Function and system design
Equipment architectureA measuring system consists of a float switch LFL1-**-N and a transformer isolated barrier,
e. g. KFD2-SR2-Ex1.W.
Operating conditions
Installation conditions
Installation instructionsrange of application and minimum length between mounting and float:
- PVC version: ≥ 50 mm (2 inch), preferred for water
- PUR version: ≥ 100 mm (4 inch), preferred for fuels, heating oils, oily fluids
- CSM/CM version: ≥ 100 mm (4 inch), preferred for many acids and lyes

mounting:
- The float switch is mounted either from sidewards through a cable gland ≥ G1A into the vessel or
- by means of a counter weight or rods (e. g. float switch combination) from the top.
The pivot of the cable should always be horizontal.
