8.3.5.5 Addressing a level meter sensor
To address a level meter sensor, use the following structure:
DEV:<UID>:LVL
Where <UID> is a unique identifier that is allocated to each board, based on its SPI location.
The configuration settings for a level meter sensor are DEV:<UID>:LVL: followed by:
COMMAND OPTIONS Read/Write DESCRIPTION
MAN HVER R Reads the hardware version of the daughter card
MAN FVER R Reads the firmware version of the daughter card
MAN SERL R Reads the serial number of the daughter card
NICK R/W Sets the name of the device
STAT R Reads the alarm flags of the device (Hex Format)
NIT FREQ ZERO R/W
Sets the frequency value equivalent to 0%
Nitrogen level
NIT FREQ FULL R/W
Sets the frequency value equivalent to 100%
Nitrogen level
NIT PPS R/W Sets the read interval for the nitrogen level
HEL RES ZERO R/W
Sets the resistance value equivalent to 0% Helium
level
HEL RES FULL R/W
Sets the resistance value equivalent to 100%
Helium level
HEL PULS TIM .3 - 60 R/W Sets the measurement time for the helium level
HEL PULS DEL 0 - 60 R/W Sets the measurement delay for the helium level
HEL PULS MAG 0 - 280 R/W
Sets the excitation magnitude for the helium
measurement
HEL PULS SLOW 0-1 R/W Sets the Fast/Slow mode for Helium reading
HEL PREP TIM 0 - 1000000 R/W
Sets the preparation time for the helium
measurement
HEL PREP MAG 0 - 280 R/W
Sets the excitation magnitude for the preparation
of helium measurement
HEL LOW R/W
Sets/reads the threshold for low Helium that
activates the audible alarm
HEL HIGH R/W Sets/reads the threshold for high Helium level
HEL RFL R/W
The signals for a level meter sensor are DEV:<UID>:LVL: followed by:
COMMAND OPTIONS Read/Write DESCRIPTION
SIG HEL LEV R Helium level
SIG HEL RES R Helium sensor resistance
SIG NIT COUN R/W Nitrogen sensor pulse count
SIG NIT FREQ R Nitrogen sensor measured frequency
SIG NIT LEV R Nitrogen sensor level
