The three major characteristics of orifice meter scale

Abstract: the three major characteristics of orifice meter scale information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Abstract: the orifice meter is relatively less common flowmeter products, a lot of people for its performance and the applicable scope is not very understanding, this article will give you detailed introduces the advantages and disadvantages of it performance HNLG series of orifice flowmeter is the flow of the differential pressure measurement. More flow meter manufacturers choose model price quote you are welcome to inquire, here are three major characteristics of orifice meter scale article details. Orifice meter is relatively less common flowmeter products, a lot of people for its performance and the applicable scope is not very understanding, this article will give you detailed introduces the advantages and disadvantages of it performance HNLG series orifice meter is measured flow differential pressure generator, cooperate with all sorts of differential pressure gauge or differential pressure transmitter to measure all kinds of fluid flow in pipes. Orifice flowmeter throttle device including the ring chamber orifice, nozzle, etc. Orifice flowmeter throttle device with differential pressure transmitter, can measure the rate of flow of liquid, steam, gas, orifice flow meter is widely used in petroleum, chemical, metallurgical, power, light industry and other departments. Fluid filled with pipes, when they flow through the pipe of the throttle device, a beam to local contraction at the throttling of the throttle device, so that the flow velocity increases, the static pressure is low, so the throttling parts before and after the pressure drop is produced, the pressure difference, the greater the flow of medium flow, in the front and rear of the throttling parts the greater the pressure difference, so the orifice meter can be measured by the size of the pressure difference to measure fluid flow. This kind of measurement method based on the energy conservation law and the law of flow continuity as a benchmark. Intelligent throttling device ( Orifice meter) Is integrating flow, temperature and pressure detection, temperature, pressure, and can automatically compensate the new generation of flowmeter, the orifice meter adopts the new technology of advanced computer technology and micro power consumption, strong function, compact structure, simple operation, easy to use. Advantage 1: standard throttling is full, and recognised by the international standards organization, without real flow calibration, can putting-in-service proactively, also in the flow meter is *; 2: the structure is easy to copy, simple, strong, stable and reliable performance, low price; 3: application range is wide, including all the single phase fluid ( Liquid, gas, steam) , partially miscible flow, pipe diameter, working state of the general production process ( Temperature and pressure) Are the products; 4: testing and the differential display instrument can separate different manufacturer production, and specialized production scale. Disadvantages 1: measurement repeatability, accuracy in meter belongs to the medium level, due to the influence of many factors is complex, precision is difficult to improve; 2: narrow range of degrees, because the flow coefficient and Reynolds number, the general range of only 3:1 ~ 4:1; Paragraph 3: have long straight pipe length, generally difficult to satisfy. Especially for large diameter, problems become more prominent; 4: the pressure loss; Line 5: orifice hole within acute Angle to ensure accuracy, so sensitive to corrosion, wear, scale, dirt, use for a long time to guarantee the accuracy need to remove the strong checked once a year; 6: the flange connection, easy to run, run, drip, leak problems, greatly increases the maintenance workload. Three, orifice meter features bring orifice flowmeter throttle device structure easy to copy, simple, firm, stable and reliable performance, long service life, low price. Bring orifice calculation adopt international standards and processing. Bring orifice meter wide scope of application, all the single phase flow are measured, partially miscible flow can also be applied. Bring about standard throttle device without real flow calibration, putting-in-service proactively. Bring orifice meter installation is more simple, do not need to bring pressure tube, can be directly answering the differential pressure transmitter and pressure transmitter. Four, intelligent orifice plate flowmeter features bring about imported monocrystalline silicon intelligent differential pressure sensor. Bring about high precision, perfect the self-diagnosis function. Bring about intelligent orifice plate flowmeter intelligent orifice meter range can be adjusted from the programming. Bring about intelligent orifice meter can display at the same time the cumulative flow and transient flow, pressure, temperature. Bring about have the functions of online, dynamic full compensation, intelligent orifice plate flowmeter has since diagnosis, set range. Bring is equipped with a variety of communication interface. Bring high stability. Bring about wide range range, greater than 10:1. Five, the intelligent orifice meter technical indicators bring about high precision: plusmn; 0. Bring high stability: 075% better than 0. 1% FS/year bring high static pressure: 40 mpa bring set-up work five years in a row without bring negligible temperature, static pressure influence bring about high overpressure resistance above is all there is in this article, you are welcome to inquire me factory flowmeter selection, quotation, etc.
