Abstract:
     The invented equipment for in-line measurement of parameters (pressure, temp, density, humidity, mass flow and heat value) of wet steam in industrial pipeline is composed of critical flow Venturi nozzle, electric pressure transducer, speed tester (for example orifice-plate throttle unit), electric differential transducer and operation display. The steam measurer uses such characteristics as under a certain pressure when wet steam passes through critical flow Venturi nozzle, the passed mass per unit time is a constant value and the amplitude of pressure difference created on passing through speed tester is decreased with the increasement of density.
