A Georgia-based provider of natural gas measurement and control products and solutions has announced the acquisition of a distribution and service center for the natural gas industry, extending its capabilities for heat treating manufacturers.

Equipment Controls Company‘s acquisition of Tri-State Meter and Regulator Service, Inc. is expected to expand geographic reach and operational capabilities of both companies and merge field services, installation and testing, fabrication and design, and leak surveys.

“We’re excited to welcome the Tri-State team to Equipment Controls,” said Jeb Bell, president of Equipment Controls Company. “Tri-State has built its reputation on a foundation of exceptional service. Their motto, ‘The Service Matters,’ resonates with our values, and we’re eager to extend that level of service to our customers.”

“We look forward to our future with ECCO. Our shared vision and complementary strengths will enable us to deliver exceptional value to our customers and the natural gas industry as a whole,” said Paul Hayes, president of Tri-State Meter and Regulator Service, Inc.

ECCO will be keeping Tri-State’s brand, team, offices, products, and service offerings.

Reader Feedback: On SATs, Correction Factors, & Possible Findings

On Jason Schulze’s article, “Understanding AMS2750E—Standard SAT Description” (click here to see original article):

READER QUESTION: Just read your article in regards to system accuracy test. I just had a question that maybe you can help me understand. When applying the correction factor of the test instrument and test sensor, is the correction factor to be used based on the furnace set point (operating temperature) at the time of the test or the recording instrument reading during the test? Any insight is appreciated!

This is a question that comes up often in the pyrometry courses I teach.

The Nadcap Pyrometry Reference Guide, question #6, addresses this question, although from a TUS standpoint. The premise is the same for the SAT process though.

Correction factors applied to any test results (TUS & SAT) should be determined based on the setpoint temperature during testing.

One thing to remember is that you may be testing at a temperature which does not fall directly at a temperature indicated on the test wire/test instrument calibration certificate. In this case, you would have two options;
1) Linear Interpolation
2) Pick the adjacent calibration temperature closest to your setpoint during test.

Either way, you would need to establish if you execute #1 or #2 above and document that in an internal procedure.

READER QUESTION: Thanks for the feedback, I have another concern. I perform an SAT on a refrigeration unit that operates at -20 degrees. My test instrument and test sensor are both calibrated at a low temperature of -20, but sometimes the recording instrument indicates a temp of -21 degrees or so. My operating temperature is -20 (setpoint), but as I stated it might indicate a lower temperature. Is there a possible finding here? Although setpoint is -20, recorder shows -21, which the test instrument/sensor does not cover (calibration point).

Jason Schulze for HTT:

You should be in no danger of a finding. The pyrometry guide states the correction factors are based on setpoint.
