7: Split Steam Flow Meter Product Selection Guide
:

According to the structural characteristics of the steam flow meters in the intelligent vortex flow meter series, they are classified into integrated and split types. Two kinds.

When measuring saturated steam in an integrated manner, it integrates the vortex flow sensor, temperature sensor (or pressure sensor) and display into one, has intelligent temperature (or pressure) compensation function, and comes with a high-energy battery or (usually When pulse signal output two-wire system or R communication is required, the power supply is adopted. The local LCD displays the medium temperature (°C) [or working pressure] instantaneous mass flow rate (/) and cumulative mass flow rate.

When measuring superheated steam in an integrated manner, it integrates a vortex flow sensor, a temperature sensor, a pressure sensor and a display instrument. It has an intelligent temperature and pressure compensation function and comes with a high-energy battery or (usually when a second line of pulse signal output is required) The power supply is used when controlling ~ output or R communication, and the local LCD displays the medium temperature (°C), working pressure, instantaneous mass flow (/) and cumulative mass flow.

When measuring saturated steam in a split type, it consists of three parts: a vortex flow sensor, a temperature sensor (or pressure sensor) and an intelligent flow display calculator. It has an intelligent temperature (or pressure) compensation function and consists of an intelligent The flow display calculator remotely displays the medium temperature (℃) [or working pressure] instantaneous mass flow (/) and cumulative mass flow.

When measuring superheated steam in a split type, it consists of four parts: a vortex flow sensor, a temperature sensor, a pressure sensor and an intelligent flow display calculator. It has an intelligent temperature and pressure compensation function and is remotely controlled by the intelligent flow display calculator. Displays medium temperature (°C), working pressure, instantaneous mass flow (/) and cumulative mass flow.
What needs to be pointed out in particular is that when it is only required to measure the volumetric flow rate under working conditions (we define it as a simple type, which is usually suitable for situations where the medium temperature and working pressure are basically constant), whether it is an integrated or split type , none of them have intelligent temperature and pressure compensation function, and there is no configuration of temperature sensor and pressure sensor. At this time, only the instantaneous working condition volume flow rate (/) and the cumulative working condition volume flow rate are displayed.
The integrated intelligent vortex flow sensor with temperature and pressure compensation uses a new design concept to integrate temperature, pressure and flow signals into one, and uses an intelligent digital processor to mix and process the three signals and output a compensated standard flow rate. , thus realizing the temperature and pressure compensation function of gas vapor. Due to the intelligent integrated design concept, the temperature and pressure compensated intelligent vortex street has the characteristics of compact structure, easy installation, use and maintenance. Functional features of temperature and pressure compensation integrated flow meter

Measuring range:

In order to facilitate selection, we simply define the volume flow rate of steam as the volume flow rate under working conditions (actual medium temperature and working pressure), and the standard The volume flow rate under normal conditions is simply defined as the volume flow rate under standard conditions (medium temperature is ℃ and working pressure is 1 atmosphere).

Working condition volume flow measurement range

Specification working principle and structure
In the fluid pipeline, insert a cylindrical barrier vertically, at the rear (relative to (in the direction of fluid flow) vortices will be generated alternately on both sides. As the fluid flows downstream, a vortex array is formed, which we call a Karman vortex street. We define the cylindrical obstruction that generates vortices as a vortex generator. Experiments have shown that under certain conditions, the separation frequency of vortices has a linear relationship with the flow rate of the fluid. Therefore, as long as the frequency of vortex separation is detected, the flow rate or flow rate of the fluid in the pipe can be calculated. Vortex flow meters are manufactured based on this principle.

8: Installation requirements for split steam flowmeter:
① 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 restricted.
②The length of the upstream straight pipe section, the length of the downstream straight pipe section
③When pressure and temperature compensation are required, a pressure transmitter and a temperature transmitter should be equipped, and the position of the pressure relief hole is downstream of the sensor. The diameter of the pressure hole is , and the temperature measurement point is set downstream.
④ During on-site installation, if the above installation requirements are met, be sure to stay away from the source of vibration.
Advantages of vortex flowmeter:

Advantages of vortex flowmeter: The vortex flowmeter has a simple and solid structure, and is easy to install and maintain. Compared with the throttling differential pressure flowmeter, it does not require pressure guidance. Pipes and three-valve groups, etc., to reduce leakage, blockage and freezing. Applicable to many types of fluids, such as liquids, gases, vapors and partially miscible fluids. High accuracy generally means that the R range width of the measured value can reach: or: small pressure loss. It outputs a pulse signal proportional to the flow rate and is suitable for total quantity measurement. There is no zero point drift within a certain Reynolds number range. The output frequency signal is not affected by the physical properties and components of the fluid. That is, the instrument coefficient is only related to the shape of the vortex generator and the pipe. Size-related, it only needs to be calibrated in a typical medium and is applicable to various media. The corresponding detection method can be selected according to the measurement object, and the instrument has strong adaptability.
9: Things to note when purchasing a split steam flow meter:

The selection of a flow meter often plays a very important role in the successful use of the meter. Due to the complexity of the measured object The conditions and various performance indicators of instruments make the selection of instruments difficult. There is no perfect flow meter. All types of instruments have their own characteristics. The purpose of selection is to choose the most suitable instrument among the many varieties by leveraging their strengths and avoiding weaknesses.

General selection can be considered from five aspects, which are instrument performance, fluid characteristics, installation conditions, environmental conditions and economic factors. The detailed factors in the five aspects are as follows:

Instrument performance

< br/>Fluid characteristics

Temperature, pressure, density, viscosity, chemical corrosion, abrasive scaling, miscible phase change, conductivity, sound speed, thermal conductivity, specific heat capacity, isentropic index

Installation conditions

Pipe layout direction, flow direction, length of straight pipe section upstream and downstream of the test piece, pipe diameter, installation of power supply grounding auxiliary equipment (filter eliminator) in the maintenance space, etc.

Environmental conditions< br />
Ambient temperature, humidity, electromagnetic interference, safety, explosion-proof pipeline vibration, etc.

Economic factors

Instrument purchase fee, installation fee, operation fee, calibration fee, maintenance fee, instrument Lifetime spare parts, etc.
The steps for selection are as follows:

Select the available instrument types based on the type of fluid and five considerations (there must be several types to facilitate selection

Collect data and price information for the preliminary types to prepare conditions for in-depth analysis and comparison

Use the elimination method to gradually focus on ~ types, and repeatedly compare and analyze five factors to finally determine the preliminary ten: Goal
