Notes:
1. Register byte order is big-endian
2. Float values are formatted according to IEEE 744 32-bit representation
3. Flow total has a range from 0 to 999999.9
4. Registers corresponding to parameters, which are not configured to be measured or calculated,
contain random values.
5. HM 3000 channel outputs are in order of channel configuration as per HM 3000 settings. Refer to
Chapter 21.2.1 for ordering configured channels.
WARNING: The outputs listed in this table are for illustrative purposes only.

23.2.3 SDI-12 Mode
The SDI-12 implementation complies with V1.3 of the SDI-12 specification.
Configurable parameters are:
• Address (‘0’-‘9’, ‘A’-‘Z’, ‘a’-‘z’)
• Which measurement results to provide
On receiving an SDI-12 Measurement command, the FloSI replies with
notification that the measurement results are immediately available. Upon
receiving a Send Data command, the FloSI returns the currently available
result data which it has been configured to provide.
THE FOLLOWINg SDI-12 COMMANDS ARE SUPPORTED:
