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

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,N2, CO2 and so on. 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.
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
