Here are several techniques to measure airflow in an HVAC system. Measure Air Flow with a Device Let’s start with the basics. First, airflow measurement is usually measured in cubic feet per minute, ...

A dirty air probe is required when measuring flow velocity in an operating coal pipe. The dirty air velocities of each pipe should be within 5% of the mean of all the coal pipes to achieve uniform ...

Engineers who need to reduce the energy cost of air compressor systems will find the precision ST50 Air Flow Meter from Fluid Components International (FCI) helps them more accurately measure ...

Rotameter flow meters are devices that can measure the flowrate of liquids and gases. Generally, the rotameter is a tube made of plastic, glass or metal combined with a float, which responds linearly ...

Online burner coal and air flow measurement combined with advanced control strategies have been successfully integrated on multiple units at Progress Energy to reduce carbon monoxide, NO x and LOI.

Omron added a digital flow sensor to its line as an alternative to differential pressure sensors for optimizing energy efficiency in air-conditioning and ventilation systems. ...

Conventional flow sensors use a resistance-measurement method which tracks the electrical resistance change of a material due to changes in temperature. It requires a labor-intensive adjustment of the ...

Uneven distribution of coal flow to burners can lead to higher NOx emissions and increased operating costs. A new laboratory is studying measurement instruments and control approaches to help ...
