Leak Rate Monitor

Water Leak Rate Testing Machine

Water Leak Rate Testing Machine

An easy-to-operate system designed to be used, this monitor allows for the precision testing of water tested containment isolation valves using plant demin or service water

Replace with The Model 9623-H2O, hydro leak rate testing machine.
Description:
9623-H2O Hydro Leak rate Monitor.
The Model 9623-H2O is an easy to operate system designed to be used This monitor allows for the precision testing of water tested containment isolation valves using plant demin or service water. This unit comes with 2 or three flow ranges, depending on your site-specific needs and two pressure channels, one to monitor inlet pressure and one for your test pressure.
The 9623-H2O quantifies the component under test’s leakage rate by maintaining a constant water pressure against the barrier being tested while measuring the water flow rate needed in order to maintain that pressure constant. A steady supply at a constant pressure of clean water is required to operate.
Flow Meter
Using two or three ranges, a 1000 to 1 turn-down ratio is achieved with a 1% of full-scale accuracy over each of the ranges. Each flow range is customer selectable to fit your site-specific needs.

Model 9623-EV Leak Rate Monitor

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.

On-Site Leak Rate Monitor Calibration and Repair

On-Site Leak Rate Monitor Calibration and Repair

Leak Rate Monitor and Gas Flow Meter Calibration and Repair at Your Facility

Graftel can calibrate and repair Local Leakage Rate Monitors on your site. This includes contaminated LRMs inside of the RCA. Our team of experience technicians have all been recently badged US nuclear power plants and are experience in working inside of the RCA.
For those critical gas flow meters that just can’t leave your site, Graftel, LLC. now offers calibration services at your facility.
Gas Flow Measurement, up to 1500 slm, (3000 scfh)
Graftel uses a set of PC controlled portable laminar flow elements to achieve laboratory gas flow measurement and calibration accuracies of up to 0.5% of reading at your facility. The following gas flows may be measured; air, nitrogen, hydrogen, helium, propane, argon, methane, ethylene, carbon dioxide, oxygen and acetylene. Other gases or custom mixtures maybe used upon request.
Graftel, LLC. can calibrate almost all types of LRMs and flow meters with accuracies of up to 0.5% of reading.

Leak Rate Monitor Accessories

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:
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.
