Measuring Steam Mass Flow with Linear Orifice Differential Pressure Flowmeter

Using a linear orifice plate differential pressure flowmeter to measure steam mass flow, if the post-stage instrument flow calculator accepts the differential pressure signal through digital communication, there will be no loss of accuracy at all. And if it accepts the differential pressure signal with its analog input population, because of the IV 8 and 8/! ) for two conversions, the corresponding precision is lost. The loss of this accuracy is about 0.35^ in the interval of high relative flow rate, and the influence is significantly increased in the interval of low relative flow rate, and the smaller the relative flow rate, the smaller the effect. Therefore, it is recommended to use digital quantity to transmit differential pressure signal. The biggest shortcoming of the traditional orifice flowmeter is that when the measured flow is small relative to the full-scale flow, the differential pressure signal is very small, which greatly affects its range and measurement accuracy. People have developed a variable area and variable pressure head orifice flowmeter on the basis of the traditional orifice differential pressure flowmeter. Because there is a linear relationship between the output differential pressure signal and the measured flow rate, it is also called a linear orifice differential pressure flowmeter. Working principle of linear orifice flowmeter Linear orifice is also called elastic loading variable area and variable pressure head orifice. The annular gap area changes automatically with the flow rate. The curved conical plug moves back and forth under the action of differential pressure spring force. The change of the ring gap makes the output signal (differential pressure) and the flow rate linear, and greatly expands the range. Its structure is shown in Figure 3.4.
