 Krueger Sentry At-A Glance Alarms mount directly to your existing Krueger Sentry tank gauge. Can be used as a high or low level alarm by simply moving the alarm up or down the gauge. A magnetic switch triggers a flashing light that will continue to flash until the unit is reset. Includes the Alarm, a magnetic indicator for your Gauge and a 9 volt lithium battery.

With the KSALARM-DC-FL alarm the audible alarm is replaced by a flashing light and a set of dry contacts. The contacts can be used to trigger a switch turning on or off your pump or triggering your own alarm.
