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”
Dwyer Instruments, Inc. was recognized for excellence in product design in the 16th 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 79 entries. The company’s Hydronic Application Software was the Silver Award Winner in the Contractor Services & Software product category. The ACHR News is the leading trade magazine in the heating, ventilating, air conditioning, and refrigeration industries.

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.
Threaded connections are often referred to as a process connection type. For Dwyer product specifications, this connection type is typically NPT (National Pipe Thread), which is an American standard thread. These connections allow products to be installed directly into piping or with the use of threaded fittings.
