In the process of using the steam flowmeter, we may encounter some minor failures, do not panic after the problem, find out how to deal with is the key. The following introduces several common faults of steam flowmeters and their solutions.

1. After power-on, there is fluid flow in the pipeline, but the vortex flowmeter has no signal output

Whether the temperature and pressure compensation is required for steam measurement by vortex flowmeter mainly depends on the properties of the steam being measured and the requirements of measurement accuracy.

Vortex flowmeter is widely used because of its wide range, small pressure loss, medium accuracy, linear output, no moving parts, high reliability, small maintenance, medium low price, relatively high performance and price characteristics.

The working principle of vortex flowmeter is to place a non-streamlined vortex generator in the fluid, so that the fluid is alternately separated on both sides of the generator, releasing two series of regularly staggered vortex flowmeter. In a certain range, the vortex separation frequency is proportional to the flow rate, and the flow rate of the medium can be measured by calculating the vortex separation frequency.

Vortex flowmeter is a kind of flow measuring instrument widely used in the industrial field. Its superior performance and versatility make it play an important role in the measurement of liquid and gas medium. Vortex flowmeter can not only measure a variety of liquid media, but also suitable for a variety of gases, providing reliable flow data support for industrial production and process control.

Vortex flowmeter is also known as Karman vortex flowmeter. Vortex flowmeter is a kind of separation flowmeter made by using the principle of natural oscillation of fluid. When a fluid flows at a sufficiently large velocity through an object perpendicular to the direction of the fluid, if the object is of appropriate size, it will produce a neatly aligned and reversed vortex train behind the object along two parallel lines.

Compressed air is generated by air compressor or high pressure fan. When these devices are in operation, they all have varying degrees of vibration, and sometimes the vibration is relatively strong, and this vibration is transmitted through the connecting pipe.

The main advantage of the temperature and pressure compensated vortex flowmeter is that the instrument coefficient is not affected by the physical properties of the measured medium and can be extended from one typical medium to other media.

Temperature and pressure compensation integrated vortex flowmeter performance advantages:

The installation of the vortex flowmeter has different provisions, used to measure different measured media, different positions, then the installation method is not the same, the attention point is different, generally speaking, the vortex flowmeter has the following specified points:

Vortex flowmeter is based on the Karman vortex street principle, which is mainly performed by setting a non-streamlined vortex generator (resistance fluid) in the flowing fluid, and alternately producing two columns of regular vortices from both sides of the vortex generator.

Vortex flowmeter is mainly used to set up a vortex generating body (resistance fluid) in the fluid, from both sides of the vortex generating body alternately to produce regular vortices, to measure the flow of fluid, vortex flowmeter is mainly used for industrial pipeline fluid flow measurement, such as gas, liquid, steam and other media. It is characterized by small pressure loss, large range, high accuracy, and is almost not affected by fluid density, pressure, temperature, viscosity and other parameters when measuring volume flow under working conditions. In daily use, the output signal may be unstable, causing this phenomenon to be excluded from the following points:

When choosing the right ammonia flow meter for you, several factors need to be considered to ensure the accuracy of the measurement results and the reliability of the equipment. Here’s a detailed buying guide:

In modern industrial production, efficient and accurate flow measurement is the key to ensuring process stability and improving energy efficiency management. Vortex flowmeters, with their advantages of simple structure, high reliability and wide application range, have become the “main force” in flow monitoring in industries such as petrochemicals, energy and power, metallurgy and pharmaceuticals, providing solid support for the intelligent upgrade of industry.

In the field of industrial gas flow measurement, vortex flowmeters, with their simple structure, high stability and wide application range, have become the ideal choice for monitoring the flow of various gases such as natural gas, steam and compressed air. Based on the Karman vortex street principle, it calculates the flow rate by detecting the vortex frequency generated when the fluid passes through the blocking fluid, and can achieve high-precision measurement without temperature and pressure compensation. The following is an analysis of the typical applications and technical advantages of vortex flowmeters in gas measurement.

The vapor flowmeter has no moving parts, strong reliability, high precision, long life, and can measure the instantaneous flow and cumulative flow of liquid in a wide flow range.

Vortex flow meters offer a host of advantages that make them a preferred choice in various industrial applications. One key advantage is their versatility in measuring the flow of liquids, gases, and steam. Unlike some other flow measurement technologies, vortex flow meters can handle a wide range of fluids, making them suitable for diverse industries such as oil and gas, water treatment, chemical processing, and HVAC systems.

The vortex flowmeter has a flow meter in the pipeline without output. The reasons for this failure and the corresponding solutions are as follows:

In the process of diameter selection of vortex flowmeter, special attention should be paid to the fact that the diameter of vortex flowmeter cannot be selected according to the original pipe diameter on site. The diameter of the vortex flowmeter should be determined according to the parameters in the pipeline such as the flow range of the medium in the pipeline, working temperature and working pressure, and then combined with the technical parameters of the vortex flowmeter.

Vortex flowmeter is widely used because of its wide range, small pressure loss, medium accuracy, linear output, no moving parts, high reliability, small maintenance, medium low price, relatively high performance and price characteristics.
