EP Ehrler Prüftechnik manufactures LFEs in the flow rate 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 corresponding mounting kits are available for all sizes for installation in customer applications. The achievable measuring accuracy depends largely on the sensor technology used, in particular the differential pressure sensor. When using high-quality sensors, measuring accuracies of up to 0.5 % MW can be achieved with LFEs in the measuring range of 1:10. In order to cover a very wide measuring range without restrictions in measuring accuracy, LFEs with overlapping flow ranges can be combined in one measuring setup. Alternatively, LFEs with correspondingly lower measurement accuracy can also be calibrated for an extended measurement range up to a maximum of 1:100.

Large heat and flow meters are often used continuously for decades after an initial calibration at external test benches. A recalibration of these meters within their actual operation conditions was not possible so far. In the best case scenario those flow meters are unmounted and recalibrated on an external test bench. Drawback of this method is an interruption of supply in addition to its already high costs. Furthermore, calibration conditions can differ greatly from actual operation conditions compared to test bench conditions, so even if calibrated, the measurement uncertainty in operation remains fairly unknown. This often leads to more difficult fluid distribution optimizations and leaves billing fairness to a gamble. More precisely measured values of flow sensors may uncover hidden saving potentials within the fluid distribution system and allow more exact performance indicators, improving energy efficiency.

The test bench is designed for calibration with critically operated nozzles of domestic gas meters or others such as diaphragm gas meters, ultrasonic meters, thermoelectric gas meters. The test bench is specially designed for the calibration of domestic gas meters (bellows gas meters, ultrasonic meters, thermoelectric gas meters). The test bench is modular - 1x6 to 4x6 clamping positions for the gas meters can be combined. Due to the modular design 1 to 12 gas meters can be tested simultaneously. In parallel, up to twelve additional test pieces can be adapted, run in and leak tested. A magazine consisting of three critical nozzles is used as flow transmitter. Optionally, a nozzle drum with nine combinable nozzles can be used. This allows the generation of up to 512 different flow points with highest accuracy.
