Left to Right Flow Example in 1/4 and 3/8 inch tube tees
For optimum sensitivity in low flow applications, probes should
be installed with the “A” (Active) sensor positioned upstream.
Horizontal lines: gas or liquid.
Vertical lines:
gas - flow must be down
liquid - flow must be up
Right to Left Flow Example in 1/2 inch or greater tube or
pipe tee
Probes mounted into 1/2 inch or greater tees are installed with
the sensors positioned perpendicular to the flow path in the
tee. “A” (Active) should be facing up in side mount horizontal
configurations. These sensors may also be marked with a flow
direction arrow.
