Tailor made to your specifications: flow measurement systems
Our flow measurement systems based on differential pressure (orifices, Venturi nozzles) with the required inlets and outlets are made of stainless steel, just as are the systems with supercritical Laval nozzles.
We develop and manufacture special nozzles as tailor-made products in the material of your choice. We can deliver measurement and calibration standards with Laval nozzles with utmost precision – measurement inaccuracy to 0.14% of measured value (k=2). The measurement ranges for these systems start at approx. 1 l/h (10-3 m³/h). With an appropriate compressor (vacuum pump), up to 10,000 m³/h are possible. A test bench with 12 Laval nozzles and dual nozzle grading allows to set 212 discrete flow steps (i.e. 4,096 step) in flow increments of the smallest nozzle – at highest accuracy of up to 0.14%.
Our subsidiary EP Instruments (EP) is specialised in on-site calibrations of various flow measurement systems (irrespective of the manufacturer). This ensures that the measuring element is calibrated in the installation condition when it is subject to real influences and not only to laboratory conditions without environmental influence.We also calibrate measurement systems with air at temperatures of up to 500 °C.
