Page 9: Safety Instructions For This Device
For units with a dead weight of 30 kg or more, the customer must provide adequate support (e.g. via a spring suspension device, etc.). This can be attached to the holding strap/eyelet on the device. -
Page 10: Contents Of Packing
Caution Note! For displays weighing 30 kilograms or more, the customer must provide sufficient support (e.g. by spring hangers or similar). Caution 3.1 Intended use Remote level gauge: The remote level gauge type GS can be used for every steam generator according to TRD 401 except continuous steam generators. -
Page 11: Explanations
Explanations 4.1 Scope of supply The type FA GS is used to indicate the water level of steam generators. 4.2 Function The level gauge works according to the physical low of the communicating tubes. The geodetic pressure difference of two water columns is transferred to a transparent separating blue liquid in the remote level gauge. -
