The APG IRU-2000 Level Sensor is an ultrasonic level detector designed for detecting solids and moving objects. Built to mount on walls, ceilings, and other flat surfaces, IRU-2000 transducers are often used for presence/absence detection, object profiling, and more.

The APG IRU-2000 has a range from 1 to 25 feet with liquids and 1 to 10 feet for solids. The sensor has a basic accuracy of ±0.25% of detected range. These ultrasonic sensors are built for use outside of the tank environment. Instead of a threaded fitting, they simply bolt onto a flat surface.

The IRU-2000 level sensors are designed for a variety of applications, and therefore have ample programming options to accommodate many needs. A number of output options are available such as a solid state relay, isolated 4-20mA, RS-485 with 1 NPN trip point, or 4-20mA with 2 NPN trip points.
