EM400-UDL Ultrasonic Level Sensor

EM400-UDL Ultrasonic Level Sensor

The Milesight EM400-UDL is a professional non-contact ultrasonic distance and liquid level measurement sensor designed for demanding industrial applications. With high accuracy, wide detection range, and multiple connectivity options (LoRaWAN, NB-IoT, Cat-M), it delivers reliable data for water management, tank monitoring, wastewater treatment, and smart city projects.

Key features

• Non-contact measurement: Ultrasonic technology measures liquid, dust, or solid surfaces without contamination
• Multiple connectivity options: LoRaWAN (2 km urban, 15 km rural range), NB-IoT, and Cat-M versions
• Extended battery life: Up to 10 years of operation
• Rugged design: IP67 rating, suitable for industrial environments
• Additional monitoring: Built-in 3-axis accelerometer for device tilt status tracking
• Temperature monitoring: NTC thermistor for ambient temperature measurement and sharp change alerts
• Standard and Pro versions: Five probe options for flexibility
• GNSS positioning: GPS module support in NB-IoT version

Benefits

• High accuracy: Non-contact measurement prevents contamination of the measurement element
• Flexibility: Standard and Pro versions with different detection ranges and resolutions meet diverse requirements
• Lower operating costs: Extended battery life and efficient data transmission reduce maintenance expenses
• Wide coverage: LoRaWAN provides reliable signal in urban and rural areas
• Fast alerting: Immediate notifications on temperature and tilt changes
• Easy integration: Compatible with standard IoT protocols and existing systems

Use cases

• Water and wastewater management (tank, pool, settling basin level monitoring)
• Industrial liquid storage (chemical, food, petroleum)
• Smart city infrastructure (rainwater, drainage system monitoring)
• Agriculture and irrigation (water source and reservoir management)
• Environmental monitoring (river, lake level tracking)

Technical notes

• LoRaWAN Version: 2 km urban, 15 km rural range; low power consumption; private and public network options
• NB-IoT & Cat-M Versions: Reliable transmission via cellular base stations; GNSS positioning; data packet accumulation up to 24 per report (transmission and power savings)
• Cellular Bands: Cat-M1: B1/B2/B3/B4/B5/B8/B12/B13/B18/B19/B20/B25/B26/B27/B28/B66/B85; Cat-NB2: B1/B2/B3/B4/B5/B8/B12/B13/B18/B19/B20/B25/B28/B66/B71/B85
• Protection class: IP67 (dust and water resistant)

Version differences

The EM400-UDL is available in two main versions:

• Standard Version: Standard detection range and resolution for basic applications
• Pro Version: Extended detection range and high resolution for projects requiring precise measurement

Each version can be configured with LoRaWAN, NB-IoT, or Cat-M connectivity. Five different probe types (including Standard and Pro probes) enable adaptation to various environmental conditions.
