Enigma5-BB: Advanced Leak Detection for Enhanced Network Coverage

COMPACT, LIGHT WEIGHT AND MAINTAINABLE

The Enigma5-BB can be securely installed on the pavement near customer meters, avoiding hazardous roadwork. Its lightweight, compact, and durable design makes it easy to handle and install, while maintaining the robustness required for harsh environments. With a secure locking mechanism that attaches to boundary boxes and can only be removed using an Ovarro key, it minimizes the risk of unauthorized removal. These features, along with an IP68 rating, make the Enigma5-BB a versatile and efficient solution for water companies aiming to enhance leak detection and operational efficiency.

DISCOVER THE BENEFITS OF THE ENIGMA5-BB

The Ovarro Enigma5-BB offers an innovative design, building on the Enigma3hyQ with increased leak detection capabilities along with:

A hydrophone that does not need hydrant fitting:

Reduced risk of asset damage
No leakage due to frost plug
Can be fitted to existing boundary boxes

A flexible logger placement:

Utilise current infrastructure for placement
No impact to customer metering
Enables shorter distance between sensors

Increased operational efficiency:

No flushing operation needed
Improved communication up-time

NO LEAKAGE DUE TO FROST PLUG

The hydrophone is not reliant on a hydrant fitting, reducing the risk of asset damage and ensuring no leakage due to the use of a frost plug. Teams are also able to fit the Ovarro Enigma5-BB to existing boundary boxes, increasing operational efficiency.

FLEXIBLE LOGGER PLACEMENT

The flexible logger placement enables longer distances between sensors, allowing in-field leakage teams to utilise current infrastructure with no impact to customer metering.

This means that unlike hydrants and wash outs, the Ovarro Enigma5-BB can be fitted on the pavement where the customer meter is located, avoiding potentially dangerous work on the road.

Enigma5-BB is locked onto the boundary box only to be removed by an Ovarro key, and cannot be removed by any routine methods.

The new Enigma5-BB features Bluetooth for quick setup via the Enigma5 app, eliminating the need for a communications module. Advanced MQTT security ensures reliable, encrypted data transmission and seamless integration.
