How to Measure Temperature with a High Density Ethernet IO Solution

Along with monitoring points for pressure, level, and flow, a chemical manufacturer has up to 500 temperature measurement points; both thermocouple and RTD, scattered throughout their process.

V-Cone® for LNG: Safety and Quality Benefits in Cryogenic Processes

The V-Cone is often implemented in upstream, midstream, and even downstream oil and gas processes to measure a variety of flow media in various states and temperatures. The V-Cone’s options for customization are among the many factors that prompt customers to choose this meter for such diverse and varied applications.

Steam & Water Flow Measurement: Going with the Flow

Given the need for accuracy, consistency and repeatability, brewers should always choose the highest quality meter they can afford. Flow metering is all about optimizing production to give the brewer consistent and reliable results through understanding the precise temperatures, pressures and flow being used.

V-Cone Differential-Pressure Meters: Accuracy To Go With The Flow

When space is tight and straight-run piping is at a premium, V-Cone® differential pressure meters are an excellent choice — especially where the potential for turbulence raises metering accuracy issues. This article describes how to satisfy some challenging water infrastructure applications with the V-Cone meter.

Simple Excel Worksheet Predicts Control Valve Aerodynamic Noise

Recently an article was published that presented an easily constructed Excel sheet that estimates hydrodynamic noise in control valves1. A number of people have asked me if there is something similar for aerodynamic noise. 

Parker Instrumentation and Hydrogen Solution | Parker Hannifin

Hydrogen is becoming an increasingly attractive option for many businesses looking to reduce emissions. Parker's H2 range includes products suited to very high pressures and low temperatures, as well as KOLAS, KS ISO and EC79-compliant products and hydrogen service testing options.

How Multipoint Thermocouple Arrays in Amine Units Increase Production and Prevent Failures

Amine units are critical to the operations of refineries and chemical plants. If a unit fails due to corrosion, condensation and foaming, the entire productivity and safety of the facility is imperiled. Temperature measurement solutions allow operators to precisely control amine systems in order to prevent critical failures and maximize efficiency.
