EE741
v1.0 / Modification rights reserved
The EE741 inline flow meter is dedicated for accurate metering and
monitoring of compressed air and technical gases. With three different
gauge mounting blocks, one and the same transmitter unit can be
installed on DN15, DN20 and DN25 pipes.
The thermal measuring principle and the well-proven E+E hot film
sensor element lead to best long-term stability and fast response time.
Outstanding measuring accuracy, even in the lower measuring range
is achieved by an application-specific multi-point factory adjustment,
which is performed at 7 bar (102 psi). This allows reliable leak detection
and corresponding energy savings.
The construction of the EE741 is optimized for easy installation and
maintenance.
The EE741 is user configurable and can be easily adapted to any
measuring task. The configuration can be set either using the optional display and push buttons or with the free product
configuration software EE-PCS.
