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.

EP Ehrler Prüftechnik manufactures single nozzles in the flow rate range from 0.005 to 2000 m³/h with highest accuracy up to 0.12 % MW. 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*. Nozzle holders including sensor connections are available for all nozzle sizes for installation in customer applications. Different nozzles can be combined to set different flow rates, allowing a high number of different flow rates to be generated quickly. With 8 critical nozzles, for example, 2^8 = 256 different flow rates can be generated. A binary staggering of the nozzles ensures an even coverage of the volume flow rate range.

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*.

We offer you standardised 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. We develop and manufacture Venturi tubes and nozzles as individual components or as VMF® complete systems. The VenturiMasterFlow® measuring system, VMF® for short, is used for the precise measurement of air or gas volume and mass flows of 100,000 m³/h. The core of the VMF® system is the FlowProcessor, a PC system with the corresponding data acquisition hardware. Venturi nozzles convince by a low remaining pressure loss and are suitable for flow measurement of gases with high temperatures. The software developed under LabVIEW is operated either via touch screen or with mouse and keyboard.

We offer you standardised complete systems for the measurement of volume & mass flows. The EP LMF®-LaminarMasterFlow® is a complete system for high-precision flow measurement of gases and air. The LMF® system consists of a flow processor, a Laminar Flow Element (LFE) as measuring section, a cable set and a sensor package. The flow measurement is performed by means of Laminar Flow Elements (LFE), which are available in different sizes and cover a measuring range from 0.01 to 700 m³/h. (optionally up to 4000 m³/h).

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.

with adjustable humidity and temperature to simulate the environmental conditions of a test specimen (e.g. household appliances, heating technology) The basis is a standard or climatic chamber (e.g. test kitchen, environmental simulation) with adjustable air humidity and temperature. On the basis of decades of experience in automotive test engineering, EP-E developed a concept in which the air flows in a circle (loop design). The result is a very excellent homogeneous temperature and humidity distribution. Through precise temperature and humidity control, it is possible to set different combinations of air conditioning and thus precisely adjust the required test conditions. The determination of the air flow (exhaust air volume) is carried out via a measuring section with the use of Laminar Flow Elements (LFEs). In order to determine the volume flow, pressure and temperature sensors are used to determine the air volume flow of the climatic chamber(s).

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.

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.

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.
