Q: When using the Export Data Services API to obtain a range of reads, why do we sometimes see results like this?
“Flow_Time”,”Meter_ID”,”Flow”
“2016-10-25″,”15799519″,”0.0”
“2016-10-25″,”15799521″,”0.0”
“”,”15799502″,””
Similarly, when exporting data via the Monitor page>Actions menu, we sometimes get columns that only include double quotes (“).
Why is this happening?
A: It may be easier to visualize the data in your first example in table form:
| Flow_Time | Meter_ID | Flow |
| 2016-10-25 | 15799519 | 0.0 |
| 2016-20-25 | 15799521 | 0.0 |
| “” | 15799502 | “” |
In both cells that contain nothing but double-quotes (“”), the system was unable to get a reading for Meter 15788502 on the date you requested reads (2016-10-25).
The same thing has occurred in the export performed via the Monitor page. That is, the system was unable to get reads for Meter_ID 15799502 on the date of your export, leaving many fields blank (remember, AquaCUE inserts quotes when the Quoting Options>All default is used).
