Check weigh scale
The digital check weighing system with segregation unitis designed to check the gross weight of a filled LPGcylinder and reject the cylinder from main stream on toa loop conveyor if the gross weight is more or less than
the stipulated value. The electronic check scale isprogrammed in such a way to subtract 14.2 Kg or 19 Kgfrom total weight of cylinder and the tare weight willbe displayed. Operator has to compare the displayed
tare weight value with the tare weight value punchedon the cylinder and if the value is beyond thepermissible limit, the cylinder will be rejected.
