Milesight EM400 Multifunctional Ultrasonic Distance/Level Sensor

Product Description

The Milesight EM400 Multifunctional Ultrasonic Distance/Level Sensor is a robust, non-contact measurement device engineered for reliable level monitoring of liquids or solid waste in large containers, silos, and open bodies of water. Utilising ultrasonic technology, the EM400 accurately measures the distance to the surface, providing critical data for efficient resource and logistics management.

Leveraging the energy-efficient LoRaWAN® protocol, the EM400 ensures reliable, long-range wireless data transmission, which is perfect for deployment in remote or challenging outdoor areas like waste depots, water treatment facilities, and agricultural sites. Its design prioritises extreme durability, featuring an IP67-rated enclosure that guarantees protection against heavy rain, dust, and harsh weather conditions.

The EM400 offers high versatility, capable of monitoring distance and, critically, translating that into a calculated level or fill percentage. Its non-contact operation prevents sensor contamination and wear, making it perfectly suited for monitoring corrosive liquids or unsorted waste materials.

The EM400 finds ideal use in many areas, such as:

• Smart Waste Management (Monitoring refuse skip and bin fill-levels)
• Water Management (Measuring water levels in rivers, tanks, or reservoirs)
• Logistics and Storage (Silo and bulk material level monitoring)
• Facility Management (Measuring lubricant or chemical levels in industrial tanks)
• Agriculture (Irrigation water monitoring)

This smart device transmits measured distance and calculated level data to a connected LoRaWAN® gateway. The data is then forwarded to your chosen third-party platform for monitoring, alarming (e.g., high-level warnings), and trend analysis by a LoRaWAN® network server.
