  • Profile

    CME and its predecessor company have been successfully supplying flow calibration systems, transfer standards and Oxygen Test Stands to the U.S. Military and industrial calibration laboratories for more than forty years.We have concentrated on applying our laminar flow technology to high accuracy gas flow measuring. We have emphasized merging our gas flow expertise with the rapidly changing electronic technology to produce SMART, user-friendly gas flowmeters, calibrators and test stands.The flow of the test gas through the linear restrictor(s) creates a pressure difference (differential pressure) between the upstream and the downstream pressure taps shown in the cut-away drawing. The differential pressure is directly related to the flow and viscosity of the gas, according to the 140-year old Hagen-Poiseuille law.The flow inside the element is laminar (not turbulent) so that as flow rate is decreased the Reynolds Number is decreased and the flow is even more laminar.

    All of the flowmeters, flow systems and flow calibrators made by CME utilize these Laminar Flow Elements CME strongly advocates the use of SMART flowmeters, systems and calibrators to meet the increasing demand for greater accuracy of measurement in test and calibration. CME SMART flowmeters provide both volumetric (actual) and standard/mass flow measurements.To maintain the accuracy of the Laminar Flow Element’s calibration, it is necessary to measure the temperature and pressure of the gas flow stream. CME SMART flowmeters have all components calibrated together, as a system, and dedicated flow computers automatically make all flow calculations. This eliminates the need for manual calculations and additional operator training CME SMART flowmeters have all components of the measurement calibrated together and dedicated computers automatically make all corrections and compensations. That’s why CME can guarantee an overall system accuracy with the minimum degradation of accuracy and possibility of error and still provide both actual flow rates and standard flow rates
