Report for Stacionary Tanks

Тема: Report for Stacionary Tanks

Hello.

I need help to model a report. We have some units in wialon hosting connected to level sensors to monitor stationary tanks.

I need to generate a report for my client as follows:

Date    Inicial level (first msg of the day)    Full filled    Fuell consumed    variation (filled - consumed)    final level (last msg of the day)


However I'm not managing to generate this through wialon, can someone get me something to get the result I need?

Re: Report for Stacionary Tanks

your report is not reasonable

you have filled - consumed

lets say my tank is 500 l

i consumed 300 and then i fill it with 100
the result will be negative
