Improving accuracy in analog mass flow measurements 5th order polynomial curve fitting
Analog thermal mass flow instruments perform very accurate and repeatable measurements. These instruments are calibrated to meet an accuracy/linearity specification such as +/- 1% Full-scale. In a typical calibration, ten or twenty representative data points are recorded and analyzed and uncertainties are calculated for each data point referenced to a precision measurement standard. Careful ...

FAQ Corner – Specifying range, pressures on mass flow instruments
We often see the label “One Size Fits All”. This may be fine for some consumer goods. However, it can be quite problematic when applied to items like shirts, gloves, or even golf clubs. “One Size Fits All” also does not work for Mass Flow Controllers (MFC). Not all applications are alike. Forcing a “One Size Fits All” MFC into an unsuitable application ...

Optimizing air flows to aeration basins – Case Study
As a result of clean energy mandates and the rising cost of energy, wastewater treatment facilities around the country are retrofitting their instrumentation to run highly efficient, cost-effective, clean facilities. To reduce emissions and produce clean energy, solid wastes are often digested in large digester tanks to reduce the volume of waste (sludge) and produce more biogas, which is then ...

Air usage data increases company profit - Case Study
A large American container company required mass flow meters on their air compressor lines to help evaluate the efficiency of blow mold machines in their plant. The manufacturer melts PET chips and extrudes them through blow mold machines to produce plastic bottles for the beverage industry. Plant engineers need data on compressed air usage to help them reduce utility and production costs. ...

Gas Blending for Stoichiometry-Part A
How to control the proper ratio of gas flows to achieve proper chemical balance Don’t be intimidated by the fancy Greek name. Stoichiometry just means getting the proper amount of each chemical into a reaction. At a microscopic level it’s balancing a chemistry equation; like to make water (H2O) you need to start with two hydrogen atoms for every oxygen atom. Since hydrogen and oxygen ...

Thermal Mass Flow Meters Improve Efficiency in Wastewater Treatment Plants
Every municipality throughout the country has a wastewater treatment plant to safely treat water that enters back into our environment. This doesn’t mean they are immune to problems. One of the biggest problems for US wastewater treatment plants is the aging infrastructure with an estimated 180 billion dollars needed to repair many wastewater plants. A close second is the energy needed to ...

Core technology part 3: thermal--multivariable mass vortex
In 1997, Sierra Instruments took proven vortex shedding technology to the next level with the launch of the Innova-Mass® Model 240 & Model 241 Multivariable Mass Vortex Flow Meter. Sierra was the first to offer this unique solution for measuring the mass flow of gases, liquids and steam. Vortex shedding flow meters have been in use for many years. The typical device is a flanged in-line ...

Selecting an Airborne Particle Counter: Particles in Process Gases (Series Part 4 of 4)
This blog is about choosing a particle counter for gas applications. First, determine whether your process gas is reactive or non-reactive. Then decide its pressure range. Reactive Gases Examples of reactive gases include hydrogen and oxygen. These gases require a special particle counter stored inside a containment vessel. In addition, they require careful evaluation that the wetted materials ...
