RFO high-performance flow tester


RFO flow measurement
“RFO” technology is the latest evolution in continuous capacity measurement instrumentation, specifically for applications with high variability of flow values and the need for very high adjustment of the pressure, to compensate those different load losses.
Typical applications include leak testing of boiler gas-tight chambers, car, tractor or lorry cabs, chimney flues, etc…where the test pressures requested are very low (0.5…10 mbar) and therefore pressure adjustment must be extremely stable and precise.

Very low pressure adjustment (0.5…10 mbar) Automatic electronic regulator “Real Flow Output” pressure compensation

Advanced interface.
For us, the T9000 series is the most technologically forward of measurement systems, equipped with an advanced interface, useful for analysis and research during the prototyping or pre-series phase, as well as for production line testing.
The big, 7” colour display set in a capacitive glass panel allows total interaction with the internal menus and the main screen. The "smart" testing archive contains daily and monthly analysis functions and those specifically for each test program, to keep the level of quality of your products under control.

Limitless connectivity.
The new T9740 equipment includes ports for the USB slave, RS232, RS485, Profinet, EtherNet IP and EtherCAT. Assembly may also include an optional Ethernet port and a 26-pole connector with 4 inputs and 8 outputs, which are completely programmable, for interfacing with the external valves, safety barriers, switches, etc...
The front panel has a master USB port assembled on it for connection to a USB key to save the tests conducted, backup/restore parameters and upgrade tool firmware.
The connection to thermal printers, barcode/data-matrix readers and markers takes place automatically using an internal menu.

Top category technology.
We decided not to make compromises when equipping the T9740, assembling the best components currently on the market, such as the piezoelectric electronic regulator which guarantees stable and repetitive adjustment, or the solid-state sensor with a vast reading range, or the specific valves for this model, with a life estimated in tens of millions of cycles.
All these advantages give never before seen precision performance, stability and accuracy.
The measurement resolution starts at 0.1 cc / min based on the full scale, ranging from 10 to 100 l / min, with maximum pressures of 100 mbar.
Automatic pressure regulator Measurement up to 100 l/min Resolution starting from 0,1 cc/min

Made to measure pneumatic section.
To avoid overheating due to long activation times of the filling circuit, we have designed particular, high capacity pneumatic valves, which not only work in hot temperatures, but also quickly fill the piece being tested, making the T8710 also suitable for testing on parts with significant volumes.
All of the above, while maintaining ForTest's historic reliability.
Heat-proof pneumatic valves High filling speed No periodic maintenance
