On-Line Measuring Cabinet is suited for filter cartridges.
Press Release Summary:
Designed for on-line continuous measurement of filter cartridge efficiency, particle counting cabinet is based on testing method that allows efficiency and retention capacity of filter to be assessed continuously. Dual flowmeters record actual flows through each sensor, while computer records and processes all data and displays number of particles before and after filter. Computer also displays instant filtration efficiency or ratio.

IFTS Presents Its New On-Line Measuring Cabinet For Filter Cartridges
Chicago, May 25, 2004
To meet the quality demands of manufacturers and users of filter cartridges, France's Institute of Filtration and Techniques of Separation (IFTS) has developed a completely new particle counting cabinet. This cabinet has been specially designed for on-line continuous measurement of the efficiency of filter cartridges used in hydraulic power-transmission circuits (under ISO 16889) and in lubrication and carburation circuits (both gas and diesel) for automotive and all other internal combustion engines under ISO 4548-12(00) and ISO 19438(03). The cabinet's effectiveness exceeds the requirements of the toughest standards, such as ISO 11943(00).
In filtration, more than in any other field, performance depends directly on the assessment criteria chosen and the conditions under which performance is measured. The particle counting cabinet developed by IFTS is based on a new testing method that has been subjected to an extremely rigorous validation process. This innovative method allows both the efficiency and the retention capacity of a filter to be assessed continuously, throughout its useful life. In the future, this will enable the optimization of decisions to market filter cartridges.
Any particle counter can be fitted in this cabinet once it is equipped with two light absorption sensors - one for each side of the filter - calibrated and matched under ISO 11171 (01), whether new or already in service on a multipass test bench. A constant flow of fluid is guaranteed, whatever the degree of filter clogging, by a high precision flowmeter working in tandem with a very accurate control valve. Two flowmeters record the actual flows through each sensor. When testing automotive filters, a simple but very accurate dilution system brings particle concentration to below the particle counters' saturation threshold.
A computer records and processes all the data and displays, every minute, the exact number of particles before and after the filter as well as its instant filtration efficiency or ratio. If test bench measuring instruments permit it, they can be connected to the computer, which will then record the test parameters. New software handles all the data and produces a test report, including filter clogging and efficiency graphs, to the specific demands of each of the above standards. The user manual and test reports are currently available in French, English, German and Italian.
All instruments are delivered with a calibration certificate and the complete cabinet is approved more rigorously than is required by current standards. This equipment will be of interest to all manufacturers of filters for hydraulic power-transmission circuits and lubrication and carburation circuits as well as to end-users. IFTS is currently seeking business contacts in both the United States and Canada.
