Turbine flow meter liquid flows through the turbine housing causing
an internal rotor to spin. As the rotor spins, an electrical signal
is generated in the pickup coil. This signal is converted into
engineering units (liters, cubic meters, gallons etc.) on the local
display where is applicable. Optional accessory modules can be used
to export the signal to other equipment. It has the features, such
as high accuracy, good repeatability, convenient
installation/maintenance, simple structure etc.
Product features
1.The impeller of the sensor is made of special alloy bearing,
which has good wear resistance and long precision.
2.Simple and firm structure, easy to assemble and disassemble and
clean.
3.Multi point nonlinear correction, high precision, data power down
for 10 years.
4.A variety of signal output, suitable for different occasions.
Working Principle
The LUGB type vortex flowmeter is a flowmeter designed and
manufactured using the Karman principle theory of the relationship
between the generation of vortices and the flow rate. It can be
used to measure the flow of steam, gas and low viscosity liquids. A
triangular column (vortex) generating body is inserted into the
fluid, and a regular Karman vortex is formed alternately behind the
triangular prism, and the separation frequency of the scoring is
proportional to the flow velocity(V) of the measured medium.
Therefore, the flow rate of the measured fluid can be calculated by
detecting the number of vortices by the flow meter sensor head, and
the signal processing circuit calculates the volume flow rate of
the measured medium according to the sensor aperture.
Product Feature
1.High accuracy and good repeatability
2.The detection element is not in contact with the fluid, and the
performance is stable and the reliability is high.
3.Simple and firm structure, movable parts, reliable operation for
a long time
4.Wide measurement range with a range ratio of 1:10 (special up to
15)
5.The pressure loss is small, about 1/4~1/2 of the orifice
flowmeter
