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.
We recently met with a customer in India who needed to replace a flowmeter in an Energy Monitoring System (EMS) application in a commercial shopping mall.
Energy Monitoring Systems (EMS) continuously monitor and record chiller operating data. The EMS utilizes flowmeters installed in each chiller to measure flow. Temperature sensors are located in the inlet and outlet of the evaporators and condensers. A kWh meter measures the power consumption of each chiller. The data from each of these devices is collected and recorded within the control panel, which is then sent to a report generated in the cloud. This kind of system can accurately report the data used to manage energy and operating costs.
