Insertion Flowmeter for compresseci air and gases Riels EE776 flow meter is based on the thermal mass flow measurement and is ideal for measuring the flow of compressed air and gases in pipes from DN50 (2") to DN300 ( 12"). With the EE776,the consumption of compressed air; nitrogen, C02 or other non-corrosive and non-flammable gases can be measured up to a pressure of 16 bar (232 PSI),for example. Patented non-return protection for secure mounting The EE776 flow meter set new standards in terms of safety and easy assembly.The patented non-return protection combines three functions in one device: • Non-return protection The sensor can only be pushed in one direction during installation.The sensor cannot return By means of an encapsulated O-ring, no compressed air can escape under pressure during • Precise positioning The precise positioning with respectto immersion depth and orientation is easyto perform, guaranteeing accurate measurement results. The high measurement accuracy of 2.5% from reading results from the application-orien- ted factory adjustments, which are undertaken at 9 bar (130 PSI) pressure. For optimum adaptation to different measurement tasks, you can choose between two measuring ranges 0.2... 100 Nm/s (40... 19685 SFPM) or 0.2...200 Nm/s (40...39370 SFPM) and two different probe lengths with a maximum immersion depth of2l5 mm (8.4") or 365 mm (14.4"). The inner diameter of the distribution pipe which is measured can be entered via the USB port and the included confìguration software. Two signal outputs are available to output the measured values. Depending on the applica- tion, these can be confìgured as an analogue output (current or voltage), switching output or pulse output for consumption measuring. An optional tapping sleeve allows the subsequent assembly of the sensor into existing pipeli- nes, and this without interrupting the supply systems. Typical Applications Measurement of consumption of compressed air Mass flow measurement of industriai gases ■ Non-return protection for secure mounting ■ Assembly/disassembly under pressure without flow interruption ■ Easy and accurate positioning ■ Wide measuring range up to 200 Nm/s (39370 SFPM) The EE776 flow meter has a modular design and consiste of probes (I) and evaluation electronics (2).The probe includes sensor and measuring elec- tronics, in which the factory adjustment data is stored. The evaluation electronics communicates digitaily with the probe and can be located up to 10 m (32.8 ft) from the probe.
