Air flow meter
Suitable for pipe diameters DN15, DN20, DN25. The new, compact EE741 in-line flow meter measures accurately the consumption of compressed air and technical gases; e.g. nitrogen, oxygen, helium, CO2 or argon. Thanks to the modular design, one and the same transmitter can be used for three different pipe diameters (DN15, DN20, DN25). To do so, the transmitter is simply combined with the appropriate gauge mounting block.
Easy installation and removal:
The gauge mounting block is permanently mounted at an appropriate location of the pipeline. The transmitter can be installed and removed without disassembling the pipework and with only a short interruption of the air or gas flow. This construction facilitates the periodical calibration of the transmitter and its temporary use at several measuring points
High resistance to contamination:
The EE741 employs the well proven E+E thin-film sensor, which operates on the thermal anemometer principle. The advantage: excellent long-term stability and short response time. The thin-film sensor is highly insensitive to contamination. Also, the operation principle eliminates the need for additional pressure or temperature compensation. The multi-point factory adjustment at 7 bar (102 psi), which is the common pressure of the compressed air supply, leads to best accuracy even in the lower measuring range.
