Installations
To install the flow switch correctly follow these instructions:
-Select the blade marked with the diameter of the pipe in which the
switch is to be installed;
-Remove any extra pre-fitted blades for larger diameter pipes by
unscrewing the 2 blade attaching screws;
-With pipe diameters of 3” (DN 80) or above, all the pre-fitted blades
must be attached in ascending order with the long blade being cut
to the size corresponding to the desired pipe diameter;
-Fit the flow switch to the pipe, carefully observing the direction of
flow indicated by the arrows stamped on the cover and on the switch
mounting plate. When fitted, the distance between the upper surface
of the pipe and upper surface of the switch mounting plate should
be 3 1/8” (80 mm);
-The tee connection in the pipe can be formed by the direct welding
of a threaded socket;
-This also applies to a 1” (DN 25) diameter pipe, as the blades are
designed to be contained in these smaller dimensions.
-It is however advisable to check that the weld is free from burrs on
the inside so that the blade can move freely in the tee connection;
-Whenever possible the flow switch should be installed in the
vertical
position to avoid deposits of impurities which may cause it to
function incorrectly.
