Operation manual
Firmware version
ISW?
Response contains version of flowmeter internal firmware version.
Example:
Response contains firmware version in format „1.01<cr>”.
Pipe diameter
RND?
Response contains actual flowmeter’s Nominal diameter (DN).
Example:
If query „RDN?<cr>” is sent, flowmeter returns response in format „50<cr>“ for nominal diameter 50mm.

Temperature measuring
Excitation coils temperature
ICT?
Response contains excitation coils (measured liquid) temperature.
Example:
Response contains measured temperature in format „35.2<cr>” (for 35.2
°
C).
Minimum allowed coil temperature setting
FTL(?)<DNPD>
Command sets low temperature limit in range -20 to +150°C.
<DNPD>
Presents low temperature limit.
BF
M921 confirms completion with string „Ok<cr>”. In case of a query
the
BF
M921 returns the temperature value.
Example:
Command „FTL-20<cr>” sets the low temperature limit to -20°C. If query „FTL?<cr>” is sent,
flowmeter returns response in format „-20<cr>”.
Maximum allowed coil temperature setting
FTH(?)<DNPD>
Command sets high temperature limit in range -20 to +150°C.
<DNPD>
Presents high temperature limit.
BF
M921 confirms completion with string „Ok<cr>”. In case of a
query the M921 returns the temperature value.
Example:
Co
mmand „FTH80<cr>” sets the low temperature limit to 80°C. If query „FTH?<cr>” is sent,
flowmeter returns response in format „80<cr>”.
Electronic unit temperature
IT?
Response contains temperature inside the electronic unit. This temperature should be in range -20 to +70°
C.
