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 […]

The Good, Bad and Ugly of Thermal Mass Flowmeters

Thermal mass flowmeters can be a relatively inexpensive flowmeter that can handle extremely small flows (e.g., inline 1/16-inch meters) and large flows (e.g., multipoint insertion type in 60 inch ducts). Thermal flowmeters introduce heat into the flow stream and measure how much heat is absorbed using one or more temperature sensors. However, the meter requires […]

ISA Technical Education and Training for September and October

In September, drill down on process control with ISA’s Process Automation Boot Camp. Designed for non-maintenance personnel with little or no background in process measurements and control, this hands-on course focuses on the physical measurement technologies, the communication signals, and various applications of instrument equipment to achieve common process measurements and control. An exciting mix […]

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

    This post has been updated with the webinar recording. 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 […]

PID Tuning for Near and True Integrating Processes

The most important loops on vessels and columns typically have a near or true integrating response. A self-regulating process is classified as near integrating if the process time constant is larger than four times the process dead time. The composition, pH, and temperature response of continuous columns tend to have a time constant to dead […]
