Question: Can the standard Series 160 Pitot Tubes be used to sense liquid flow as well as gas flow? Continue reading “Ask the Expert – Sensing Liquid Flow with DS Flow Sensor”
Question: I have a new project coming up, and I am considering using the Series RHP Humidity/Temperature Transmitters. However, the instrumentation needs to be suitable for use in a hazardous area. Would the Series RHP work, or do you have a different instrument that you would recommend for this application? Continue reading “Ask the Expert – Hazardous Area Humidity/Temperature Transmitter”
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.

Dwyer Instruments, Inc. was recognized for excellence in product design in the 14th annual Dealer Design Awards Program sponsored by The Air Conditioning Heating & Refrigeration News Magazine (The ACHR News). An independent panel of contractors acted as judges in the contest that had 81 entries. Three Dwyer products stole the spotlight this year: the PredictAir™ Application Software; the Series AVUL, Air Velocity Transmitter; and the Series 490A-HKIT, Hydronic Differential Pressure Manometer. ACHR News is the leading trade magazine in the heating, ventilating, air conditioning, and refrigeration industries.
Dwyer Instruments offers several flow measuring products that use a thermal sensing element.
Thermal dispersion flow sensors use a temperature element that is heated up beyond the media temperature. Based on calorimetry, the flow moving past the sensor will have a cooling effect that is directly proportional to the flow velocity. The heat is convected from the heated probe surface to the boundary layer of the fluid flowing over the heated surface. Continue reading “Thermal Dispersion Flow Switches”
