Using Differential Pressure to Measure Liquid Level When Density Changes

12. January
A pair of VEGABAR 80 series pressure sensors in an electronic differential pressure (EDP) configuration mounted to the side of a froth flotation cell.
In the third and final installment of our blog miniseries on monitoring the pressure of liquids with changing densities, pressure product manager Jeff Brand explains how to make a consistent density-compensated level measurement with an electronic differential pressure system.

Calculating Density with Differential Pressure

Interview: Darrell Fairbanks

08. December 2017
Field Service Technician and trainer extraordinaire Darrell Fairbanks has spent 35 years working in industrial instrumentation, the last 17 years with VEGA Americas. In this interview, hear what makes end users excited about the VEGAPULS 64 liquid level radar sensor and what makes Darrell excited to come to work every morning.

VEGAPULS 64 level sensor monitors active ingredient concentration in pharmaceuticals

08. December 2017
The dual requirements for instrumentation used in drug manufacturing demand both perfect hygiene and maximum precision: even the smallest accuracy deviations in a process can lead to large differences in the potency of the medicine. A pharmaceutical company near Shanghai uses extraction processes to produce biological drugs with highly precise dosages of active ingredients.

Ball Valves, Gate Valves, and 80 GHz Radar: What We've Learned

01. December 2017
Isolation valves are common in many automated processes, especially those involving harsh liquid products. Isolating a level measurement sensor from a volatile product protects plant personnel and the sensor. Historically, using a through-air radar sensor in such an application has proven problematic. After hearing about successful and reliable level measurement using 80 GHz radar on isolation valves in the field, we tested the VEGAPULS 64 on valves in our lab. Find out what we learned.
