Measurements - Import export

Cylinder series with dimensions based on ISO 15552 with an integrated position measuring system based on magnetostriction. The position sensor allows a high degree of accuracy in measuring the cylinder position. Analogue output signal 0-10 V via M 12 connector.

The high-precision calibration laboratory is accredited according to DIN EN ISO/IEC 17025 for flow calibration of flowing gases. The EP calibration laboratory is accredited by the DAkkS according to DIN EN ISO/IEC 17025:2005 for calibrations of gases in-house and on-site under the procedure number D-K-21444-01-00. We offer calibrations for gas flow measurement as well as temperature, humidity and pressure measurements. In addition, we calibrate all measured variables of the test bench directly at your site. Our experienced technicians also check the harmonious interaction of all sensors, so that the entire system is perfectly tuned. The opening of our new calibration laboratory in Asia enables us to offer you even better service internationally.

We offer test stands and measurement technology and the complete software package: LabVIEW, SPS S7, Wonderware, C Sharp LabVIEW, PLC S7, Wonderware, C Sharp Today, measurement technology is no longer conceivable without high-performance software that is tailored precisely to the application - this applies both to measurement recording and the evaluation of the recorded data, right up to the control of complete systems. For this reason, EP-E has consistently developed into a software house specializing in measurement technology over the last few years. More than half of our development department is now working exclusively in this field. We are therefore one of the few companies in Germany that can supply you with test and inspection systems where hardware and software are perfectly matched. But our team is also happy to develop suitable solutions for test stands from other manufacturers.

In order to guarantee that components such as valves, pumps, hoses and other components or component groups are free from leakage, leakage measurements are carried out. We offer leakage test benches for different pressure ranges in both the low and high pressure range.

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.

We offer you standardized complete systems for the measurement of volume & mass flows. We use measuring elements that have established themselves within previously built customer-specific test benches and convince with high measuring accuracy. The SMF® series of nozzle test benches has been specially developed for calibration with air. Critical nozzles are used as measuring elements. Up to 18 critical nozzles can be combined, depending on customer requirements. EP offers different designs for the register: Drum Design, Block Design & Register Design. Another variant is a mobile system: The EP SMF® - Mobile Flow Calibrator - a compact measuring system for flow calibration. EP Ehrler Prüftechnik manufactures single nozzles in the flow rate range from 0.005 to 2000 m³/h. In addition to our standard range, we also manufacture customer-specific nozzles that are perfectly designed for your application in compliance with DIN EN ISO 9300*.

Based on years of experience in the field of test bench metrology in the automotive industry, EP develops test bench solutions for various applications. We build test benches for testing automotive components such as heat exchangers, intercoolers, filters, valves and others. These are test benches on which e.g. supplier parts for the automotive industry are tested in production. Our specialist knowledge of the industry makes us a strong partner in this area.

We offer you a comprehensive service portfolio around your measurement technology: whether we support you in the complete project or only in sub-areas, is entirely up to you. Starting with the project planning and construction, over the commissioning and support with the CE certification up to the maintenance of your test stand - our offer extends.

The rotary gas meters GM4 and GM16 meet the highest demands for reliable and precise reference measurement of smallest quantities up to 0.01 m³/h. They operate according to the direct displacement principle (RPD - rotary positive displacement), in which two counter-rotating pistons convey a fixed volume from the inlet to the outlet of the gas meter with each full revolution. Due to the specially shaped pistons, absolutely pulsation-free operation can be achieved (patent pending). They achieve an excellent measuring accuracy of 0.5 % MW + 0.005 % EW. Both versions are suitable for operation up to 6 bar overpressure. With continuous, absolutely pulsation-free and highly precise flow measurement, the reference gas meters from Ehrler Prüftechnik are the gold standard in the field of small volume measurement. Features: Reference measurement of small flow rates Continuous and absolutely pulsation-free Overpressure operation Excellent measurement accuracy Robust & compact design
