Advantages of Sensor Technology: Accuracy and Meter Calibration

Posted by TechStar on Jun 14, 2022 3:48:00 PM

The accuracy of a thermal mass flow meter is dependent upon the technology type and the quality of the materials used for the meter’s sensor design. A well-designed sensor is made to measure flow accurately over a long period of time with minimal drift, independent of recalibration and calibration validation diagnostics. For a thermal mass flow meter, the materials used in the manufacture of the sensor play a vital role in the overall performance of the sensor. The materials must create the best environment for heat transfer - the essential principle of thermal mass flow measurement - or the accuracy and response time suffer.

Five Mistakes When Selecting a Flowmeter

Posted by TechStar on Feb 3, 2022 10:12:00 AM

Flowmeters play a critical role in today’s process world. As technology has advanced through the decades, a variety of flowmeter technologies has expanded the ways, customers, control and monitor their utilities, steam, fiscal metering, etc. Today, a few of the top flowmeters on the market are the Coriolis, magnetic, vortex, ultrasonic, differential pressure, and variable area meters. Several other technologies, such as turbine, thermal mass, and positive displacement, are also available. Since each flowmeter has positive and negative attributes, careful consideration is required to avoid purchasing a technology that is inappropriate to the application.

Understanding Flow Meter Accuracy Specs

Posted by TechStar on Sep 9, 2021 9:55:00 AM

What is Flow Rate and Why is It Important in Process Applications?

In an industrial setting, controlling processes with accurate data is an essential part of keeping the process running smoothly. Control systems are equipped with instrumentation like thermal flow meters to feed flow data like gas temperature and gas flow rate into the system. So, what is flow rate and why is it important? The flow rate of the gas tells the system how much of a gas is flowing through a cross section of a pipe at a prescribed unit of time. Flow rate data can help with many things, including the following:

Direct Mass Measurement of Flare & Combustor Gas Flow Rates

Posted by TechStar on Nov 18, 2020 8:42:00 AM

Providing exceptional low-flow sensitivity for accurate measurement over a wide range of flaring operations

Flare stacks and combustors are used to burn waste gases from the plant, converting chemical and organic hydrocarbons into primarily water vapor and CO2. Some processes also use relief valves to vent flammable gases to the flare stack during upset conditions.

Applications include oil and gas well drilling operations, oil refineries, chemical process plants, gas distribution infrastructure, and landfills. Flares are subject to stringent regulations, requiring operators to measure, record and report the amount of flared gases.

Due to the potential for large changes in flow rates, density, pressure and gas composition, flare gas measurement is one of the most difficult and demanding flow applications. Fox Thermal flow meters have demonstrated their ability to measure the low-flow rates typical of normal flare conditions, and also the high velocities found in upset conditions.

Fluid composition and installation anomalies can also affect flow meter performance. Fox Thermal's calibration lab employs a wide range of gases, gas mixtures, temperatures, pressures and line sizes to simulate actual fluid and process conditions. This real-world approach improves installed accuracy and minimizes measurement uncertainty.

Fox Flow Meter Advantages in Emissions Monitoring Applications

  • Exceptional low-flow sensitivity for accurate measurement over a wide range of flaring operations

  • Stainless steel sensor is suitable for corrosive, particulate-laden gas streams

  • No temperature and pressure compensation required

  • Direct mass flow measurement

  • Built-in alarms, totalizers and a wide variety of communications protocols available for easy interfacing with emissions management systems

Typical Applications Include:
  • Oil and Gas Well Drilling Operations (On and Off shore)

  • Oil Refineries

  • Chemical/Petrochemical Processing Plants

  • Gas Distribution Infrastructure

  • Landfills

Custody Transfer Flowmeters – An Evolution in Technology

Posted by TechStar on Nov 12, 2019 10:58:00 AM

Custody Transfer (also known as Fiscal Metering) in the oil & gas industry refers to the transactional transfer of a substance, raw or refined, from one party (owner) to another.

Typically when a custody transfer is taking place, the end goal is to determine the value or payment between two parties for the physical substance (gas or liquid) that has exchanged hands via pipeline. For that reason, the flow instrument that measures the total amount of product changing ownership can be viewed as a cash register between the two parties.

The Best Conditions for Correct Process Control

Posted by TechStar on Oct 16, 2019 1:30:00 PM

Optimum control of production to avoid unnecessary costs

Raw materials and end products are accepted, processed, stored and delivered in almost all industrial processes. In order to optimally control production while avoiding unnecessary costs and ensuring product quality, the volume flows must be recorded correctly and seamlessly. This task should be solved as precisely as possible and with minimum pressure losses. The application-specific parameters must, of course, be taken into account, such as the type and composition of the medium to be measured, process pressure and temperature range.
