RadioSecure™ WLS is an integration of the precision ultrasonic level sensor technology with Envotech’s Trademark RadioSecure™ container tracking and monitoring devices.
The RadioSecure™ WLS is a family member of the RadioSecure™ range of products with wireless connectivity to the RS IVM (In Vehicle Monitor) or RS SLM (Seal Locked Master). RadioSecure™ WLS periodically reports fuel status wirelessly to the RS SLM or RS IVM which will report via GSM infrastructure to a hosted web base supply chain security and visibility.
This level sensor continuously detects the height of the liquid level in the tank with less than 1mm resolution.
Ultrasonic sensor is capable of measuring up to a maximum of 2000mm deep with high precision. Continuity on both sophisticated technology produced a successfully trending product.
The reporting frequency is also user programmable. This innovative real-time wireless level-monitoring solution works for all fuel monitoring applications.
