VII: Selection Guide for Split Steam Flowmeter Products :
According to the structural characteristics of the steam flowmeter of the intelligent vortex flowmeter series, it is classified into two types: integrated and split.
高能电池或24VDC (通常在需要脉冲信号输出、二线制420mADC输出或RS485通讯时采用)供电,就地液晶显示介质温度(℃)【或工作压力( MPa )】、瞬时质量流量( Kg/h )和累计质量流量( Kg )。 When measuring saturated steam in an integrated manner, it integrates a vortex flow sensor, temperature sensor (or pressure sensor) and a display instrument, with intelligent temperature (or pressure) compensation function. It comes with a 3.6V high-energy battery or 24VDC (usually when a pulse signal is required Output, two-wire 4-20mADC output or RS485 communication) power supply, local liquid crystal display medium temperature (° C) [or working pressure ( MPa )], instantaneous mass flow ( Kg / h ) and cumulative mass flow ( Kg ).
高能电池或24VDC (通常在需要脉冲信号输出、二线制420mADC输出或RS485通讯时采用)供电,就地液晶显示介质温度(℃)、工作压力( MPa )、瞬时质量流量( Kg/h )和累计质量流量( Kg )。 When measuring superheated steam in an integrated manner, it integrates vortex flow sensor, temperature sensor, pressure sensor and display instrument into one, with intelligent temperature and pressure compensation functions, comes with 3.6V high-energy battery or 24VDC (usually when pulse signal output, two-wire system 420mADC output or RS485 communication) power supply, local liquid crystal display medium temperature (℃), working pressure ( MPa ), instantaneous mass flow ( Kg / h ) and cumulative mass flow ( Kg ).
)】、瞬时质量流量( Kg/h )和累计质量流量( Kg )。 When measuring saturated steam separately, it is composed of vortex flow sensor, temperature sensor (or pressure sensor) and intelligent flow display totalizer. It has intelligent temperature (or pressure) compensation function and is remotely displayed by the intelligent flow display totalizer. Medium temperature (℃) [or working pressure ( MPa )], instantaneous mass flow rate ( Kg / h ) and cumulative mass flow rate ( Kg ).
)、瞬时质量流量( Kg/h )和累计质量流量( Kg )。 When measuring superheated steam separately, it consists of four parts: vortex flow sensor, temperature sensor, pressure sensor and intelligent flow display totalizer. It has intelligent temperature and pressure compensation functions. The intelligent flow display totalizer remotely displays the medium temperature (℃ ), Working pressure ( MPa ), instantaneous mass flow ( Kg / h ), and cumulative mass flow ( Kg ).

)和累计工况体积流量( m3 )。 It is important to point out that when only the volumetric flow rate of the working condition is required (we define it as a simple type, which is generally applicable to the occasion where the medium temperature and working pressure are basically constant), whether it is integral or split, it does not have Intelligent temperature and pressure compensation functions, and no temperature sensor and pressure sensor configuration. At this time, only the instantaneous working condition volume flow ( m3 / h ) and cumulative working condition volume flow ( m3 ) are displayed.

    Temperature and pressure compensation integrated intelligent vortex flow sensor is based on a new design concept. It integrates temperature, pressure, and flow signals into one. The three signals are mixed and processed by an intelligent digital processor to output a compensated standard flow. Realized the temperature and pressure compensation function for gas and steam. Due to the intelligent integration design concept, the temperature and pressure compensation intelligent vortex street has the characteristics of compact structure, convenient installation and maintenance.

Measuring range:
℃、工作压力为1个大气压)下的体积流量。 In order to facilitate the selection, we will simply define the volume flow rate under the working condition of steam as the volume flow rate under the working condition (actual medium temperature and working pressure), and simply define the standard volume flow rate as the standard condition (media temperature is 20 ℃) , Working pressure is 1 atm) volume flow.
Working condition volume flow measurement range
Specification working principle and structure

    个柱形阻挡物,在其后部(相对于流体流向)两侧就会交替地产生旋涡。 In the fluid pipeline, a cylindrical barrier is inserted vertically, and vortices are alternately generated on both sides of the rear (relative to the direction of fluid flow). As the fluid flows downstream to form a vortex train, we call it Carmen Vortex Street. We define the cylindrical barrier that generates the vortex as a vortex generator. Experiments show that under certain conditions, the frequency of vortex separation is linear with the flow velocity of the fluid. Therefore, as long as the frequency of vortex separation is detected, the flow velocity or flow rate of the fluid in the pipeline can be calculated. Vortex flowmeters are manufactured on this basis.

 

Eight: Installation requirements of split steam flow meter:

     The direction of the flow arrow on the vortex flowmeter is consistent with the flow direction of the fluid, and its installation angle is not limited.

  40DN ,下游直管段长度5DN The length of the upstream straight pipe section is 15-40DN , and the length of the downstream straight pipe section is 5DN

  5DN处,取压孔通径为612mm ,测温点设置在下游68DN处。 When pressure and temperature compensation is needed, a pressure transmitter and temperature transmitter should be equipped. The position of the pressure relief hole is 3-5DN downstream of the sensor, the diameter of the pressure hole is 6-12mm , and the temperature measurement point is set downstream. 6-8DN .

   On-site installation must be far away from the vibration source if it meets the above installation requirements.

Advantages of vortex flowmeter :
Advantages of vortex flowmeter: The structure of vortex flowmeter is simple and sturdy, and it is easy to install and maintain. Compared with the throttling differential pressure flowmeter, there is no need for pressure guiding tube and three valve groups, which reduces leakage, blockage and freezing. There are many types of fluids, such as liquid, gas, vapor, and some miscible fluids. 、范围宽度可达101201 、压损小。 Precision is high, R is the measured value, the range width can reach 10 : 1 or 20 : 1 , and the pressure loss is small. The output pulse signal is proportional to the flow rate, suitable for total measurement, no zero drift; within a certain Reynolds number range, the output frequency signal is not affected by the fluid physical properties and components, that is, the meter coefficient is only related to the vortex generator and the pipeline Shape and size are related, just need to check in a typical medium and apply to a variety of media. The corresponding detection method can be selected according to the measurement object, and the instrument has strong adaptability.

  Nine: Precautions for purchasing and selecting split steam flow meters:
The selection of flow meters often plays an important role in the successful use of the meters. Due to the complex conditions of the measured objects, the variety of meters, and the performance indicators, the selection of the meters is difficult. There is no perfect flow meter, and all types of meters have their own characteristics. The purpose of selection is to choose the most suitable meter from among the many varieties to avoid weaknesses.
General selection can be considered from five aspects, which are instrument performance, fluid characteristics, installation conditions, environmental conditions and economic factors. The five factors are detailed as follows:
仪表性能方面 1 instrument performance
Accuracy, repeatability, linearity, range, flow range, signal output characteristics, response time, pressure loss, etc .;
流体特性方面 2 Fluid characteristics

安装条件方面 3 installation conditions
过滤器、消气器) 、安装、等; Pipe arrangement direction, flow direction, length of the straight pipe section on the upstream and downstream sides of the test piece, pipe diameter, maintenance space, power supply, grounding, auxiliary equipment ( filters, getters ) , installation, etc .;
环境条件方面 4 Environmental conditions
Ambient temperature, humidity, electromagnetic interference, safety, explosion protection, pipeline vibration, etc .;
经济因素方面 5 Economic factors
Instrument purchase costs, installation costs, operating costs, calibration costs, maintenance costs, instrument life, spare parts, etc.

The selection steps are as follows:
依据流体种类及五个方面考虑因素初选可用仪表类型(要有几种类型以便进行选择)1. Primary selection of available instrument types based on fluid type and five considerations ( there are several types for selection ) ;
对初选类型进行资料及价格信息的收集,为深入的分析比较准备条件; 2. Collect data and price information for the primary selection type, and prepare conditions for in-depth analysis and comparison;
采用淘汰法逐步集中到12种类型,对五个方面因素要反复比较分析最终确定预选十:目标. 3. Use the elimination method to gradually focus on 1 to 2 types, and repeatedly compare and analyze the five factors to determine the pre-selection ten: target .
