Nautic Alert Nevata

The Problem

When a bilge high water alarm sounds something has failed, and the yacht is now sinking.

According to BoatU.S. April 2014, “more than two-thirds of the reasons why boats sank could be considered preventable” and “69% of the boats that sank did so at the dock or while moored.”  

The Solution

NEVATA – a SMART wireless sensor designed to control bilge pumps based on learning the characteristics of the pumps and understanding what is normal based on water level measurements obtained through sound waves and predictive analytics to identify the beginnings of a problem.

How effective is Nevata?  As effective as detecting pin-size leaks and unexpected water entry due to potentially severe and life-threatening issues.

Predicitve Analytics

NEVATA continuously captures pump operating data, electrical data, water level data and test data while continuous performing analysis to detect events leading to a potential problem.  Information is provided to Nautic Alert Insight X2 for deeper analysis of all onboard Nevata sensor data. Reports and graphs available to an owner through My Insights portal.

Pump Cycle Stats

Nautic Alert compares cycle data from each controller, which is useful for spotting irregular patterns as shown in the diagram.

Use Case:  Customer received notification due to 6 month old Rule 2000 pump experiencing an air-lock issue, where pump would not remove standing water.

Nevata Daily Runtime

Nautic Alert shows total runtime and cycles of each Nevata, stationary vs while underway.

Use Case:  Useful for monitoring 3rd party systems such as Arid Bilge system, which was operating much more than usual as visually seen in the graph. In this case, the customer experienced an air lock issue due to an impeller jam, and was notified.

Pump Average Current Draw

Useful for predicting bilge pump end-of-life as pump current starts to rise over time.

Use Case:  Customer receives notification of irregular bilge pump behavior and proactively replaces the bilge pump with a new one, thus avoiding a pump failure situation.

Nevata Average Cycle Time

Useful for predicting hardware degradation issues over time, such as a developing blockage or impeller/pump loosing effectiveness

Nevata Cycle Log

Useful for seeing bilge pump cycling details and bilge compartment temperature by location.

BACKWARDS COMPATIBLE

Replace or keep the float and existing override switches as a backup. With Nevata 200 series, it will detect when an external source is driving the pump and keep the pump’s runtime seconds in-sync.

INNOVATIVE

The traditional bilge pump switch has been reivented, introducing the patented Nautic Alert Nevata, the marine industry’s leading Bilge Pump Switch and Controller that is intelligent and makes decisions.

SMART

Learns the attached bilge pump characteristics in combination with or without water level measurements to control the pump activation and deactivation and to make evidence-based decisions.

SIMPLE

Single button to auto calibrate Nevata, auto set the pump activation level, and auto set the water alert level based on the measured bilge compartment depth.  Activate auto configuration from Nevata or from Nautic Alert Insight.

PRECISE

Nautic Alert Nevata uses sound waves to measure water level in a bilge compartment from above the waterline and knows exactly how much water is in your bilge, at all times, down to 1/10th of an inch.

RELIABLE

Integrated pump counter, manual override switch, and bilge high level alarm into a single housing, best of all, it is waterproof and designed with no mechanical parts and a solid-state marine grade design for reliability.

WIRELESS

No need to pull data cables because Nautic Alert Nevata and Nautic Alert Insight use the 2-Way Nautic Alert Wireless Sync network to talk to each other.  Communication is encrypted for secured communication.

Multi-Fault Assessment

A bilge pump system is critical to dealing with the removal of unwanted water in the bilge compartment; however, there are times unexpected events occur such as a bilge pump not being able to siphon water because of an ingress blockage, failed bilge pump, or a through-hull fitting starting to fail causing the bilge pump to run continuously or to exceed its capacity. Nautic Alert Nevata™ monitors for bilge pump system events using its Multi-Fault Assessment technology. When an event is detected, Nevata will make evidence-based decisions such as activating the bilge pump or auto swapping to a backup pump to determine if this resolves an event while issuing a notification.

With Fault Recovery capability, Nevata can determine the presence of water in the bilge compartment even without a water level measurement because of its learning capability and its intelligent decision making ability designed to find the proper corrective action for event resolution and event notification.

Multi-Fault Assessment Capabilities

    • Bilge Pump Failure Detection
    • Bilge Pump Runtime Monitoring
    • System Trouble Detection
    • Water Sensor Interference Detection
    • High Water Level Detection
    • Nevata Health Reporting
    • Fault Recovery and Notification

Pump Swapping Capability

If the rate of incoming water is too much for a small primary pump to handle or the primary pump is in a failed status, Nautic Alert Nevata will automatically switch to a larger capacity backup pump. Note: Requires Nautic Alert Dual Pump model.


Bilge Compartment Temperature

Knowing the temperature in your bilge compartment is a Nevata capability so you remain aware of the risk when keeping your yacht in cold waters or operating in a cold weather environment.  Nevata has you covered with customizable pre-freeze and freeze alerts and continuous temperature monitoring.
* Requires Nautic Alert Insight.
