The choice of throttling device and use
With the development of modern industrial production, the automation degree of information technology more and more high, how to choose a different implementation in different operating conditions of the throttle device for the precision and stability of the flow measurement is very important. Different throttling device applicable in different operating conditions of the throttle device types and different effect. Now industrial process high requirement of accurate measurement of parameters, including flow is a very important parameter. In standard orifice plate and nozzle for the throttle device of traditional measurement has a simple structure, high temperature resistant, long service life, the advantages of stable and reliable, but there are disadvantages is also very obvious. SIKE measurement and control technology co., LTD. Development and design new meter instrument which integrated throttle device (porous balance meter, nozzle, circular orifice) with distinctive features and technical advantages such as the throttle device is widely used in many industries. Based on the different characteristics and their advantages and disadvantages of the throttle device, according to various working conditions to choose the suitable throttling device of flow measurement, can get accurate and stable measurement results.
The following through on different medium flow at different operating conditions of measurement, a brief introduction to the integration of throttling device. Due to the integration of the throttle device solve the problem, leakage, frozen wall, has the advantages of guard against theft, large range, and solved the problem of the balance. So better suited to apply to the steam flow measurement, providing relatively is indoor measurement used, such as straight pipe conditions meet the requirements under the premise of using integrated throttle device is the best solution.
In addition, because the integration of the throttle device design is an organic whole, in be used actually install do not need to three valve group, the guide pipe, including instrument protection box, meter to save the investment has also reduced the installation and maintenance workload.
Using gas measuring instrument type are many, but the dominant position of the orifice flowmeter throttle device. Because of the pressure of the gas medium is generally low, the differential values are smaller. Besides medium instrument is dirty wet gas, easy production plugging phenomena, so the V cone throttling device is more suitable for measuring pressure is low, the dirty wet gas.
Industrial production process often arise when some special condition, straight pipe is difficult to meet the requirements, wide range than, the flow measurement accuracy and high, in this case choose to balance the flowmeter to measure is very ideal, of course, has its drawbacks as well as balance meter, such as for dirty wet gas measurement is prone to blocking phenomenon. So in used in special conditions, general throttling device can meet the conditions in addition to the dirty wet gas conditions other than balance meter for throttling device for the gas medium is the best solution.
Through the simple can understand the general situation of the integration of the throttle device, in the conclusion of different working condition as far as possible when the flow measurement, combining with the characteristics of all kinds of throttling device has to choose the appropriate throttle device, will be able to play in traffic detection to best measurement result.
