Dwyer Instruments, Inc. 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”
Selecting the correct flowmeter can be a challenging task, and the variety of flow technology options can make the decision even more difficult. By keeping the benefits and drawbacks of each type in mind, you will be able rest easy knowing you’ve made the best choice for your application.
Calibration is the comparison and adjustment of a reading from an instrument in correlation with the reading of a higher accuracy piece of equipment. The overall goal of this process is to minimize measurement uncertainty and ensure the accuracy of an instrument.
Insertion flowmeters provide a great alternative to inline flowmeters because they are typically less expensive and easier to install than inline meters. But how do you know which type of insertion meter to choose?
