Vortex Flow Meters

 

 

The Vortex flow meter is the only type of flow meter that can measure all three fluid phases – liquid, gas, and steam. Vortex flowmeters make use of the only flow measurement technology capable of performing steam flow measurement in one integrated package; this ability makes it the best and most economical solution for steam flow measurement. The vortex meter can also be offered with integrated pressure and temperature measurement for both compressed gas and steam flow measurement in order to allow the meter to compensate for variations in pressure and temperature that will affect volumetric flows of compressible media. The vortex meter’s no-moving-parts design provides users with reliable, maintenance-free operation and long service life even in dirty and contaminated media applications.

SMARTMEASUREMENT™ VORTEX FLOW METERS

Vortex flow meters

The primary application for vortex flow meters is steam because no other flow meter can measure steam with only one sensor. Other technologies such as DP flow meters, etc. must use, flow, temperature and pressure to measure standard steam flows. The SmartmeasurementTM ALVT standard vortex meter measures steam flow at a fixed pressure and temperature.  In applications where pressures and/or temperatures are not constant, our ALVT-mass Vortex flow meters is ideal because it has a fully integrated pressure and temperature sensor to compensate for dynamic process changes. They are also ideal for gas mass flow measurement. The ALVT vortex meter’s no-moving-parts design provides users with reliable, maintenance-free operation with long service life even in dirty and contaminated media applications.

Key Applications

Magnetic flowmeters from SmartMeasurement have been successfully installed in a wide variety of industries and applications including:

How to choose a
vortex flow meter

The primary source of energy is using fossil fuel plants that uses steam to generate electricity. The ALVT Vortex flow meters are ideal for steam measurement as well as offering many advantages including easy installation without impulse lines, no moving parts to maintain or repair, less leak potential and a wide flow turndown range. Vortex meters also offer very low power consumption as compared to other flow measurement devices.  For steam measurement, the only alternative to vortex metes is a differential flow measuring device which must have several sensors to equal the output of a vortex flowmeter. In applications where process conditions such as pressure and/or temperature are not constant,

SmartmeasurementTM offers a fully compensated ALVT-mass flow meter with an integrated pressure and temperature sensing device. Vortex flowmeters are the absolute flow measurement choice for steam applications. 

Special Cases

The SmartMeasurementTM Multi-Variable Vortex Meter or the ALVT-mass automatically adjusts for changes in density, making it easy to accurately measure mass and corrected volume in steam and gas applications. Steam measurement requires highest safety and reliability and our proprietary all-cast design, gasket- free, sealed meter body eliminates leak points offers users ease of mind. Moreover, having no moving parts or need to install impulse lines means fewer process upsets and smoother operations.

Application and Installation Techniques

Smart vortex meters employ the vortex flow measurement technique combined with a microprocessor-based flow computer which automatically corrects for insufficient straight pipe conditions inside its’ flow body as well as diagnostic information which can identify problems with both the meter and with the application.

Mass flow vortex meters include integrated pressure and temperature sensors to detect process pressure and temperature in addition to the vortex frequency. With the ability to measure the media pressure, temperature, and velocity, the mass flow vortex meter is able to determine the density and the mass flow rate. Typical accuracies for this style of meter are 1.25% of reading for measuring the mass flow of liquids and a 2% of reading for gases and steam. The multi-parameter capability of this meter provides an additional benefit for applications where knowledge of process pressure and temperature is required or is of value for other reasons. In those situations, a mass flow vortex meter provides a convenient, less costly alternative to installing separate transmitters.

Steam measurement is the most popular application for vortex flow meters as they are far more economical and easier to install versus other flow measurement technologies that have the ability to measure steam.  However, for compressed gases, the vortex meter has low flow and low-pressure limitations. For liquids, some vortex meter manufacturers are unable to cancel out electrical noise, which can be considerable in liquid applications.  Moreover, batch control applications must be avoided as it takes approximately 30 seconds or more to stabilize a flow rate reading.  This is because vortex sensing meters count the number of vortices in a moving average technique in order to determine an instantaneous flow rate.
