Electromagnetic Flowmeter M921 MEATEST
46 Operation manual
Moving average samples
FTC(?)<DNPD>
Command sets number of samples for moving average calculation.
<DNPD>
Value in range between 1 (no averaging) and 20 samples can be set. M921 confirms execution with string
„Ok<cr>”. In case of query M921 returns number of samples.
Example:
Command „FTC8<cr>” sets number of samples to 8. After query „FLF?<cr>” flowmeter returns „8<cr>”.
Min. / Max. flowrates Reset
CLRMM
Command resets “Min. Flowrate” and “Min. Flowrate” values.
M921 confirms execution with string „Ok<cr>”.
Example:
Command „CLRMM<cr>” resets both min/max values.
Nominal flowrate reading
RQN?
Response contains actual flowmeters Nominal flowrate (Q
N
).
Example:
If query „RQN?<cr>” is sent, flowmeter returns response in format „80.000<cr>“ for nominal flowrate 80
(m3/h…).
Empty pipe detection
FEP(?)<CPD> { 0 | 1 }
Empty pipe detection can be enabled (1) or disabled (0).

0 Disable

1 Enable
M921 confirms command with string „Ok<cr>”.
Example:
Command „FEP0<cr>” disables empty pipe detection. User can disable this function in case user use external
empty pipe detection connected to the flowmeter’s digital input. If query „FEP?<cr>” is sent, flowmeter
