No.1 Transfer of drain

No.1 Transfer of drain by the Drum Level Communicator

[ Problem Point ]

One operator is doing transferring in a drain by himself,

so it isn’t possible to see through until it’ll be fill up the drum.

[ ⇒Kaizen Point ]

Started using the DLC-100B  Bell type.

So loud 80 horn Bell Type.

Can work backwards and do not worry.
