Product Description
General
LXW- Series vortex flowmeter is manufactured and designed according to the principle of Kamen vortex flow. Put a drum vertically into a burette and let some fluid flow down along the drum, by two sides of which there formed, in rotation, regular vortexes , which is called the Karman Street. A output frequency of the Karman Street is related to fluid velocity and drum diameter,
Where,
 
f=St·v/d
 
f-Output frequency of the Karman Street    
St-Coefficient (called as Strohar number)   
v-velocity
d-Diameter of drum
 Water Flowmeter Lxw-Vortex Flowmeter
Q = f/k  
Note:     Q: the quantity flow
f: the frequency of the flow
k: the instrument coefficient

 Water Flowmeter Lxw-Vortex Flowmeter

As a output frequency of the Karman Street f is direct proportional to a velocity v. It may work out an instantaneous flow rate by using a tested output frequency of the Karman Street. The Strohar number is a key coefficient for vortex street flow meters. Within the lineal section of the curve, where St≈0.17, the output frequency is direct proportional to the flow velocity, so a velocity v is derivable by using a tested frequency f.
 

1.1 Feature                                          

  •  Compact and durable, high reliability, with no movable parts, can be stably used in a long run.
  • Easy to install and maintain
  • No direct contact between transducer and tested material, reliable and have a long life circle.
  • Output is a pulse signal that is proportional to traffic; has high precision and no zero offset.
  • A Large rang of measurement with up to 1:10 rang ratio.
  • Lower pressure loss and operating cost makes more sense on energy saving.
  • Within certain rang of Renault figure, the output signal frequency is free from the influence of physical property and grouping variety, and its instrument factors only involve with figure and size of vortex generators. Thus, no compensation is needed when measuring volume traffic, while no instrument factors needed to be recalibrated when a part changed.
  • It's so widely used that it can measure steam and gas as well as liquid.

     HANDLING PRECAUTIO                             
    The LXW Series Vortex Flowmeter are thoroughly tested at the factory before shipment. When these instruments are delivered, perform a visual check to ascertain that no damage occurred during shipment. This section describes important cautions in handling these instruments. Read carefully before using them. If you have any problems or questions, contact your nearest
    GPE Inc. service center or sales representative.
    2.1 Precautions Regarding Transportation and Storage Location
    To protect against accidental damage to vortex flowmeter while transporting it to a new location, pack it in the original
    packing as when shipped from YINUO factory.
    WARNING!
    The Vortex Flowmeter is a heavy instrument. Please be careful to prevent persons from injuring when it is handled. Deterioration in insulation or corrosion can occur for unexpected reasons if vortex flowmeter is left uninstalled for a prolonged period after delivery. If vortex flowmeter is likely to be stored over a prolonged period, observe the following precautions.
    Store the vortex flowmeter with forwarded statement.
    Choose a storage location that satisfies the following requirements:
    • Not exposed to rain or splashwater.
    • Less susceptible to mechanical vibration or shock.
    • Kept within the temperature and humidity ranges shown in the following table, preferably at normal temperature and humidity (approximately 25°C, 65%)
    Temperature-25°C to +60°C
    Humidity5 to 95% (no condensation)
     
     
    2.2  Precautions Regarding Installation Locations
    (1) Ambient Temperature
    Avoid an area which has wide temperature variations.When the installation area is subjected to heat radiation from process plant, ensure adequate heat prevention or ventilation.
  • Atmospheric Conditions Avoid installing the vortex flowmeter in a corrosive atmosphere. When the vortex flowmeter must be installed in a corrosive atmosphere, adequate ventilation must be provided
    (3) Mechanical Shock or Vibration
    The vortex flowmeter is of sturdy construction, but elect an area subject to minimize mechanical vibration or impact shock. If the flowmeter is subject to vibrations, it is recommended that pipeline supports to be provided as shown in Figure 4.
