Ultrasonic Level Sensor Included
The OleumTech® OTC Wireless Ultrasonic Transmitter does not come in contact with the liquid (product) or have any moving parts that require maintenance. Specifically designed for water and wastewater applications, the WT-LL6 can measure up to 12 ft of water level with a high resolution of 0.04 inches. The WT-LL6 can be installed easily and quickly with the provided mounting hardware. Additional data such as volume and tank full percentage can be reported as well based on user preference. This ultra-low-power transmitter is powered by a replaceable battery pack that provides up to a 10-year life.1 The push button LCD interface allows for device configuration and instant access to process data.
Reliable, Scalable and Safe
The field-proven wireless transmitter communicates with an assigned wireless gateway within the OTC Wireless Sensor and I/O Network creating a highly scalable network, accommodating virtually any I/O requirement.
The OleumTech wireless transmitter is designed for general purpose applications
