The D6F MEMS (microelectromechanical) flow sensors use thermopiles to convert thermal energy into electrical energy. The use of a thermopile allows them to measure airflow and gas-flow speed from 1 mm ...
Knowing if a HVAC system or fan is working efficiently for your customer is important and can be determined by the airflow it produces. Here are several techniques to measure airflow in an HVAC system ...
Global initiatives to reduce greenhouse gas emissions have increased the adoption of precise air flow measurement systems ...
Self-heated thermal airflow sensors are simple, cheap, rugged, and sensitive. However, they exhibit an airspeed to sensor temperature response (King’s Law) that is very nonlinear, as shown in Figure 1 ...
Most residential HVAC contractors and technicians want to do a great job for their customers. Nothing feels better than figuring out the cause of a homeowner’s issue and then implementing the right ...
James, I have a 1988 Corvette Tuned Port Injection (TPI) that randomly sets a code 36: a mass airflow (MAF) sensor function fault. I have replaced the Electronic Control Module (ECM), the mass airflow ...
Zhejiang Geely Holding Group has been granted a patent for a compact assembly that accurately measures air flow in an internal combustion engine’s air intake duct. The assembly includes a housing with ...
Journal of Coastal Research, Special Issue No. 56. Proceedings of the 10th International Coastal Symposium ICS 2009, Vol. I (2009), pp. 366-370 (5 pages) This paper reviews recent progress in ...
MEMSIC's MFC2000 series gas flow sensor measures up to 70 liters per minute of gas flow with a minimal pressure drop. This file type includes high-resolution graphics and schematics when applicable.
