One table to save all records vs create one table each day
Avoiding separate tables by date would be best. Besides the benefits you mentioned, performance will likely be better too.

If each table has a row for the same ID and Timestamp (e.g. a device that reports all 5 readings at the same time), you could have a single table with ID, Timestamp, pressure, flow, volume, temperature, and distance. 

You might also consider using columnstore and partitioning by date for maximum performance and manageability (respectively).
