Density delivers in-process analysis

Level, flow and density instrumentation offer cost-effective ways to assess process fluids.

In-situ density measurements have long been useful in process control applications from recycling nuclear fuel and refining oil to measuring beverage proof or degrees Brix (°Bx) sugar content of an aqueous solution. Density measurements can provide real-time determinations of concentration, blending ratio, fermentation, or oil API (American Petroleum Institute) gravity, which measures oil heaviness or lightness, etc. These can be used to adjust process variables and optimize throughput, quality, equipment and material utilization, and energy efficiency. So it’s no surprise that densities of liquids, slurries and mixtures in vessels and pipes have been measured for…

Voices: Ask The Experts

Ask the experts: Level switch safety; level for flow

Are piezoelectric switches really safe in hazardous areas? How can we use a level gauge to set a flow alarm?

Q: Are piezoelectric switches really safe in hazardous areas? I understand that in the vibrating, tuning fork-type level switch, a piezoelectric crystal is generating an oscillating frequency. We have a Class A product stored in a tank, which requires a Zone 0 installation, and I need a level…
