Laminar Flow Elements
Flow measurement elements with highest accuracy
EP Ehrler Prüftechnik manufactures LFEs in the flow range from 0.012 to 4000 m³/h. In addition to the standard range, EP offers customer-specific LFEs that are perfectly designed for your application. Suitable inlet and outlet sections and the associated mounting accessories are available for all sizes for installation in customer applications.
The achievable measurement accuracy depends significantly on the sensor technology used, in particular on the differential pressure sensor. When using high-quality sensors, measurement accuracies* of up to 0.5 % MV can be achieved with LFEs in the measuring range of 1:10. In order to cover a very wide measurement range without restrictions in measurement accuracy, LFEs with overlapping flow ranges can be combined in one measurement setup. Alternatively, LFEs with correspondingly lower measurement accuracy can also be calibrated for an extended measurement range up to a maximum of 1:100.
*Higher measurement accuracies on request
Application examples
Calibration of flow meters, e.g. gas meters, LFE, Venturi nozzles, MFM, MFC
Determination of characteristic curves for valves, fans, filters, etc.
Flow measurement, e.g. for intake air measurement on engine test benches or in sample test benches for tank venting valves
Production monitoring of components
