Pump Control with Level Alarm
This application uses the Pointek ULS200 to provide pump control and one level alarm.
If the material reaches a control setpoint, the well is pumped down or up respectively. If the
material reaches an alarm setpoint, the alarm will sound until the material moves beyond the
deadband value.
