New Applications for Pressure Measurement Technologies

Accurately measuring liquid, gas, and steam pressure is a basic requirement for many industrial processes to operate safely, efficiently, and with optimum quality control. In addition to directly measuring pressure values, pressure measurements can be used to determine or infer flow rates, fluid levels, product density, and other parameters. As a result, many plants rely […]

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 […]

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 […]

What are the Strengths and Weaknesses of Differential Pressure Flow Devices?

There have been whole books written about differential pressure (DP) flow devices (orifices, pitot tubes, flow nozzles, venturi meters, elbow taps, wedge meters, averaging pitot, etc.) I only have space to hit the highlights and suggest that you pick up any of several books on the subject if you want to know more about this […]
