| Function and system design | ||
| Equipment architecture | A 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 instructions | range 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. |
