'ser', under Data Streams in Device Cloud, stands for S
rror. There are two states:
0 — sensor error
1 — no error
So what would cause it to go to 0?
The 'ser' data point goes to 0 when a target can't be acquired on the sensor. This can happen for a variety of reasons:
- target too close (for SR units the minimum is 4", for MR units the minimum is 12")
- target too far (for SR units the maximum is 7', for MR units the maximum is 15')
- interference from some object in the tank (solid, liquid or gas)
- sensor isn't mounted properly
Here is an example of what 'ser' at 0 looks like:
Note the '0' value under Data.
