Non-Contact Liquid Level Sensor LoRaWAN – Milesight EM300-CL-868M

The Milesight EM300-CL-868M is a capacitive, non-contact liquid level sensor designed for monitoring liquid levels in non-metallic containers.

The sensor is mounted externally on the container and measures the liquid level through the container wall. The electrode pad does not enter the liquid and does not come into contact with the medium. This ensures hygienic operation, easy maintenance and zero contamination risk.

Using a capacitive detection principle, the device triggers an alarm when the liquid level reaches or drops below a defined threshold.

Compatible container materials:

Plastic

Glass

Acrylic

Typical applications:

Soap and sanitizer dispensers

Cleaning chemical containers

Hygiene stations

Facility management systems

Smart washroom monitoring

LoRaWAN® (EU868) enables long-range wireless communication with ultra-low power consumption. The integrated 4000 mAh battery supports over 10 years of operation under typical usage conditions.

Configuration is performed via NFC using a mobile app. The transceiver is IP67-rated for reliable operation in demanding environments.

Important:
The EM300-CL measures only through the container wall. No probe is inserted into the liquid.
