Address Size Type Value Description Values
1009 1 Char
SOS_LIQUID_SPEC
GRAV_SEL Selects use of pre-defined SOS Specific Gravity or a
custom value entered in 'SOS Specific Gravity'.
0 = 0.997 (Water), 1 = Custom
1010 1 Char
SOS_LIQUID_SOS_
SEL Selects use of pre-defined SOS Liquid Sound Speed or a
custom value* entered in 'SOS Liquid Sound Speed' 0 = 4910.4 ft/s (Water), 1 =

uses 4-20mA input channel 2, Protocol uses values
written to register 5003.
0 = Fixed, 1 = Sensor 1, 2 =
Sensor 2, 3 = Protocol
1012 1 Char
TLF_PRESS_INPUT
_SEL
Selects the source of the pressure used in GVF
calculations. 'Fixed' uses 'SOS Process Pressure',
'Sensor 1' uses the 4-20mA input channel 1, 'Sensor 2'
uses 4-20mA input channel 2, Protocol uses values
written to register 5001.
0 = Fixed, 1 = Sensor 1, 2 =
Sensor 2, 3 = Protocol
1013 1 Char SOS_TEMP_UNITS

Temperature' degrees.
0 = C, 1 = F
1014 1 Char
SOS_PRESS_UNIT
S
Selects units used for input of 'SOS Process Pressure'. 0 = PSIg, 1 = kPAg, 2 = BARg
1015 1 Char ALTITUDE_UNITS Selects units used for entry of 'Altitude'. 0 = ft, 1 = m
1016 1 Char DISP_LINE1

1020 1 Char CUST_VOL_UNITS Selects volume units used in calculation of a custom unit.
0 = m^3, 1 = l, 2 = gal, 3 = m, 4 =
ft, 5 = iga, 6 = ft^3
1021 1 Char CUST_TIME_UNITS Selects time units used in calculation of a custom unit. 0 = d, 1 = h, 2 = m, 3 = s
1022 3 Char CUST_VOL_LABEL
