K12

Most flow meter as found out of tolerances are due to the use of dirty, wet or oily supply air. This simple low cost device connected to the LRM 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 LRM

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.

Graftel & Alicat Flow Meter Calibrations Made Easy

Alicat and Graftel are partnering to ensure quick turnarounds on recalibrations

Graftel has been a customer of ours for almost two decades and has developed into a highly valuable partner. As a full service accredited lab for gas, liquid flow, pressure, temperature, air velocity, and humidity, they can support a variety of calibration needs in the market. Our team has fully trained Graftel to calibrate Alicat gas flow meters and controllers, and we recommend using their facilities for quick turnarounds on recalibrations (10 days, with 1 day expedite option).

Graftel has calibrated thousands of Alicat meters and controllers over the years for a variety of end users in industries across the world. With this level of experience, naturally it would be a great fit to begin a partnership with Alicat as one of their certified OEM calibration lab vendors. Maintaining industry leading turnaround time and high level quality services, Graftel and Alicat can always ensure customer needs and expectations are surpassed.

Dave Glover, President of Graftel

Calibrating your flow device at Alicat or Graftel

Most Alicat devices are recalibrated by our service team in-house. When a device is sent to Alicat, our team first double checks and logs analog signals, settings, sensor health, LCD functionality, and connector threading. They then calibrate the device using NIST-traceable standards. We recommend sending your device back to Alicat for a full inspection and calibration at least once within the first three years to ensure full functionality.

Graftel performs calibrations for Alicat flow meters and controllers. They are, however, not trained to perform full inspections or repairs. If you are uncertain whether you should calibrate your device at Alicat or Graftel, reach out to our application engineers, and they will help you find the right solution.

Why recalibrate?

Over time, particulate deposits or minor physical changes within the flow body or internal electronics can lead to deviations from the calibrated flow curve. Recalibration brings instruments back to their optimal calibration specifications.
