应用范围
To ensure an optimum combustion process in a coal-fired power plant, the amount of air flowing in the pipes leading to the furnace must be carefully monitored. A Venturi section of the air pipe is a defined constriction in which the pressure drops a few millibars proportional to flow rate. VEGADIF 65, with its especially small measuring range and high accuracy, measures this pressure drop with great precision and calculates the air flow.
