The industrial landscape is characterized by a growing demand for precision, safety and reliability in production processes. In this context, leak meters emerge as fundamental tools, playing an important role in the quality control and testing processes of products that must guarantee perfect watertightness.

 

Operation

Pressure decay leak meters work by measuring the Δp/Δt gradient, evaluating the change in pressure within a pressurized part over time. These tools are divided into:

  • absolute systems, which directly measure internal pressure;
  • differential systems, which compare the pressure variation between the piece being tested and a sample piece.

These instruments operate through four phases: filling or emptying the piece, pressure adjustment, measurement of pressure variation and discharge.
The second approach offers a higher level of precision and sensitivity to detect even the smallest leaks at high pressures, ensuring high standards of quality control.
There are also leak meters with direct flow measurement, i.e. very low flow meters, which in some particular applications can guarantee an advantage in terms of cycle time compared to pressure decay measurement.

 

Specific Applications

  • Biomedical sector: in this category leak meters are irreplaceable tools for guaranteeing the safety and effectiveness of many devices. In hollow fiber dialyzers, for example, they are used to test the tightness of the body, heads and fibers. Their application in hemodialysis pumping units requires equally high precision in leak detection; their use is therefore essential to avoid risks for the patient due to blood contamination. Even more stringent requirements are required for the compliance of implantable pacemakers, for example.
  • Appliances sector: in the production of detergent and rinse aid dispensers for dishwashers, pressure switches and water pumps for washing machines, leak meters play a key role in ensuring the tightness of these components. Their application in these contexts is essential to prevent unwanted detergent or water leaks and ensure the correct functioning of household appliances, helping to extend their life.
  • Automotive sector: in this branch their use is wide and varied. From the fittings for the air conditioning system to the exhaust manifolds, passing through the lights and pressure sensors, hundreds of components installed on board vehicles must be subjected to leak tests to check that the gaskets, glues and welds are compliant and guarantee the air and water tightness required by vehicles that can be used in unfavorable environmental situations.

  • Industrial Sector: the application of leakage meters extends to the production of thousands of components such as shock absorbers, industrial filters, valves, etc. Their presence in leak testing processes helps to intercept critical non-conformities to ensure the safety and reliability of industrial supplies.
