The Intricacy of Proper Instrumentation in Cleaning Produced Water

The cleaning of produced water during oil and gas production and exploration is a crucial, although costly endeavor. In the process of bringing oil and gas up to the surface from a well, several byproducts are also produced. Water is the largest of these byproducts by volume, with 882 billion gallons produced per day. This produced water contains a variety of other compounds and substances, including organic and inorganic compounds, grease, bacteria, and dissolved solids such as iron.

Magnehelic® Differential Pressure Gage Minor Divisions Update

Magnehelic® Differential Pressure Gages, Series 2000

Over the years, Dwyer Instruments, Inc. has continuously improved its position as a global leader in designing and manufacturing innovative controls, sensors and instrumentation solutions. This success is due in part to our invention of the Magnehelic® differential pressure gage in 1953. Since then, the market leading Magnehelic® differential pressure gage has been continuously updated and improved. The Magnehelic® gage is a versatile low differential pressure gage which quickly indicates air or noncorrosive gas pressures – either positive, negative (vacuum) or differential. Over the years, among countless other updates, we’ve invented a high accuracy version of the Magnehelic® gage which provides an accuracy within 1% of full scale and created backwards compatible products.

Market Shifts & the Need for Backward Compatible Products

Technology markets shift.  The shift can be incremental, radical, or sometimes disruptive.

Take, for instance, gages used in process automation markets. Gages command about $3.5 billion in global instrument sales, the major portion, over $11 billion now held by transmitters.

The technological shift from a visual indication gage to the first transmitter has been incremental. It has taken over 50 years for transmitters to go from concept to commanding 70% market share. Continue reading “Market Shifts & the Need for Backward Compatible Products”

Flow Measurement with Orifice Plates

Dwyer Instruments, Inc. offers many types of flow measuring products including orifice plates, which are used as a flow sensing element with a differential pressure monitor.

Orifice Plates

Orifice plates are a primary flow element, detecting the flow of a fluid passing through the plate by sensing the pressure drop across the plate. When a fluid flows through a restriction in a pipe, it creates a pressure difference between upstream and downstream of the restriction. This pressure difference is proportional to flow rate according to Bernoulli’s principal, similar to a Pitot tube.  Orifice plates are commonly used as they are simple to use, low cost, work with gases or liquids, and require low maintenance.  Adversely, they do have large pressure losses with about 50% of the pressure drop not recoverable.  Continue reading “Flow Measurement with Orifice Plates”
