Shanghai XingshenSharing: When fluid flows through the throttling device inside the pipeline, it causes local contraction near the throttling element, increases the flow velocity, and creates a static pressure difference on both sides upstream and downstream.
orifice plate flowmeterThe throttling device has a simple and sturdy structure, stable and reliable performance, long service life, and low price. It is a commonly used flow measuring instrument in industry. The entire processing process adopts standards and undergoes strict calibration and testing.
orifice plate flowmeterBy increasing the flow rate and lowering the static pressure, a pressure drop, or pressure difference, is generated before and after the throttling element. The larger the flow rate of the medium, the greater the pressure difference generated before and after the throttling element. Therefore, orifice flow meters can measure the size of fluid flow by measuring the pressure difference. This measurement method is based on the laws of energy conservation and flow continuity.
orifice plate flowmeterIt can measure the flow rate of various fluids in pipelines, including liquids, gases, and vapors, and is widely used in industrial sectors such as petroleum, chemical, metallurgical, light industry, and coal mining.
orifice plate flowmeterA static pressure difference is generated before and after, which has a certain functional relationship with the flow rate. The larger the flow rate, the greater the pressure difference The differential pressure signal is transmitted to the differential pressure transmitter, converted into a 4-20mA. DC analog signal output, and transmitted remotely to the flow integrator to achieve fluid flow measurement Mass flow meter, using intelligent differential pressure transmitter, automatically compensates for operating temperature/pressure to achieve measurement of fluid mass flow rate
orifice plate flowmeterTo deliver hot air, the hot blast stove is generally closer to the blast furnace and has more bends. In the past, standard orifice plates were used, but the error was significant due to the insufficient length of the straight pipe section. This instrument requires a 2D long straight pipe section due to the presence of a pressure equalization ring and multiple pressure taps. After installation on the air supply duct of the hot blast stove, the application situation is very satisfactory. More than thirty hot blast stoves have been equipped with annular orifice flow meters and have been running for more than three years.
