SENTINEL
The essential Acoustic Level Indicator
In the control of liquid storage systems, visual and audible alerts related to filling and emptying states ensure safety and efficiency. Timely notifications to operators and the activation of supervision procedures are essential for the safety and proper functioning of the plant.
Sentinel is a level acoustic notifier designed to monitor and emit sound alerts in case of liquid deficiency or excess. For its proper operation, it requires connection to a float switch. This device is intended to be used in applications with the presence of water storage solutions and, more generally, can be used wherever a float switch is present. Sentinel is powered by mains voltage or through a rechargeable internal battery of 9V-110mA.
There is also a variant called Sentinel 2, which features a clean contact output relay. This relay allows the activation of a remote alarm signal and requires power supply from the electrical network.

Applications
There are various applications where having auditory and visual level feedback is useful and indispensable:
- Animal husbandry,
- Handling of sensitive liquids of various types… including chemicals,
- Water treatment plants,
- Food industry,
- etc.
The acoustic signal can help to prevent overloads or exhaustion situations that could damage the system or cause interruptions in the supply. Alertness and timeliness, activation of safety procedures or warnings are all potential activities thanks to Sentinel and Sentinel 2.
Features
- Effective and Safe Control: The system guarantees timely, efficient, and safe monitoring, providing immediate feedback at affordable costs.
- Prevention from Significant Damages: The use of acoustic signals prevents critical overloads or depletions, thus preserving the integrity of the water storage system and the regular water supply flow.
- Versatile Power Supply: The device can be powered either through the electrical grid or by an internal rechargeable 9V-110mA battery. Additionally, there’s an option to customize the power voltage upon request.
- Sentinel 2 Variant: This variant includes a clean contact output relay, allowing the activation of remote alarm signals for even more comprehensive control.
- Broad Application Possibilities: It finds varied applications in sectors such as pumps, swimming pools, animal husbandry, the food industry, as well as in water treatment and other industrial contexts.
