MAG

User Manual v2.0

√

 The position on the left secures the sensor full

   of liquid.

X

 Central and right positions DO NOT guarantee

   a pipe full of liquid.

Fig. 34 | Correct (LH) and incorrect installation (central and RH)

We recommend installing gate valves downstream of the meter.

Fig. 35 | Gate valves installation

X

 In order to avoid a vacuum, always install the sensor downstream of the pump and NEVER upstream.

Fig. 36 | Avoid negative pressure
