Thermal Mass Flow meter Model 780S Flat-Trak™ Inline Mass Flow Meter with Flow Conditioning

FlatTrak™ 780S Overview

Accurate monitoring of peak, low flow and total gas mass flow rates is a critical part of many industrial process control systems. The FlatTrak™ 780S offers improved measurement capabilities in installations where long straight pipe runs are not available. The meter: Incorporates Sierra's unique dual-plate flow conditioning element to eliminate velocity profile distortions, as well as swirl and temperature stratification in the gas stream; Reduces piping straight run requirements to as little as three upstream diameters; Saves you money on installation costs when compared to an orifice-plate where at least 20 upstream piping diameters are required for optimal performance.

Inline Thermal Mass Flow Meters with Flow Conditioning

  • Reduce straight-run requirements with built-in flow conditioning
  • Eliminate drift with DrySense sensor
  • Needs only 3-diameters up, zero downstream
  • Validate in the field for easy in-situ calibration
  • Backed by lifetime sensor warranty

Thermal Mass Flow Meters Offer Oil & Gas Companies Lowest Cost of Ownership

Tuning Your Boiler for EPA Boiler MACT Compliance

The EPA’s Boiler MACT (Maximum Achievable Control Technology) regulations are heating up. Boiler MACT is an EPA rule to limit hazardous air pollutants (HAP) from commercial and industrial boilers and process heaters. Originally published in 2011 as a mandate driven by the Clean Air Act...

Thermal Mass Flow Meters Offer Oil & Gas Companies Lowest Cost of Ownership

The Wall Street Journal recently reported that oil prices have hit a rock bottom $40 a barrel, the lowest since 2009. How does this affect the oil companies? Well, the consumer gets the benefit of the low pump price which does loosen discretionary spending, but the oil & gas companies are hurting-spending less money on capital investment due to tightened budgets.

Why Dry Sensor Design Is Key for Stability, Accuracy and In-Situ Validation

Why Dry Sensor Design Is Key for Stability, Accuracy and In-Situ Validation

Designing a stable sensor that will last over the lifetime of your thermal mass flow meter is the holy grail in thermal mass flow meter design. The truth is that most flow meter manufacturers use a "wet" sensor design, filled with epoxies and cements. As conditions in your application change, the sensor is heated and cooled over time, expanding and contracting the cement inside the sensor—and you know what happens to cement as it is repeatedly heated and then cooled, it shifts and cracks. This "wet" sensor design greatly compromises the accuracy of the thermal sensor over time.

NEW Video Animation: How Do Thermal Mass Flowmeters Work?

As if your were actor Dennis Quaid in the popular 1987 movie Innerspace, journey inside the pipe to learn the operational principle of thermal mass flow technology and see, from a molecules perspective, why thermal flow meters have become extremely popular due to high accuracy, no moving parts, negligible pressure drop, sensitive direct mass flow measurement with high turndown (up to 1000 to 1) giving ability to measure very low to very high flows with the same instrument.

Natural Gas Measurement

Part 1: Challenges with Submetering Natural Gas

Part 1: Challenges with Submetering Natural Gas

In my latest article in Gases & Instrumentation magazine, I explore energy management as it relates to the natural gas industry. Natural gas exists in abundance in this country, with production expected to increase 44 percent by 2040. With such unprecedented growth in production of this natural resource, utility companies must focus on providing the most accurate gas billing possible.

For the First Time, Field-Adjust For Gas Composition Changes, Retain Accuracy, Save Time and Money

For the First Time, Field-Adjust For Gas Composition Changes, Retain Accuracy, Save Time and Money

For the first time, customers can adjust their gas composition in the field on thermal flow meters to solve EPA reporting challenges. When gas composition changes, typical thermal meters must be sent back to the factory to be re-calibrated in order to maintain required accuracy levels.  All of this is a costly, time consuming endevour.

If gas composition changes, field-adjust to maintain flow meter accuracy?

If gas composition changes, field-adjust to maintain flow meter accuracy?

Changes in gas composition cut into productivity in the field, exactly when you need accuracy in flow meter measurement the most. But what if you could retain that precision, even when those changes occur? Now you can do just that with qMix Software.  If your gas composition changes over time, you can now quickly field-adjust the QuadraTherm thermal mass flow meter. You avoid the expense of sending the instrument back to the factory for recalibration by reprogramming it in the field to assure optimum accuracy.
