American Innovations’ Bullhorn RM4150 for Accurate Remote Monitoring of Cathodic Protection Assets

American Innovations, protecting people and the environment with compliance solutions for the oil & gas industry, has released the Bullhorn RM4150 for accurate remote monitoring of cathodic protection (CP) assets. By collecting and communicating rectifier measurements using GSM networks, operators can meet 49 CFR 192/ 195 regulations and protect their pipelines.

Bullhorn RM4150 for CP Monitoring

The RM4150 RMU was created to monitor rectifiers used in cathodic protection systems. It has five analog channels and two digital channels to monitor rectifiers on pipelines, well casings, tanks and other assets. The unit measures AC & DC volts and amps, pipe-to-soil potential, shunts, Instant Off, line power presence and more – all with 1% of reading accuracy. This allows high resolution changes to be observed and monitored, and allows the measurement of very low mV readings to accommodate current shunt measurements. Operators typically no longer need to change a shunt to adapt to limitations of measurement devices.

The digital channels provide an accumulator for metering applications and, with an optional accessory, intrusion detection. It includes GPS-synchronized interruption for close interval, depolarization, and DCVG surveys.

The RM4150 installs quickly and is easy to set-up. It is small enough to fit inside most rectifiers or mounts externally using an optional NEMA 4X enclosure. It features over-the-air configuration and firmware upgrades via the Bullhorn Asset Tracker (BAT™) website. The RM4150 also communicates measurement readings to AI’s Pipeline Compliance System (PCS™) via BAT to give operators the ability to further manage, analyze and report on data collected in the field.

“The RM4150 was designed using feedback and requirements from our oil & gas customers who needed an accurate, easy-to-install CP rectifier monitoring product with interruption. The technology expands on our successful line of satellite communication RMUs, and provides customers with a single monitoring solution that works well in both remote and urban areas,” said Jaco Botes, Director of Product Strategy. “Because the unit has built-in interruption with interference mode, operators can efficiently run rectifier influence studies and close interval, depolarization and DCVG surveys.”

Remotely collecting accurate rectifier measurements and more is a cost-effective way for pipeline companies to optimize the life of their CP assets and meet regulatory requirements. For pricing and availability, please contact Sales [email protected]
