Milesight

Zone leak detection sensor

Milesight EM300-ZLD-868M is a zonal LoRaWAN leak sensor designed for monitoring larger areas at risk of flooding. The detection cable with a standard length of 3 m detects the presence of conductive liquid, enabling protection of applications including pipelines, server rooms, technical rooms, and raised floors.

The device also measures temperature from −30 to +70°C and humidity from 0–100% RH. The IP67 enclosure, local storage for 2800 records, data retransmission, Milesight D2D, and a replaceable 4000 mAh battery enable long-term and independent infrastructure monitoring.

EM300-ZLD — Leak Monitoring Along the Entire Protected Zone

Milesight EM300-ZLD is a wireless sensor designed to detect the presence of water and other conductive liquids across a larger installation area.

Instead of a single measurement point, the device uses a detection cable with a standard length of 3 metres. It can be routed along a pipeline, beneath equipment, or around protected infrastructure to detect a leak regardless of where it appears along the cable route.

Protect a Larger Area with a Single Sensor

3 m Cable

The sensor detects liquid along the detection cable, allowing it to protect a larger zone than a conventional point detector.

Temperature and Humidity

Built-in environmental sensors simultaneously monitor temperature and humidity at the installation location.

Alarm via LoRaWAN

Information about detected liquid can be automatically transmitted to the supervisory system and used for immediate alarming.

Where Can the EM300-ZLD Be Used?

Pipelines and Water Installations
Server Rooms and Data Centres
Raised Floors
Technical Rooms
Pumping Stations and Pumps
Basements and Garages
Technical Cabinets and Equipment
Warehouses

One Cable Can Protect the Entire Installation Route

The EM300-ZLD is particularly suitable where the exact location of a potential leak is difficult to predict. The cable can be routed along a water installation, near equipment, or across the floor of the protected room.

Contact between conductive liquid and the cable generates an event that can be transmitted via LoRaWAN to the monitoring system.

Local Response Without Waiting for the Cloud System

The EM300-ZLD supports Milesight D2D, allowing an event to be transmitted directly to a compatible Milesight device without using a LoRaWAN gateway or server.

This makes it possible to use leak detection to quickly activate a local alarm, relay, valve, or another automation component.

2800 Records and Data Retransmission

2800 Records

The device can locally store up to 2800 historical records.

Retransmission

Data stored during temporary communication loss can be retransmitted after the connection to the LoRaWAN network is restored.

Data Recovery

The Data Retrievability function enables historical data stored directly in the device memory to be retrieved.

IP67 Enclosure and Resistance to Outdoor Conditions

IP67

The sealed enclosure protects the electronics against water and dust during operation in demanding conditions.

UV Resistance

The device design is also suitable for applications exposed to UV radiation.

Flexible Mounting

The module and cable can be mounted in a manner adapted to the installation route and protected area.
