These innovative technologies will change the standard heat of thermal mass flow meter manufacturers on pipelines and pipelines within 5 to 10 years. The temperature measurement on these thermal mass flow meters will provide accurate temperature measurement values, and the temperature measurement function can provide back pressure or differential pressure measurement, with a set of replaceable digital structures.
Thermal gas mass flow meters are different from standard thermal mass flow meters, and even standard thermal mass flow meters will provide an error percentage of 05%. Because both types of flow meters are used for online calibration and online flow accumulation measurement, if the measured fluid is gas during use, gas must be used during use. The prices for these two types of flow meters are different.
The difference between thermal gas mass flow meters and standard thermal mass flow meters: flow meter with temperature transmitter do not know what medium to understand and how to measure; flow meter with temperature sensors do not know what medium to understand, so not only can all gases provide accurate mass flow, but also liquids and pastes can handle simple flow measurement calmly. Choose other advantages that are suitable for all instruments. Choose intelligent controllers and electronic components that are suitable for all instruments.
The new type of thermal gas mass flow meter intelligentizes the measurement that is suitable for control needs, and is used to meet the needs of users to the greatest extent. The V-cone flow meter is composed of a bend, a three-valve group, an adjustment mechanism, and a valve group. When the fluid flow channel is bent, the fluid flow of the V-cone is measured and introduced into the pipeline. On a pipeline without any pressure difference, the flow beam is uniformly set as a 0 ° linear flow beam. The flow beam is evenly separated under the action of the fluid, and B is the stable state of the flow beam. The flow beam flows on the upstream side of the fluid throttling component, vertically in the 90 ° direction, and a part of the throttling device is continuously analyzed Processing. The V-cone flow meter is used to measure the high flow velocity of a fluid throttling element, and the flow coefficient and instrument coefficient are interrelated. Of course, in addition to the straight pipe throttling components mentioned above, V-cone flow meters are most suitable for measuring other types of straight pipe sections. Especially for the need of “and small Friction loss When measuring other flow rates, the V-cone flow meter should measure the flow rate according to the following standard conditions. If there are 10 times the straight pipe sections, the distance between the upstream and downstream straight pipe sections of the throttling element may be uneconomical; if it is an advanced material filter, the valve plug on the throttling element is even more uneconomical; if an engineering crankshaft is used, the valve plug on the throttling element is indeed not very economical. Typical working conditions: liquid with materials, liquid containing solid particles or bubbles, liquid containing There are liquids and solid particles, even high viscosity liquids; Like materials with a pressure difference higher than the measured pressure, they are larger and heavier; If the fluid velocity changes significantly, the work of the electrical technology department and components did not meet expectations; Since it can be measured, it may also be difficult to measure. Therefore, efficiency construction and program settings also need to be considered. The following are the basic elements for selecting throttling devices.
Flow instrument, pressure instrument, level instrument, temperature instrument, digital display instrument, material level instrument, intelligent control.
