Achieve Maximize Efficiency and Productivity with CTS Test and Reclaim Systems

Mass Flow Test Systems & Instrumentation

Mass flow testing is used to determine the mass flow rate, which is the mass of a substance (liquid or gas) flowing past a fixed point per unit of time. Mass flow systems measure the volumetric flow of air passing into or through a product per unit of time (e.g. cubic centimeters of air per minute). This measurement is used for the leak testing and blockage (occlusion) testing of devices.
 
Mass flow leak testing is important in determining the integrity of parts and components. It is a non-destructive form of testing that is highly effective for detecting small leaks and is used for the testing of gas meters, appliances, exhaust systems and more. Mass flow testing is used for products of various sizes and is suitable for components that operate using gas or liquid.  
 

Mass Flow Testing for Measuring Performance Characteristics

For over 30 years, Cincinnati Test Systems (CTS) has been a leader in the design and fabrication of mass flow testing technology. We provide turnkey mass flow leak testing and air flow testing solutions designed to accommodate a range of testing requirements and production environments.
 
Through extensive application experience, our engineering team has developed comprehensive knowledge of the factors that must be considered when integrating a mass flow test instrument into a production testing environment.
 

Selecting the Right Mass Flow Leak Testing Equipment for Your Application

To get the most accurate test results, it is critical to know the best mass flow testing technology to use for your application, how to obtain measurement repeatability, and how to minimize test noise caused by environmental factors. The range of the flow test system is also a key consideration for optimum precision and repeatability.

Selecting the right mass flow instrumentation for your application is vital to getting the most accurate results. The mass flow leak testing system should provide a flow meter range that delivers the right level of sensitivity for your application

Mass Flow Leak Testing Technology for Challenging Production Environments

What really sets CTS apart from the competition is our ability to offer application-specific, turnkey systems that meet the unique needs of our customers' challenging production environments. We will work with you to determine the best mass flow testing solution for your needs.
 
  • Mass Flow Testing: Technology that uses a mass flow meter to determine the rate of a fluid or gas flowing. Flow testers are typically used for calibration, occlusion testing, and critical flow requirements. Also commonly used in leak detection instruments.
  • Mass Flow Path Size Testing: Accurate technique used to determine restrictions in test parts. Technology includes pneumatic and hydraulic media.
  • Mass Flow Leak Testing: Widely used for larger volume or highly elastic parts. These leak detection instruments measure and record the flow of makeup air/gas required to compensate for air/gas loss from a leak at a constant pressure over a fixed time period.
  • Mass Flow Leak Standard Testing: This flow testing method allows non-leaking parts to read near zero by tarring out conditions that result in flow not attributed to leaking.
  • Differential Mass Flow Leak Testing: Similar to mass flow testing, but utilizes a reference volume of similar or exact design or volume of the part under test to help eliminate additional flow characteristics that are not associated with a leak like adiabatic conditions. This flow test method allows more stable test pressures of makeup air during test, and typically offers improved repeatability depending on the application.
