The APG LPU-2127 Level Sensor is a loop-powered ultrasonic level sensor with a range from 1 to 25 feet and Class 1, Div 2 certification. Designed for easy set-up, the LPU-2127 is loop-powered for faster, more efficient wiring and programming is done entirely through the integrated keypad, providing an easy interface eliminating the need for a computer. The sensor is virtually maintenance-free.
The LPU-2127 provides continuous level/distance measurements that are accurate to ±0.25% of detected range. Its durability, range, and simplicity make it a great sensor for many applications. With CSA hazardous location certification, and a durable housing with high chemical compatibility, the LPU-2127 ultrasonic sensor performs well under stress.
This product can be used in the following applications:
The Background: Our customer is an automation company working on a project at a wastewater treatment plant which requires the replacement of an older ultrasonic level sensor.
The Problem: The application is a wet well for a lift station. A pressure sensor inside the wet well is used for primary measurement, with the current ultrasonic level sensor used as secondary confirmation. It’s important to have two readings because overflow/leakage would be a violation of the operating permit for the treatment plant resulting in fines.
The Solution: The customer chose the APG LPU-2127, a US-made ultrasonic level sensor which has the reliability, range and accuracy for the application while offering Class 1, Div 1 certification.
