Inlet and Outlet Measurement Path

For measurement accuracy according to product specification, the EE741 flow sensor shall
be located as far as possible from flow disturbances caused for instance by pipe reductions
or expansions, bends, T-pieces, valves or sliders. This can be accomplished by observing a
minimum inlet and outlet path length, which depends on both the nature of disturbance and the
pipe diameter. This applies to mounting the EE741 in the gauge mounting block as well as in the
gauge mounting block with flanges.
• The flow sensort shall be located before valves or sliders.
• With light gases the inlet paths need to be extended.
