Programming: When used in this manual this refers to the setup and entry of the user
configuration into the LevelCom 100.
Purge: The LevelCom 100 periodically applies compressed air to the bubbler pipe to ensure
it is free of liquid. This purge can also help keep the end of the bubbler pipe clear of
obstructions. The LevelCom 100 program can be configured to purge the bubbler pipe on
demand or at set times. The length of time allowed for a purge is adjustable from 5-120
seconds.
Relays: The LevelCom 100 is available with 2 optional “Form C” relays. These relays can
be used for alarm or control purposes.
Sense Line: The sense line is the system including the bubbler pipe mounted inside the
tank and the interconnecting tubing leading back to the LevelCom 100. The LevelCom 100
measures the pressure on this tube to calculate the depth of the liquid in the tank.
Specific Gravity: Specific gravity is a user-defined parameter in the program. This
parameter is used to convert the static pressure reading from the bubbler pipe into a depth
reading. Automatic Specific Gravity sensing is available as an option. If the LevelCom 100
is being used to monitor a tank that is used for various products with differing specific
gravities then we encourage the user to consider adding this option.
SURE? “SURE?” appears when the user has entered a section of the program that will
erase or overwrite the configuration. The LevelCom 100 queries the user to allow time for
the user to consider if he is certain of his actions. If “SURE?” appears on the display at any
point in programming and you do not know why - Don’t press ENTER!
