An integrated electromagnetic flowmeter measures the actual mass of gas passing through the measuring instrument per unit time. The unit is calculated in standard liters per minute (slpm) or standard cubic centimeters per minute (sccm), which are SI units. Common British units include standard cubic feet per minute (scfm). In both cases, the standard refers to the standard reference conditions of temperature and pressure. This allows more common industrial measurement terms to be easily converted into integrated electromagnetic flowmeters. What is a turbine flowmeter? A turbine flow meter measures the volume of fluid that passes per unit of time. There are many units of measurement for volumetric air flow. Some common examples include cubic feet per minute (cfm) and cubic centimeters per minute (ccm). The integrated electromagnetic flowmeter technology is inherently superior to turbine flowmeter technology because it can address the issue of absolute measurement. Common process gases such as air, argon, carbon dioxide, as well as 2, N2, and oxygen, follow the principles of the ideal gas law. Although not all gases are ideal, these common gases operate on the principle of changes in density caused by changes in temperature and pressure. Since changes in temperature and pressure (T&P) affect gas density and thereby reduce accuracy, volumetric air flow rates are not as reliable for absolute measurements as integrated electromagnetic flowmeters. Turbo flowmeter measurement requires T&P compensation to determine the true integrated electromagnetic flowmeter.
