ATEQ has been mastering the laminar flow technology for 30 years and simply has never encountered a technology as precise, reliable and clean. It is by far the most stable and operates with minimum maintenance.       Laminar Flow A flow takes place between the pressure line and the leak hole of the part. Our instrument features a laminar flow element across which our differential pressure transducer is connected. Every flow generates a pressure difference between the inlet and outlet of the laminar flow element, and this variation is measured by the pressure transducer. Leak Ranges (in L/H): 5, 30, 150, 500, 1500, 4000 or 10 000 L/H Maximum resolution: >1% of full scale Maximum test pressure: 350 kPa Pressure measurement: 1% of the pressure + 2 digits and 0.1% of full scale resolution
