What people are saying about the ID-200

People love PhoEnix Falls Café, here’s what they’re saying

“The ID-200 stood out for its reliability under high-pressure, high-temperature conditions. It delivered consistently accurate results, even in our most demanding desalter applications.”

M Thompson, Lead Facilities Engineer, United States

“We trialed the ID-200 across several sites, and the repeatability and stability of the readings were unmatched. It’s a rock-solid solution for interface control in critical operations.”

L Cheng, Instrumentation Specialist, China

“The ID-200 has completely transformed our tank dewatering process. We’ve seen a significant reduction in hydrocarbon losses and improved separation accuracy. Installation was straightforward, and it integrated seamlessly with our existing systems.”

C Jiménez, Senior Process Engineer, Spain

“After deploying the ID-200, we were able to reduce chemical usage by nearly 30% thanks to its precise interface detection. It’s a great example of smart instrumentation done right.”

S Moreau, Process Control Engineer, France

“We’ve worked with several interface detectors over the years, but the ID-200 outperforms them all. It’s intuitive, low maintenance, and backed by excellent technical support from PMA.”
