New Developments In Thermal Dispersion Mass Flow Meters
This paper describes a newly developed microprocessor-based thermal dispersion mass flow meter that uses four temperature sensing elements in its flow sensor instead of the traditional two elements and automatically manages changes in gas selection, gas temperature, gas pressure, and outside temperature. By John G. Olin, Ph.D., Founder/Chairman, Sierra Instruments
A Tale Of Two Thermals: Capillary And Immersible
For gas mass flow measurement and control, Sierra offers the broadest selection of thermal mass flow measurement products on the market. By Mark McMahon, Scientific Product Manager, Scott Rouse, Industrial Product Manager, Sierra Instruments
In-Situ Calibration: Methods And Pitfalls Of Thermal Mass Flow Meter Sensor Field Validation
Mid-to-large size facilities and campuses inevitably have hundreds of ow instruments to monitor, maintain, and repair. For a reliability engineer, ensuring that all instrumentation meets ISO 9000 or similar standards is a time-consuming responsibility. By Matthew J. Olin, President & CEO, Sierra Instruments, Inc.
4 Keys To Great Portable Ultrasonic Flow Metering
The liquid measurement market is an extremely large market with many varied measurement requirements. To get the best bang for your buck, a portable ultrasonic flow meter is a practical solution. With a portable ultrasonic flow meter, you can use one liquid flow meter in several locations throughout your flow process.
Best Practices for Mass Flow Controller Manufacturing
In Part 1 of our mass flow controller best practices series, Best Practices for Mass Flow Controller Selection and Installation, Sierra’s Chief Engineer John Smitherman compiled a comprehensive list of best practices for the selection, installation and operation of mass flow meters and controllers. With so many flow measurement products and technologies on the market, it’s important to also be able to assess the manufacturer,
How To Save Time & Money By Calibrating Flow Meters Onsite
If you have hundreds of mass flow controllers and meters or just a few in your lab, facility, or manufacturing process, how do you keep up with the demands of annual recalibration?
Introducing A New Paradigm For Thermal Dispersion Mass Flow
Since the publication of the American Society of Mechanical Engineers (ASME) standard on thermal dispersion mass flowmeters in 2011, there have been major advancements in the technology. A review of that standard and a discussion of technology advancements provide the background to understanding groundbreaking innovations in sensor design. That, along with a comprehensive algorithm facilitated by current hyper-fast microprocessors, has created a new paradigm for the measurement of the mass flow rate of gases by means of thermal dispersion technology. By John G. Olin, Ph.D., Sierra Instruments, Inc.
Precise Biogas Flow Measurement
As oil prices remain high, we are in the midst of a nation-wide initiative to seek renewable sources of energy to increase energy efficiency and energy security. Renewable energy accounted for 13.2% of the domestically produced electricity in 2012. Among the sources of renewable energy is the production of biogas from landfill gas (LFG) or digester gas. By Scott Rouse, VP Product Management, Sierra Instruments
How Thermal Mass Flow Meter Technology Works
In this NEW video from Sierra, you’ll learn the operational principles of thermal dispersion mass flow technology.
Optimizing Air Flows To Aeration Basins
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 used as fuel in the cogeneration process. However, a clean environment calls for not just clean air and clean energy, but clean water as well.
