Installation of Flow Switch
As stated on Page 2-10, Eaton recommends the installation of the flow supervision in the
liquid cooling system. If requested, Eaton delivers the flow switch as an option. The
application of the flow switch as well as notes concerning its installation are given below.
About Flow Switch Installation
Eaton recommends mounting the flow switch on the inflow side of the system (see
Figure 2-10. Pay attention to the direction of flow. The switch reaches the highest accuracy
when it is mounted in horizontal position. If mounted vertically, the mechanical sensor is
affected by the Earth’s gravity which reduces the accuracy according to the data given in
Table 2-13.
