In a major city on the east coast of Canada, Everest Automation, a proud ABB channel partner, successfully sold and commissioned the ABB LLT100 Laser Level Transmitter at a wastewater pumping station. This installation marks a significant upgrade for a facility that had been using an ultrasonic level measuring system for over two decades.
The wastewater pumping station faced substantial challenges due to its aging infrastructure. During heavy rainfall, the existing ultrasonic level transmitter, mounted on the wet well ceiling, often became flooded, rendering it incapable of accurate readings. This malfunction hindered the pumps’ operation, causing the water level to rise dangerously within the narrow entrance ladder way.
After a thorough evaluation of various level measuring technologies, the customer chose the ABB LLT100 Laser Level Transmitter. The decision was driven by two key factors: the narrow entry pathway and the ease of installation. Unlike other solutions, the ABB LLT100 did not require additional equipment like a remote transmitter, making it a straightforward and efficient choice.
The ABB LLT100 was installed at the top of the opening, addressing confined space entry issues. When the ultrasonic transmitter floods, it triggers a fail alarm, prompting the PLC to switch to the laser unit’s analog input. This seamless transition ensures continuous and accurate level readings, even during excessive rainfall. Once levels normalize, the system reverts to the ultrasonic unit.
The installation process was remarkably swift and efficient. Using analog Teck cable, the unit was connected directly to the control panel, eliminating the need for extensive conduit and transducer cabling. The ABB LLT100 requires no echo mapping and is virtually maintenance-free, with no on-site calibration necessary. These features provided a hassle-free solution that significantly enhanced the facility’s operational reliability.
The ABB LLT100 Laser Level Transmitter proved to be a simple, reliable, and easy-to-install non-contact level measurement solution for the challenging environment of the wastewater pumping station. The customer was highly satisfied with the results, leading to the installation of two additional units across the facility.
Everest Automation’s prompt delivery from their inventory and exceptional after-sales support further cemented the success of this project. Partnering with ABB and Everest Automation ensures a winning combination for reliable and efficient process control solutions.
