Meet the LCR.iQ™ and the Team behind it!

Liquid Controls set out to develop a product from the ground up that would change the industry forever, but knew they couldn’t do it alone.

It took nearly two years of close collaboration with industry leaders, customers, and end users to develop what is now considered the new benchmark in electronic meter registration.  The result is the CENTRILOGiQ® connected technology platform and the LCR.iQ®: the most powerful and scale-able electronic register platform ever produced. It features a bright high-definition display for easy visibility, durable construction to withstand the elements, large configurable smart keys, and requires little to no training to operate.  Further, the LCR.iQ® was awarded the 2019 iF Design Award by the International Design Federation its user-friendly design and demonstrated intelligent features in the Discipline of Product, Industry & Tools category.

Designed with the future in mind, the LCR.iQ® introduces new potential to OEMs and end users to fully customize the fueling experience with configurable screens and tickets, adaptable software, real-time on-screen diagnostics, and remote data access with controls via embedded Wifi and Bluetooth -- opening the door to near-infinite platform expand-ability. 

We’re excited to empower our customers with a revolutionary user experience and the limitless possibilities of the LCR.iQ®.
