4. Operating Principle The Plastic Flow Meter model: KSM operates according to the variable area principle, in which the float is free to move without friction inside the measuring tube. The reading edge corresponds to the larger diameter of the float. The standard flow meter is equipped with a scale for water (+20°C), a percentage scale, O-rings, 2 adjustable set-point indicators and a rail for accessories;...
Protect the measuring tube from external damage. Avoid pressure peaks in the measuring tube, e.g. from sudden surges or stoppage of flow. The units with bistable reed switch may not be installed within an inductive field. If possible, immediately after making mechanical connections, check whether the connections are properly sealed with no evidence of leakage.
8. Operation In order to initialise the bistable switching function, it is essential that the float-travel activates the contact once in each direction. Adjustment of limit-values The switch-point can be adjusted to the desired levels by using both red sliders as reference points.
