The Meco AST Overfill Alarm is an inexpensive battery-operated, intrinsically safe audible overfill alarm in our standard finish. Assists in overfill prevention. The Meco Alarm can be used as an overfill alarm or be configured to be used as an interstitial leak detector. When used as an interstitial monitor, Meco can custom build the probe length to meet any tank manufacturer’s specifications. As of 2016, all of our alarm models are capable of being run by both 9 volt and 12 volt power sources.
Note: For compliance in certain regions of Canada, alarms must be wired to and powered by a 12 volt source. Refer to your region's laws prior to installation.
