Compatible data logger (e.g. Jellox )

Functions and components:

• VEL‑R‑5

  The device is a portable measurement instrument approved for ex zone 0/1 used for determining the surface velocity. The transmission of the measuring command to the VEL‑R‑5 and reading out the determined measurement value from the VEL‑R‑5 are realised via a local radio connection.

• Compatible data logger (e.g. Jellox )

  Data logger that cyclically starts the water level measurement and then records the generated measurement values. A list of compatible data loggers is provided in the chapter Compatible data loggers.
