Name: Escort ALS
Brand: Escort Sensors

Escort ALS Main Advantages

The measuring part can be extended up to 295 cm

Interfaces perfectly with monitoring systems of any manufacturer

Combines the most common types of output signals: digital RS-485, frequency, and analog

It is possible to measure the level of a conductive liquid in various containers

The water level sensor is configured, connected, and installed similarly to the fuel sensor Escort

It is ideal for factories that use water or process fluids, utilities, irrigation systems, and rice paddies.

Escort ALS Wireless BLE Level Sensor for Precise Liquid Monitoring & Telematics Integration

Discover the Escort ALS, a cutting-edge wireless level sensor from Escort Monitoring Systems designed for precise monitoring of liquid levels in storage tanks across industries like agriculture, oil and gas, and water management. Engineered with Bluetooth Low Energy (BLE) technology, this device eliminates complex wiring, simplifies installation, and delivers real-time data with up to 1% measurement accuracy, ensuring reliable detection of conductive liquids, including water, weak alkali solutions, and technical liquids.

Compatible with popular GPS/GLONASS trackers such as Teltonika, Geotab, Ruptela, Navtelecom, Galileosky, and others or via a BA BLE BASE adapter for RS-485 interfaces, Escort ALS enhances fuel theft prevention, inventory tracking, and operational efficiency.
