Opp's I made a Remote Tank Inventory Application (Part 2)
This is our first project in Node Red. We start to look at more industrial applications using 4-20mA signals for level measurement sensor, in this example we use a Siemens SITRANS LR110. This project also uses a Sequent MicroSystems IO card with a Raspberry PI.
Part 2, we range all of the process values, Level, Distance, & 4-20mA, push this data into global memory and build a Node Red Dashboard.
The following Nodes are used, Range, Change, Gauge UI
The goal is to build a project that can be utilised to monitor vessel content remotely and to aid with stock control.
