Sierra's Vortex flowmeter provides readings of five critical process variables from a single pipeline entry point. It measures the fluid's velocity, temperature and pressure and calculates mass flow rate, volumetric flow rate and density. All of these variables are displayed by the meter and any three can be transmitted by means of 4-20 mA outputs.
The Vortex meter is good for steam but also suitable for most gas and liquid applications. Most frequent uses are for steam generation and distribution management and measurement of actual energy flow into and out of processes. These meters can be used in lines from 25 to 1800 mm.Typical accuracies are 1,5% of mass flow rate over 30:1 turndown range.

Editor's Choice Flow Measurement & Control
There are many processes where it is undesirable for the load to suddenly change quickly, for example in the paper industry. Examples of level control have involved reasonably fast tuning. An example of a level loop tuned this way and responding to a step change in setpoint is given.

Editor's Choice Flow Measurement & Control
It is very important that reboiler temperature controls operate well in petrochemical refineries, or the product quality can really suffer. I was asked to check such a control in a refinery where they were having problems with one of these controls.
