American Innovations Introduces its New Bullhorn® RM4151 Remote Monitor for Cathodic Protection Rectifiers

American Innovations (AI), protecting people and the environment with compliance solutions for the oil and gas industry, introduces its new Bullhorn® RM4151 remote monitor for cathodic protection rectifiers.

Built on the same platform as our award-winning five-channel Bullhorn® RM4150, the RM4151 is a two-channel version that remotely monitors volt and amp measurements—with a 1 percent reading accuracy—from CP rectifiers. The remote monitor then sends this data, via a GSM cellular network, to AI's Web interface, Bullhorn Asset Tracker (BAT™). Having this data at their fingertips enables users to more quickly and efficiently evaluate, maintain and repair their cathodic protection systems.

Other Bullhorn RM4151 features include:

  • Two analog channels that can measure a voltage as DC or AC
  • Worldwide GSM cellular communications for compatibility with 2G/3G/HSPA/4G networks around the globe
  • GPS-synchronized Interruption for close interval, depolarization and DCVG surveys
  • Interference mode for influence studies
  • Quick and easy installation
  • "Built Bullhorn Tough," enabling it to withstand extreme working conditions

"The performance and price of the RM4151 make it ideal for our oil and gas customers with basic rectifier monitoring requirements," says AI President Ed Kruft. "This basic monitor complements our Bullhorn RM4150, intended for customers needing more complex measurement capabilities."
