The Orifice Flowmeter Is Strong And Has A Long Service Life

The fluid flows through the throttling device in the pipeline, causing local contraction near the throttling part, increasing the flow velocity, and generating a static pressure difference between the upstream and downstream sides.
The throttling device of the orifice flowmeter has a simple structure, firmness, stable and reliable performance, long service life and low price. It is a flow measuring instrument commonly used in the industry. The entire processing process adopts international standards and has undergone strict calibration and testing. .
The orifice flowmeter increases the flow rate and lowers the static pressure, so a pressure drop occurs before and after the throttle, that is, a pressure difference. The greater the flow rate of the medium flow, the greater the pressure difference before and after the throttle, so the orifice Plate flow meters can measure fluid flow by measuring differential pressure. This measurement method is based on the law of energy conservation and the law of continuity of flow.
The orifice flowmeter can measure the flow of various fluids in the pipeline. The measurable media include liquid, gas and steam. It is widely used in petroleum, chemical industry, metallurgy, light industry, coal mine and other industrial sectors.
There is a static pressure difference before and after the orifice flowmeter. There is a certain functional relationship between the pressure difference and the flow rate. The greater the flow rate, the greater the pressure difference. The differential pressure signal is transmitted to the differential pressure transmitter and converted into 4-20ma. The DC analog signal output is transferred to the flow totalizer remotely to realize the measurement of fluid flow. The mass flowmeter uses an intelligent differential pressure transmitter to automatically compensate the working condition temperature/pressure to realize the measurement of fluid mass flow,
The orifice flowmeter needs to send hot air, and the hot air stove is generally close to the blast furnace, and there are many elbows. In the past, standard orifice plates were used, and the error was large because the straight pipe section was not long enough. Because the instrument has a pressure equalizing ring and multiple pressure-taking ports, it only needs a 2D long straight pipe section. After being installed on the air supply pipe of the hot blast stove, the application condition is very satisfactory. There have been more than 30 hot blast stoves equipped with annular orifice flowmeters, and they have been running for more than 3 years without failure.
