Flow and Leak Tester


T3LPF is an instrument for flow test with mass flow sensor but also for leak test with absolute pressure decay measurement. Its pneumatic circuit that can perform both flow and leak test, makes this instrument useful in many applications.

Flow and leak tester

T3LPF is an electro-pneumatic instrument, designed for air flow tests at a programmed pressure, but it is also able to perform leak tests with absolute pressure decay measurement.




T3LPF is extremely flexible in terms of applications where it could be used, and suitable in all industrial segments, on testing benches, production lines or fully automatic systems. The screen interface, with colour display and real-time view of testing, make programming and use simple and immediate.




T3LPF has digital I/O interfaces to PLC connection, USB host, two serial lines RS485/RS232 for PC, Ethernet interface. The control of external automations, the interface with barcode, QRcode readers and printers make T3L a complete and suitable instrument for the most modern production applications. The software manager dedicated permits to collect and manage data of the tests, to set up the parameters programming and do SPC analysis of tests data.

  • Flow measurement with mass sensor full-scale ranges: between 50 cm3/min and 300 l/min
  • Resolution up to 0.01 cm3/min
  • Leak test with measure of pressure decay: full scale up to 6 bar
  • Resolution up to 0.1 Pa
  • Full colour 7” LCD display – graphic test view
  • Fully Interfaceable: Digital I/O for PLC – USB for PC – Serial lines RS485/232 - Ethernet
  • Test Data Storage on USB pen drive or LAN/Ethernet/Profinet
  • External Automations and Devices control: printer, barcode and QRcode reader – remote control keypad – air filters
  • Software Manager, dedicated for T3 modules management data storage and statistical process, is available.
