Orifice type steam flowmeter (measurable)Liquid, vapor, gasThe application of flow in petroleum, chemical, and metallurgical industries

The orifice plate steam flowmeter CS-KB-1810 is a differential pressure generating device for measuring flow rate, which can be used in conjunction with various differential pressure gauges or transmitters to measure the flow rate of various fluids in pipelines. The throttling device includes annular orifice plate, nozzle, etc. The throttling device is used in conjunction with differential pressure transmitters to measure the flow rates of liquids, vapors, and gases. It is widely used in industries such as petroleum, chemical, metallurgy, power, and light industry.When the fluid filled in the pipeline flows through the throttling device inside the pipeline, the flow beam will form a local contraction at the throttling element of the throttling device, thereby increasing the flow velocity and reducing the static pressure. As a result, 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, the size of the fluid flow can be measured by measuring the pressure difference. This measurement method is based on the laws of energy conservation and flow continuity.The intelligent throttling device (flowmeter) integrates flow rate, temperature, and pressure detection functions, and can perform temperature measurement. The instrument adopts microcomputer technology and micro power consumption technology, with strong functions, compact structure, simple operation, and convenient use.

	Characteristics of balanced orifice plate: The significant feature of balanced rectification can maximize the balance rectification of the flow field into an ideal fluid. When the fluid passes through the function hole of the disk, the fluid will be balanced rectified, the vortex will be minimized, and an approximate ideal fluid will be formed. Through the pressure measuring device, a stable differential pressure signal can be obtained, and the volume flow rate and mass flow rate can be calculated according to the Bernoulli equation. balanced flow meteradvantage：1. The measurement accuracy is 5-10 times that of standard orifice plates 2. The flow noise is 1/15 of the standard orifice plate 3. The permanent pressure loss is 1/3 of the standard orifice plate 4. Pressure recovery is twice as fast as standard orifice plates 5. The minimum straight pipe section can be less than 0.51111D
	Characteristics of circular perforated plate: The opening of the circular hole plate is a part of a circle (circular part), and the diameter of this circle is 98% of the diameter of the pipeline. The center of the circular arc of the opening should be accurately positioned to be concentric with the pipeline, so as to ensure that the opening will not be covered by the pipeline and the gaskets at both ends or due to pipeline eccentricity.Suitable for measuring dirty media such as wet gas, it can avoid the accumulation of dirt before and after the orifice plate, and is widely used in the measurement of various gases and dirty fluids. Advantages of circular perforated plate: Pipeline specifications: 50mm ≤ DN ≤ 1200mm Working pressure: PN ≤ 16MPa Working temperature: -40 ℃ ≤ t ≤ 450 ℃ Accuracy level: Level 1, Level 1.5 Connection methods: clamp type, flange connection, welding type.
	Characteristics of flow restriction orifice plate: Due to its advantages of simple structure, easy processing, low manufacturing cost, and convenient installation, the use of flow limiting orifice plates instead of regulating valves to limit flow or reduce pressure, while meeting process requirements, will greatly reduce investment and operation maintenance costs. Therefore, it has been widely used in process equipment abroad and plays an important role in the safe operation of the equipment. Advantages of flow restriction orifice plate: 1. In situations where process materials require pressure reduction. 2. When a large pressure drop is required upstream and downstream of the valve in the pipeline, in order to reduce the erosion of the valve by the fluid, an orifice plate can be connected in series upstream of the valve when throttling through the orifice plate will not produce gas phase. 3. Places where fluids require low flow and continuous flow, such as pump flushing pipelines, bypass pipelines for hot standby pumps (low flow protection pipelines), analysis sampling pipelines, etc. 4. Places that require pressure reduction to reduce noise or wear, such as venting systems.
