Leak Flow Rate Tester, Direct Measure with Flow Sensor


T3LPQ is an instrument designed for leak tests with the direct measure of the leak flow rate. Its fast tests make this instrument one of the products with best stability and precision in measurements.

Flow and leak tester

T3LPQ is an electro-pneumatic instrument, designed for testing air tightness by direct measurement of air leakage.




The balanced pressure method allows to obtain measurements that are independent from the tested volume and it offers the best stability and precision. The touchscreen interface, with a colour display and a real-time view of the tests makes the programming and the use simple and immediate.

T3LPQ is suitable for all industrial segments, on testing benches, in production lines or in fully automated systems.    




T3LPQ 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.

  • Leak measurement with mass flow sensor ≥ 2 cm3/min up to 100 cm3/min
    Resolution up to 0.01 cm3/min 
  • Electronic regulation of the test pressure from 5 mbar to 1 bar, 2 bar depending on test conditions
  • Optimal pressure balance for tests that do not depend on the product volume (≥10 cc to 2 liters)
  • 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 – external valve for volume check for a quicker filling phase – air filters
  • Software Manager, dedicated for T3 modules management data storage and statistical process, is available.
