How to Improve Industrial Productivity with Loop Calibration

The typical approach to calibration has been to regularly test instrumentation that affects successful control, safe operation, quality, or other relevant criteria. In most cases, scheduling is conservative, and methods at a particular site have evolved over time. Instrument technicians follow practices that were set up many years ago. It is not uncommon to hear, […]

Webinar Recording: How to Calibrate Differential Pressure Flowmeters

In this webinar, experts examine the complexity of testing popular multivariable differential pressure cells that provide a compensated flowmeter output based on differential inches of water (inH2O), static (psia) and temperature (RTD) variables. While this smart instrument can make a very accurate measurement, it is often a “mystery” as to how to properly check and […]

Webinar Recording: How Does Low Flow Affect Differential Pressure Flowmeter Calibration?

For flowmeter calibration, the phenomenon of “low flow cut-off” is only associated with differential pressure transmitters with square root extraction—if the square root (flow) calculation is done in the control system (DCS/PLC), then this test approach does not apply. The graphic below illustrates the issue. Some may ask why we are testing the initial point […]

How to Build an Industrial Calibration System Business Case

An investment into calibration equipment and systems must be financially justified, just like any other business investment. But does a cheaper cost of purchase always mean a higher return on investment? Not necessarily. When building a business case for calibration system investment, what may seem at the outset to be cheaper may not necessarily be […]

Vibration Sensor Monitoring and Calibration Protects Vital Plant Machinery

Seismic velocity measurements provide ideal resolution at typical rotating equipment running speeds. Vibration is always transmitted through the bearings used on rotating equipment. It has been proven time and time again that measuring vibration on rotating equipment is the most universally effective predictive maintenance practice for critical pumps, motors, compressors, fans, cooling towers and rollers. […]

Webinar Recording: How to Avoid the Pitfalls of Implementing a Calibration Process Change

After you have made the decision to get out of your calibration rut, the next step is to outline a system implementation process. Remember that implementing a fully integrated, automated calibration solution is a process. It simply won’t happen overnight, and needs to be done in steps. Before talking about the steps, let’s review a […]

A Closer Look at Process Instrument Commissioning

Process instrument commissioning is an essential part of an overall plant’s commissioning program and is necessary for ideal plant performance. It requires an allocated budget, time, and trained personnel, and must be considered within the scope of the overall program. Typically the most common activities that affect time and cost in a conventional process instrument […]
