Orifice bimetallic thermometer in the application of natural gas industry

In recent years, despite the many new bimetallic thermometer gas measurement, such as: ultrasonic bimetallic thermometer, gas turbine bimetallic thermometer, etc. But due to the orifice bimetallic thermometer measurement technology has a long history, wide application range, simple structure, long service life and low price, and the standard orifice bimetallic thermometer can be identified without calibration, signal, Differential pressure) Relationship with the flow and estimate its measurement error, etc, in the bimetallic thermometer is unique. It is because of these reasons, in the future for quite a period of time, due to various factors, especially before calibration cannot obtain proper solution, orifice bimetallic thermometer is still is the main gas measuring instrument. Orifice bimetallic thermometer occupy a large market in the current natural gas measurement. At the same time, as a result of automation technology in orifice bimetallic thermometer measurement system, the application of the orifice bimetallic thermometer measurement system to overcome the unfavorable factors such as traditional human error in the process of measurement, to further improve the measurement accuracy of the orifice plate bimetallic thermometer. 3 oh magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer

orifice bimetallic thermometer flow measurement range extension method improvement in oil and gas measurement, the flow rate change is big, the traditional approach is also equipped with many pieces & beta; Value tied for several different orifice or bimetallic thermometer. New intelligent orifice bimetallic thermometer in bimetallic temperature using extended function of differential pressure decomposition system on a computer, don't have to change the orifice plate and differential pressure transmitter can be completed; Another extension function is the expansion of large lateral flow measurement range, this is the differential expansion, so that the large lateral flow measurement to expand the scope of a system. Plus ultra wide range, range than the maximum can reach 1:18 0, USES two differential pressure transmitter, their burden with small flow range and large flow range measurement, signal independently, bimetallic temperature computer convert the signal into different areas to choose, and in all areas of calculus, which make the super wide range measurement also can guarantee higher accuracy. Although many devoted one differential pressure transmitter, but with two parallel bimetallic thermometer equipment costs, compared to both improve the economic efficiency, and save the trouble of switching back and forth; Compared with using the method of multiple orifice block, to avoid the orifice plate replacement, reduce the difficulty of the operation. 3 oh magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer

today's development trend is integration, high precision and wide than new bimetallic thermometer, and a perfect bimetallic temperature compensation function, the computer software is a powerful function, at the same time equipped with RS485 communication interface standard computer, can be connected to the DCS communication, provide a convenient to maintenance, convenient and practical in the process of industrial production of magnetic flap thermometer. At the same time, as a result of the new differential pressure transmitter can simultaneously measure the differential pressure, static pressure and temperature, gas pressure, temperature, corrected and the cell or to measure gas mass flow rate, reduced the number of independent sensors, simplifying the pipeline project, reduce the cost of installation; Reduce pipeline opening, reduce potential leakage points, improve overall can be *, the orifice bimetallic thermometer for better application provides * technology guarantee. In natural gas flow measurement by orifice double metal thermometer, such as the orifice of the bimetallic thermometer (a device Orifice throttling device) And secondary instrument ( Differential pressure, static pressure, temperature, gas physical parameters measuring instruments, etc. ) Supporting the instrument selection, design, installation and use are in strict accordance with the relevant standards, and in a controlled state, when using the flow measurement accuracy can be controlled in & plusmn; ~ ± 1%; 1. Within the scope of 5%. 3 oh magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer

with gas bimetallic temperature measurement is a kind of indirect, multi-parameter measurement, dynamic, cannot reproduce, the bimetallic temperature measurement of natural gas is one of the difficulties of the flow measurement. Therefore, when choosing a specific solution, the reliability of the system should be considered, accurate, and sophistication. When the choice must consider the possibility of natural gas metering transition way change and the possibility of real-time measurement compensation, such as online chromatographic analysis, real-time compensation, energy metering, etc. If you want to on the basis of the enterprise information network, based on enterprise information network as the link of station control system, should consider to achieve data remote metering system configuration. 3 oh magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer
