Belimo has released new larger sizes of inline flow sensors, 2.5 inch to 6 inch, that offer automatic glycol measurement and compensation for optimal system performance. Belimo officials said the flow sensors utilize ultrasonic technology with glycol compensation to provide accurate and repeatable flow measurements of water and water/glycol mixtures without drift in any HVAC application.

What risks are being taken to not measure/monitor/control airflow directly and who is at risk?

While yesterday’s engineers have made great progress, we’re just cracking the surface, and the future relies on the experimental efforts of today’s engineers.

Sensaphone® has added two new sensors to its line of remote monitoring equipment for HVAC applications. The Sensaphone Duct Mount Air Flow Transmitter measures the rate of airflow and alerts users when conditions fall outside of the preset threshold. The transmitter monitors the presence or absence of cool moving air and measures relative airflow from 0-16 meters per second.

Extech Instruments launched the Extech TH30, RHT30, and RHT35 compact dataloggers. The new family of three environmental recording instruments is designed to provide HVACR professionals with easy access to real-time temperature, humidity, and barometric pressure readings as well as insights compiled from extended readings preformatted in Excel® or PDF® report formats.

TSI has introduced its wireless AirPro™ Instruments Platform. According to the company, the AirPro Instruments are wireless velocity and pressure measurement tools that maximize productivity by offering easier measurement access, accuracy, seamless multi-data reporting, and more.

Greenheck has expanded its Air Measuring Damper (AMD) line with the addition of the AMD-TD series of thermal dispersion-based airflow measuring dampers. The AMD-TD series combines the functionality of a highly-accurate thermal dispersion airflow station and a low-leakage control damper to control airflow volumes to a target set point.
