Flow testers

With more than 55 000 flow testers currently in operation throughout 32 countries, ATEQ remains by far the largest manufacturer of leak testing instruments for production lines in the world. 
With the 5 series, ATEQ introduces the fastest, most reliable, versatile, user friendly flow tester range in the market, and by far the most popular ever built.

Flow testers : FEATURES

Discovering “Pascal”

At the heart of every ATEQ flow tester lays a patented differential pressure transducer, the performance of which remains unmatched in the industry.

This technological marvel can measure pressure variations of 0.1 Pascal (That’s 0.000145 PSI) and handle test pressures up to 80 Bars (1160 PSI !).

170 Bar POC Naturally, all of this comes calibrated by our traceable to international standard calibration lab.

Experience speedy flow testing

Ever found yourself frustrated with an aging and slow flow testing test station?

The 5 series comes fully equipped with the latest technology in dry and clean flow detection

30 of our engineers work all year long to improve the already state of the art technologies that ATEQ has been mastering for the past 30 years.

Easier to use would have been insulting

Programming a flow tester used to be a job in itself, and while ATEQ has always been at the forefront of user friendliness in the past, it still remained a task most were reluctant to do.

Now this is all history with the 5 series ‘s interface.

You’ll find yourself achieving fantastic results in no time. Programming up to 64 sequential programs using different pressures and cycle times has never been easier.

At last … a compact flow tester

The 520 is the smallest flow tester on the market and yet contain the same technology as the larger and more traditional 3U versions.

So what is the advantage of the reduced size?

The smaller the instrument, the closer you can position it to your test rig thus reducing the overhaul test volume.

By reducing the test volume, you decrease the cycle time and increase the accuracy of the test.

Service is everything

No matter how good your flow tester is right out of the box, it is its performance 10 years later that makes it a good or a bad choice.

ATEQ is the only company in its field that can service its instruments with its own engineers in 25 countries.

And as if this wasn’t enough, we’ve extended our service to customers in an additional 12 countries with local certified agents.

As a matter of fact, we have so many representatives of our own around the world, that the sun never sets on ATEQ’s service network.

So if your problem is really urgent, an English speaking technician is always reachable 24 hours per day 5 days a week (See our service page for more details).

ATEQ also delivers extensive training courses for maintenance as well as engineering personnel.

And you can count on our service technicians through the year to calibrate your devices on-site or in our local premises if you prefer.

Finally, we are here to advise you on preventive maintenance to avoid any interruption of your production.

Enclosure

Same technology, Multiple formats

Because a flow tester can be used in so many different environments, we have designed several models that adapt to every need we have encountered in 35 years of experience.Whether your 5 series ATEQ goes into a fully automated production line or in a lab, we have the model that suits you best.

 420/520 : Compact Flow tester
Instruments based on the 420/520 format allow you to position the measuring unit extremely close to your test part, thus reducing the tested volume.
535 : For manual test stations
A large number of our flow testers are used in manual test stations.
The 535 line has been designed specially to adapt to all manual station requirements.
A key protected interface lets engineers set up the device while a front panel with industrial strength buttons and a reject/pass light remain accessible to the operator to run the test.Finally, once again, the measuring head which is located in the base of the instrument lets you position the measuring device close to the test rig, thus reducing the total volume tested.
570 / 580 : Traditional 3U replacement units
If you wish to upgrade your aging 3U flow tester with a 5 series model, the 570 and 580 fits exactly that need.No need to redesign your existing machine to fit the new instrument.
Simply remove the old one and install the 570 or 580 in its place.
The 3U standard is also appreciated in laboratory environments where the 580 and its large LCD display allow you easy access to all test programs and functions.

5 Series interface / Series 3 and alphanumeric…

Enables the instantaneous swapping of a 3 series instrument with a new generation 5 series instrument whilst conserving the same connections as far as the PLC is concerned.
3 interfaces are available:
F5/F3 – F580/F3 – F580/F alphanumeric

Inputs / Outputs module

For the remote management of measurement units (heads) when long lengths of cables separate the measurement units from the central.
Enables the minimisation of the lengths of cable used between the elements.
Management of 3 units max.

Parameter storage / result modules

Two separate modules which enable the transfer of settings from one instrument to another and the recovery of the measurement results for software based assessment.

Y Valve and Mini Y Valve

The Y valves and mini Y valves are 3/2 spring recoil valves with pneumatic or electric control.
They offer a high level of protection against leaks.

CDF: Leak / Flow calibrator

The leak / flow calibrator allows the checking of the calibration of leak and flow measurement instruments, as well as calibrated leaks and jets.
This portable, compact and user friendly instrument is essential for checking the accuracy and repeatability of all leak and flow testers.

2 pneumatic outputs

The optional pneumatic outputs (internal or external) are Two pneumatic pulses that are being activated at anytime during the cycle and under pre-set conditions such as: Start of cycle; end of cycle; Good part; Bad part; …Etc. They allow the user to operate simple jigs without having to rely on a PLC.

Electronic regulators

Thanks to electronic regulators, an instrument can be programmed with a different pressure on each test cycle.
It can also be used as a pre-fill pressure to speed up the cycle time.

Dual pressure

The dual pressure option of ATEQ’s differential pressure decay instruments allows the reduction of cycle time through faster fill time.Used in conjunction with the pre-fill software option, the dual pressure raises the test pressure faster than conventional fill times.It also helps reduce cycle on flexible parts.

Calibrated Leak / Jet

The calibrated leak or jet allows the checking of the calibration of leak or flow measuring instruments. Available in standard and customised versions, they simulate an exact leak or flow rate inside the test circuit to check that the instrument detects the right value.

Quick sealing connectors

The quick sealing connectors pneumatically compress a soft rubber cylinder around an internal or external diameter.
Together with the optional pneumatic outputs of ATEQ’ instruments, these devices offer a perfect solution to build fixtures quickly and inexpensively.

Filtration kit

ATEQ instrument require a clean and dry operation to remain reliable.
The Ethafilter ensures that the ATEQ operates under the ISO 8573-1 standard.

Winateq

Winateq is an integrated software which is compatible with our custom windows based applications.
It is easy to install and includes a system configuration back up.
It can also be used as a base to develop customised applications. (Import and export function to spread sheet application).

Thermal printer

Connected to the RS 232 port of ATEQ’s instruments, this thermal printer can print results in ASCII format, including the details of cycle times and results.

Very handy in laboratory operation to automatically print dozens or hundreds of results.

Flow testers : FACTSHEETS

Flow testers : TECHNOLOGIES

ATEQ has been mastering the laminar flow technology for 30 years and simply has never encountered a technology as precise, reliable and clean.

It is by far the most stable and operates with minimum maintenance.

Laminar Flow

Sometimes a leak can be considered as a “small flow”, or a flow as a “big leak”. When your reject level is too high for other technologies, it may be necessary to use a laminar flow tester.
A flow takes place between the pressure line and the leak hole of the part.

Our instrument features a laminar flow element across which our differential pressure transducer is connected.

Every flow generates a pressure difference between the inlet and outlet of the laminar flow element, and this variation is measured by the pressure transducer.

Leak Ranges (in L/h): 5, 30, 150, 500, 1500, 4000 or 10 000 L/h
Maximum resolution: >1% of full scale
Maximum test pressure: 350 kPa
Pressure measurement: 1% of the pressure + 2 digits and 0.1% of full scale resolution
