Electromagnetic Flowmeter M-910
38
Operation manual
Command sets impulse width in range between 10 and 2500 ms.
<DNPD>
It represents impulse width in milliseconds. Any value in range between 10 millisecond and 2500 milliseconds can
be set. M910 confirms execution with string „Ok<cr>”. In case of query M910 returns set value in actual units.
Example:
Command „SPT100<cr>” sets impulse width to 100 ms. After query „SPT?<cr>” flowmeter returns string
„100<cr>”.
Fixed current
SFC(?)<DNPD>
Command sets fixed current in range between 4 mA and 20 mA. Current output must be set to “Fixed” mode.
<DNPD>
It represents current for “Current output” in mA. M910 confirms execution with string „Ok<cr>”. In case of query
M910 returns set value in mA.
Example:
Command „SFC10<cr>” sets current output to 10 mA (it must be set to “Fixed current” mode). After query
„SFC?<cr>” flowmeter returns string „10.000000<cr>”.
Fixed frequency
SFF(?)<DNPD>
Command sets fixed for frequency in range between 10 Hz and 12 kHz. Frequency output must be set to “Fixed”
mode.
<DNPD>
It represents frequency for “Frequency output” in Hz. M910 confirms execution with string „Ok<cr>”. In case of
query M910 returns set value in Hz.
Example:
Command „SFF1000<cr>” sets frequency output to 1000 Hz (it must be set to “Fixed frequency” mode). After
query „SFF?<cr>” flowmeter returns string „1000.000000<cr>”.
Low limit value
SF1(?)<DNPD>
Command sets low limit value PF1.
<DNPD>
It represents flowrate for low limit value PF1 in actual unit. M910 confirms execution with string „Ok<cr>”. In
case of query M910 returns set value in actual unit.
Example:
Command „SF1-10.5<cr>” sets low limit value to –10.5. After query „SF1?<cr>” flowmeter returns string „-
10.500000<cr>”.
High limit value
SF2(?)<DNPD>
Command sets low limit value PF2.
