Description

The Milesight EM500-UDL is a carrier-grade LoRaWAN Ultrasonic Level Sensor engineered for versatile distance measurement without physical contact. By emitting ultrasonic waves and measuring the time of flight, the EM500-UDL accurately determines the level of liquids or the presence of solid objects. Housed in a rugged IP67-rated enclosure, it is purpose-built for outdoor applications where reliability and longevity are paramount, such as flood monitoring, tank level tracking, and waste management.

Non-Contact Intelligence & Reliability

Advanced Signal Processing Features integrated temperature compensation to ensure measurement accuracy remains consistent despite fluctuations in ambient weather conditions.

Data Integrity & Retransmission Equipped with internal memory to store historical records, supporting data retransmission to prevent gaps in analytics during temporary LoRaWAN network outages.

Professional Usage Scenarios

• Flood & River Monitoring: Deploy on bridges or culverts to track rising water levels and provide early warnings for disaster prevention.

• Smart Waste Management: Monitor the fill-level of waste containers or grain silos to optimize collection routes and supply chain logistics.

• Liquid Tank Monitoring: Ideal for non-potable water, chemicals, or oils where non-contact sensing is required to maintain purity or sensor life.

Measurement Technology
- Non-Contact Ultrasonic Sensing: Utilizes ultrasonic waves to detect object distance or liquid levels without physical contact, preventing sensor fouling or corrosion.
- Milesight D2D Support: Features the D2D communication protocol for ultra-low latency direct control between sensors and controllers without a gateway.
- Industrial Endurance: Engineered with an IP67-rated UV-resistant enclosure to ensure long-term stability in harsh outdoor and industrial environments.
- Data Continuity: Supports local storage of historical records and automated retransmission to protect against data loss during network outages.
- Ultra-Low Power Consumption: Optimized hardware design allows for a maintenance-free service life of up to 10 years on a single battery.
Measurement Range
- Dual Version Options: Available in a standard version (0.3m to 5m) and a long-range version (0.5m to 10m) to suit varying application heights.
- Wide-Area Detection: Effectively monitors large-scale structures such as water tanks, silos, and open pits.
- Blind Zone Management: Optimized for minimal blind spots (30cm or 50cm depending on model) to maximize usable measurement volume.
Measurement Accuracy
- Industrial Precision: Delivers high-fidelity measurements with an accuracy of ±1% Full Scale (FS).
- Automatic Compensation: Sophisticated algorithms compensate for environmental variables to ensure consistent readings across the -30°C to +70°C temperature range.
- Signal Reliability: High receiver sensitivity (-137dBm) ensures reliable data packets even in complex signal environments.
Measurement Resolution
- Millimeter Precision: Provides a high measurement resolution of 1 mm, essential for accurate volume calculations in tanks and containers.
- Intelligent Filtering: Built-in signal processing filters out noise and transient reflections for stabilized reporting.
- Reporting Flexibility: Transmission intervals are fully configurable via NFC to align data granularity with specific project requirements.
