Vortex shedding flow meter

STLU Series vortex flowmeter is a very versatile flow meter that can be used for flow metering, measurement and control of virtually all gases, liquids and vapors. It is worked on Karman Street principle and is a kind of volumetric flow meter.A Vortex flow meter is a type of flowmeter that has changed and improved over the years. This flow meter is designed to measure the volume, mass flow of liquids, gases, and vapors, and it all does according to the Karman vortex principle. The Vortex type flow meter is used to measure the flow rate of a gas or liquid in a fully flowing pipeline. They have a high accuracy class because of the advanced differential algorithm used for flow calculation.Vortex flow sensor has high signal insulation and resistance to vibration and noise. Electronic vortex flow transmitter can display the linear value of the compensated mass flow. It is most commonly used to measure steam or vapor flow because of its accuracy.

Currently we have various style vortex flow meters for different application

In-line vortex flow meter and insertion vortex flow meter
In-line vortex flow meter can be thread, wafer, flanged or tri-clamp process connection
Normal temperature (250°C) vortex flow meter or high temperature vortex flow meter
Economical frequency type vortex flow sensor or various output vortex flow transmitter
Internal temperature and pressure compensation or only one kind compensation, such as only temperature compensation or only pressure compensation, or no compensation type
Electronic Vortex flow metershave pulse, frequency or 4-20mA output or Hart ,Modbus

Features

The fluids working temperature can be high, the medium temperature can reach 350 °C or even higher;
No moving parts, no wear on the sensor, it performance with high reliability
The pressure loss is small
Easy flow meter construction and convenient to install
Output pulse signal is proportional to the flow, no zero drift
All stainless steel flow meter, standard 304 SST, option with 316 or 316L, it is corrosion-resistant flow meter

how does a vortex flow meter work ?

Turbulence-based flow meters (Vortex) are used to measure higher fluid flow rates. A barrier is inserted into the tube, behind which it is created turbulent motion, then the Vortex frequency is directly proportional to the velocity of the fluid. Signet 7000/7001 is a Vortex flow sensor that has no moving parts and uses a natural phenomenon that occurs in the form of a source (Vortex) when fluid flows downward from a fixed object.

Vortex flow meter applications

Applications of the Vortex flow meter are large and are very important in many industries. Calculation methods are particularly significant because gas and liquid prices are determined based on flow through pipes. The Vortex flow meter is mainly used to measure the flow of steam, gas (air), and non-conducting liquids,Large applications, Vortex flow meter for natural gas , vortex steam flow meter or vortex air flow meter. It is mostly used in the mechanical industries to measure the flow of saturated and superheated water vapor, as well as feed water. It is applicable in all areas of the process, chemical and pharmaceutical industries where hygiene conditions are of great importance. The Vortex flow meter can be used to measure the flow of various industrial waters, including the measurement of circulating water, wastewater, and waste liquids in the production process of the chemical industry, light industry, electricity, metallurgy, construction materials, and oil. It is used to measure the flow of oils such as gasoline, kerosene, diesel, as well as the viscosity of heavy oil.

Vortex Mass Flow meter

Silver Automation Instruments offer vortex flow meter with temperature and pressure correction, so that the vortex flow meter can calculate the mass flow of the fluids passing, we often use it to measure steam, to calculate the mass flow ,ton/hour or kg/hr. Vortex steam flow meter is a perfect solution for saturated vapor or over heated vapor mass flow measurement.

Vortex air flow meter

Vortex flow meter can be used to measure air, compressed air volume flow or mass flow. Vortex flow meter is a low cost air flow meter and gas flow meter, can be wafer or flange connections, digital vortex flow meter with electronic display to show air flow.

There are many benefits of the Vortex flow meter:

  • The sensor does not directly contact the medium, and its performance is stable and long life;
  • It has a simple and solid structure, no moving parts, and this makes it easily portable for long work;
  • Vortex flow transmitter with 4-20mA pulse , or pulse output , or RS485 or Hart protocol
  • Pressure loss is low, operating costs are low, and save more energy;
  • Its maintenance is not difficult, and installation costs are low;
  • The measurement range is wide and can be up to 1 to 10;
  • A wide range of applications;
  • It is easy to sterilize;
  • A linear relationship between flow and measured value;
  • Transfer temperatures are from -200 to 400 degrees;
  • High resistance to temperature and hydraulic shock, as well as pipeline vibration;
  • The Vortex flow meter has intelligent instrumentation and a digital LCD screen that is connected to an automation system.

Vortex flow meter price

Vortex flow meter price is affected by many factors:


  • 1. Flow meter sensor size? Obviously, the larger, the cost is higher.
  • 2. Vortex flow meter functions, such as RS485 or Hart
  • 3. Whether need temperature and pressure correction integration with Vortex Flow meter
  • 4. Whether high temperature and high pressure type
  • 5. Material request
