The Loon (Product Manual)

The Loon was designed to monitor a tank level and record/indicate changes in
that level. This unit has three different ways of outputting the current tank level.
The first is an Up Pulse and Down Pulse Output. Two open collector outputs can
indicate either a positive or negative direction of level movement. Each pulse
indicates a specific level change of a certain distance. Communications are the
second way that the Loon can transmit a level. Using an SV Bus the Loon can
have values loaded to it and values received from it. After the host has loaded a
value to the Loon, it can keep reading it for constant level updates. An isolated 4
to 20mA current output is also available. The output will be scaled between a
low and high level which can be entered via the SV communications bus. A
battery input is also available on the Loon. In normal operating conditions, the
battery will be trickle charged, but if power fails, the battery will sustain power to
the unit to monitor the level until main power is returned.
