Operation manual
Maximum flowrate value reading
RMX?
Response contains maximum Flowrate value.
Example:
If query „RMX?<cr>” is sent, flowmeter returns response in format „100.000<cr>“ (maximum flowrate value
indicated since last reset – command CLRMM).
Date and time of maximum flowrate reading
RXD?
Response contains time & date of maximum flowrate.
Example:
If query „RXD?<cr>” is sent, flowmeter returns response in format „10:06 15/01/2009<cr>“ (time & date of

Minimum flowrate value reading
RMN?
Response contains minimum Flowrate value.
Example:
If query „RMN?<cr>” is sent, flowmeter returns response in format „0.000 “ (minimum flowrate value
indicated since last reset – command CLRMM).
