Low Level Alarm Switch
This application uses the Pointek ULS200 to provide one or two low level alarms.
If the material can fall below the unit's range, the Pointek ULS200 loses the echo,
and if prolonged, defaults to fail-safe operation. The fail-safe default should be set to
suit the application.
fail-safe = 1, 2, or 3

Dual Pump Control
This application uses Pointek ULS200 to provide a control output when the process material
rises to a high level.
Typically, wet wells are used to temporarily hold storm and/or waste water. When the water
surface reaches a high level setpoint, the wet well is pumped down. The process material will
be pumped down by the deadband value to another setpoint where the control will turn off.
