As a flow rate measuring device, the design of the engine's Verabar flowmeter for measuring displacements, for example from structural features. Due to the special structure of the flow meter design, it actually shows that it has other advantages of reliability accuracy, excellent pressure, temperature, and corrosion. Measured engine performance, emissions, one of the main parameters required to measure exhaust flow. However, the direct measurement of the exhaust gas flow is a more difficult characteristic of the engine exhaust gas. Displacement to reflect, as well as fuel consumption under normal conditions, but the amount of air flow, strictly speaking, measured exhaust does not take into account the amount of engine leakage, so you may not be accurate. Since the displacement must be measured directly, in general, the supercharged engine is continuously used in the exhaust gas recirculation test, exhaust gas recirculation, exhaust gas dilution measurement of the engine exhaust. It may be at idle temperature. First, the orifice temperature of the orifice flowmeter engine, the temperature difference between the exhaust and the exhaust, can be higher than 800°C, and the maximum temperature is at full load (full speed): the flow of engine exhaust Measurements, the following questions directly, 150 °C, need to take into account that the exhaust resistance increases because the increase in the engine's fuel consumption rate, because in the increase of the exhaust gas supply, the power engine is pushed next, measuring the displacement of the engine it is not possible to produce Too much, the third resistance, which can be corrosion of the flowmeter has particulate matter and strong acids, such as the exhaust of the engine, and the temperature of the gas in the exhaust gas increases, worsening the emission measurement displacement adds meaninglessness may cause congestion in the hole mmima The flow cytometer or the flow meter changes the state of the exhaust gas of the engine, and because of the discontinuity of the exhaust gas at the engine, in particular, the exhaust pulsation of the exhaust pressure caused before is large, in particular, there is a Exhaust turbochargers and unsupercharged engines.
The flow meter (Werabar) designed for measuring power bars in this article is new and measures the accuracy of exhaust flow measurement equipment. The single power flow meter is the principle of differential pressure. When the fluid flows through the sensor, the front (facing the direction of flow), which reads with the Verabar flowmeter sensor, and the rear exhaust pipe to generate a high voltage sensor distribution with a low set pressure distribution from the high pressure area In a regular array of multiple specific (usually three double) heights, the fluid pressure in the flow direction facing the end of the measurement, each fluid pressure is generated to a pressure tap for each point (including velocity pressure and static The average value of the pressure may be the point at which the dynamic pressure) P1 pressure value has been measured. Static pressure measures the average fluid at multiple points, the only hole in the low pressure zone of the pickup (downstream direction), that is, the sidewall of the lower pressure value P2. P2 is the pressure difference of ΔP = P1-P2 and P1, which is introduced into the differential pressure transmitter and the average speed, that is, ΔP can be estimated from the analysis of the pressure average flow rate reflected by the fuel metering principle of the fuel dispenser. The flow rate of the fluid. The flow sensor produces a stainless steel corrosion-resistant metal that has a special cross-sectional shape, as shown in Figure 2 just Power Bar. The point of separation of the fluid at the low pressure port and the probe, before the high pressure port, are located on the lateral sides of the probe in front of the probe. The metal surface in front of the probe is roughened. According to the principle of aerodynamics, the fluid at low speed allows the probe to obtain a stable flow of fluid through the rough surface, forming a turbulent boundary layer that is stable and conducive to improving the state of measurement accuracy at low rotational speeds. The proportion of more and more, accurate differential pressure signal. The Power Bar Flow Sensor design is such a major attempt to prevent the impact. However, if the hydrostatic pressure in the pipeline, the fluid flow sensor operation, began to enter the hollow hole high pressure probe, forming a pressure equilibrium immediately, after which he has formed an equilibrium state pressure long and high pressure port shunt Involutes leave no input in the vortices formed on both sides of the back of the probe toward the probe, and the enthalpy is detected at the inlet of the high pressure fluid. Under normal conditions, particulate impurities are concentrated under the action of the probe portion at the lower rear side, and the vortex is pulled. In order to avoid the eddy current low pressure port, to achieve the nature of the land, due to the awakening of the separation point of the fluid port and the low pressure side of the probe front, etc. as the impurity in the avoided accumulation area, the signal generated by the current changes . Therefore, it is very stable to prevent a pressure difference signal from being generated by a flow sensor that blocks the fundamental PowerBar flowmeter. We increase the number of holes to be used for large diameter gas measurement structures, cross-type sensors, and pressure to overcome the causes of ineffective precision rectifiers. The structure, the location of the tube velocity sensor in the center of gravity, is such that the placement of a plug-in is caused by the sensor's flow cross-sectional area as small as possible so that together, using some very small pressure loss. The aging test bed catalytic converter system is shown in FIG. In order to ensure that the specific catalytic converter bed ageing test than the airspeed specific test in the engine design, with the two required catalytic converters were tested at the same time, compare the flow balance of the two tubes required by the test, discharge I think Calculations. To artificially accelerate the aging process, such as exhaust gas, in order to increase the exhaust temperature, we must measure exhausted flow. Flow Measurement Engine Exhaust Pipe, Power Bar Flow Meter, Flow Measurement of Hot Exhaust Gas, Engine This article is a thorny issue to solve a particular problem, and sometimes measured by the exhaust flow is accurate and good for the effect I achieved.
