Steam flowmeter selection, what are the commonly used steam flowmeters?

A steam flow meter is named after the measuring medium, which means that it can measure the flow rate of steam. According to the classification of Vton steam flowmeter, steam flowmeter includes: imported steam vortex flowmeter, imported orifice flowmeter, elbow, power bar, float type and rotor flow, etc.

When measuring steam flow, which steam flowmeter to choose, how to choose, the method provided by our Weidun VTON engineers, generally consider the measurement accuracy, easy installation and use and reasonable product to make a decision.

If it is helpful to you, please raise your hand and give Weidun VTON valve a thumbs up.

The importance of steam flowmeter selection: the measurement effect of the flowmeter is determined by two aspects. One is the instrument, that is, high precision; Second, the installation should be in accordance with the installation requirements of the manual.

Only if these two aspects are met, then the measurement of the meter must be accurate. The buyer must provide the necessary parameters to the instrument manufacturer, including the instrument installation site, pipeline distribution, surrounding environment and other information. Fully consider all aspects that may affect the metering, and finally determine the selection of a flow meter as the measurement according to the performance of various flow meters.

I want to install a steam flowmeter on the 2t and 6t steam boilers, the steam pressure is, how to choose? It would be nice to be able to provide a sample. My mailbox.

And how to choose a feed water flow meter? It would be nice to be able to provide a sample. I can't send a sample here, you can find the way of Weidun vton online.

The temperature of the steam is usually between 100-250 and the pressure is generally. This has determined the three elements of the working condition of the flowmeter, and the next selection problem is very simple.

Commonly used flowmeters for steam include differential pressure flowmeter, vortex flowmeter, turbine flowmeter, etc. Among them, the accuracy level of differential pressure flowmeter is the highest, such as the V-cone flowmeter with the highest accuracy in differential pressure flowmeter.

If the diameter of the pipeline in the field is small, the vortex flowmeter is a cost-effective choice. Especially between the common calibers of DN25-DN300, vortex flowmeters are the most widely used to measure steam flow.

Therefore, to choose a suitable flowmeter model for measuring steam flow, the key is the working environment and budget.

The steam flowmeter can choose the vortex street flowmeter and the differential pressure flowmeter, depending on your site conditions. Usually, the vortex flowmeter has high accuracy and large range ratio. However, if the temperature is too high (more than 350 degrees), the pressure is too large (more than 40 kg), or the pipeline has obvious mechanical vibration, the flow rate is too large, and the diameter is more than 250mm, you had better choose a differential pressure flowmeter (orifice plate, nozzle, V-cone, etc.), and the differential pressure flowmeter is stronger and more durable than the vortex flowmeter.

Orifice plates and vortex flowmeters for steam measurement.

Among them, vortex flowmeter is more common, which is mainly used for flow measurement of industrial pipeline medium fluids, such as gas, liquid, vapor and other media.

The steam flowmeter is a special instrument for measuring the cumulative mass flow rate of steam, which has two structural forms: mechanical and intelligent; The mass of all steam flowing through the meter can be accurately read out by means of a live display on the indicator dial (mechanical) or LCD (intelligent), and a pulse signal can also be output, with manual pressure compensation or automatic temperature compensation.

Due to the simple structure, moderate price and wide measurement range of the flowmeter, it is widely used in petroleum and petroleum, chemical, textile, heating and other occasions that require steam flowmeter.

The vortex flowmeter is a volumetric flowmeter that measures the volumetric flow rate of gases, vapors or liquids, the volumetric flow rate of standard conditions or the mass flow rate according to the Karman vortex principle. It can also be used as a flow transmitter in an automated control system.

Steam measurement is generally done with an orifice flowmeter, which is more commonly used, and steam is very difficult to measure accurately!

There are many flowmeters that can measure steam, such as vortex flowmeter, orifice flowmeter, differential pressure flowmeter, porous balance flowmeter, thermal gas mass flowmeter, V-cone flowmeter, etc.

The correct selection of vortex flowmeter is a prerequisite for ensuring the good use of vortex flowmeter, and important factors need to be considered: passage (DN), installation method, medium temperature, output signal, and medium type.

Hello,The brand manufacturer of steam flowmeter imported from the United States with a good reputation for customers - KNKEGlad for your question.

First, let's start with the medium

The measured steam is superheated steam or saturated steam, how high is the temperature of the steam, if the normal 250 below can choose the vortex flowmeter, if the temperature is too high such as 400, then we should consider choosing the V-cone or orifice flowmeter.

Second, measure the pressure of the pipe

The pressure of steam is a very important aspect, usually the pressure is very large, it is about 1MPa, it is okay to choose a vortex flowmeter, then if it exceeds this pressure, such as 4MP, 6MPa, then our suggestion is to choose a V-cone and orifice flowmeter.

Inlet orifice flowmeter.

Again, the question of measuring caliber

Vortex flowmeters can usually only measure pipe diameters below DN300, if you choose a large diameter plug-in vortex flowmeter, or an orifice flowmeter.

Finally, we also need to take into account the current operating conditions and temperatures

Before installing the flowmeter, we have to investigate whether the surrounding environment is suitable for the installation of the flowmeter, if there is an interference source that will affect the accuracy of the measurement, the requirements of the straight pipe section are also very important, there are the requirements of the first 10 and the last 5, which is suitable for the pipeline environment, and the flowmeter of the KNKE brand is also an important aspect to consider.

Steam flow = flow rate cross-sectional area density.

According to the steam temperature and pressure, the steam density is detected, and the cross-sectional area is calculated according to the pipe diameter, and the steam flow rate is generally 5-50m s, and the steam flow rate can be calculated.

According to the pressure and temperature, the various types of steam are classified as: saturated steam, superheated steam.

A steam flow meter is an instrument or device that specializes in measuring the flow rate of steam. It determines the flow rate of steam by measuring parameters such as its mass, volume, or velocity, and transmits the results to other devices or systems in a digital display or via an output signal.

A steam flow meter usually consists of the following main components:

1.Flow sensors: used to measure parameters such as the mass, volume or velocity of steam. Commonly used steam flow sensors include differential pressure flowmeter, vortex flowmeter, thermal flowmeter, ultrasonic flowmeter, etc.

2.Signal converter: converts the steam flow signal collected by the flow sensor into a standard electrical signal output, such as 4-20mA, 0-10V, etc., for transmission and processing.

3.Indicator or indicator: Used to display real-time steam flow values, usually in the form of numbers or graphs.

The working principle and specific type of steam flow meter are somewhat different. Differential pressure flow meters calculate flow by measuring the pressure difference created when steam flows through a pipe; The vortex flowmeter estimates the amount of flow by detecting the frequency of vortex flow when steam flows. Thermal flow meters infer flow rates by measuring the temperature changes that occur when steam flows through a sensor; Ultrasonic flow meters calculate the flow rate by sending and receiving ultrasonic signals to measure the speed and direction of vapor flow.

Steam flow meters are widely used in industrial and commercial applications, especially in steam generators, heating systems, energy metering, environmental protection, and other fields. They provide accurate measurement and monitoring of steam, helping to optimize system operation and control costs and energy consumption.

The steam flowmeter is a special instrument for measuring the steam flow rate and total amount, which can be widely used in energy, chemical industry, metallurgy, light industry and other industries and environmental protection projects. It is developed according to the principle of Kármán vortex, and uses piezoelectric stress sensor and microprocessor microprocessor to process the signal, which has the characteristics of small size and low pressure loss. According to different application scenarios, the scope of application of steam flowmeters includes the measurement of high-viscosity liquids, the measurement of high-temperature and high-pressure gases, the measurement of low-temperature liquids, and the heat meter of wax gas transportation.
