Leak Flow Rate Test Module, Direct Measure with Flow Sensor


TM3PQ is a pneumatic module designed for direct flow measurement for leak, flow testing, on automated systems and turntables. Its small sizes allow a really close installation to the testing product, this helps to reduce times and enhances sensitivity.

Leak flow rate test module

TM3PQ is an instrument for leak tests with direct measure of the flow rate and for the volume control of the tested product.




Delta TM3PQ ­­is a pneumatic module with direct flow measurement for leak, flow testing.
The instrument directly measures pressure and flow rate through the product being tested (filters, taps, valves, ...). Testing times below 1 second can be reached for leak or flow rate tests on small volumes. It is available the dislocated pressure reading on the tested product.

TM3PQ can measure the leak rate by using an internal volume, and also control the volume of the tested product.




TM3PQ has digital I/O interfaces for PLC connection, USB/RS485 for programming and for data collection, a software to collect and manage the tests data for PC.

This instrument can be connected and controlled by every PLC and interfaced to HMI terminal which is provided with serial lines, USB host and Ethernet interface.

The software manager permits to collect and manage tests data, to set up the parameters, programming and do SPC analysis of tests data.
