Atkinson Equipment Combined Low Level & Overfill Alarm
Battery or mains powered versions available.
Simple operating principle; Float switches are suspended inside the top of the tank and bottom of the tank. These are factory attached to the alarm with cables of 2m in length. Once the level of fluid in the tank the raises the float on the overfill probe, an audible alarm will sound, similarly if the float drops to the low level sensor this will also cause the alarm to sound.
