Hi learned guys, I do not like to re-invent the wheel and hence would appreciate if someone can point me in the right direction:
A road tanker (B Double or it could be an Isotainer) is being filled with hot Ammonium Nitrate solution (Temp: 130 to 135 deg C, has to be less than
140 deg C to comply with ADG code). We wish to install a suitable instrument (preferably non-contact type and attached to the filling arm) that will detect and close the filling valve if the level in the road tanker rises above safe fill level.Is there any other alternative solution available to prevent overfill and subsequent cleaning up of AN solution spills? One technology that comes to my mind is having a weigh bridge under the loading station so that the road tanker can be Tared and filled at the same location.
Kindly be aware that AN solution will start to solidify almost immediately if the temperature is decreased (less than tanker fill temperature). Thanks in advance for all suggestions and pointers. Regards, Raj Sreenevasan
