Type YF100 Vortex Flow Meter

Time：2018-05-24 17:22 Author：freededecms.com Click:次

 

Series of vortices will be shed alternatively from both sides of the shedder (that is a cylindrical or triangular bar) when it is inserted in the fluids. Under certain conditions, the frequency of shed vortices should be proportional to volume flow rate. Based on this principle, the flow measurement could be carried out through measuring frequency of vortices by means of vortex flow-meters. 
Two versions are available: one has a built-in (integral) converter, and the other is used with a remote converter.

Features：
● Wide application—liquids, gases and steam can all be measured;
● High accuracy and wide flow range;
● Simple structure does not contain any moving parts, and its measuring sensor can not come into contact with fluid. This feature ensures high reliability and easy maintenance;
·

Different Displays at user’s option for different functions:
●Type TBS: Field Instant Flow Rate (5-digit LCD) and Totalized Flow (7-digit LCD)
●Type TBT: Field Totalized Flow (6-digit LCD)
●Type TBL: Field indicating of Instant Flow Rate in Percentage by pointer

Main Technical Specifications

Fluids to be measured Liquid, gas or steam
Measurable range Reynolds Number within 5×10^3 to 7×10^6
Normal Operating Range Reynolds number within 2×10^4 to 7×10^6(for nominal sizes 25A to 100A)
                                             4×10^4 to 7×10^6 (for nominal sizes 150A、200A)

Note: In addition to Reynolds Number, there should be a limit for fluid velocity during measurement; the maximum velocity for liquid is 10m/s, while maximum velocity for gas or steam is 80m/s; besides, minimum velocity is related to density and viscosity of fluids (see “Sizing” section).

Maximum Permissible Errors（within normal operating range）

Vortex Flow Meter Installation Description and Indicating

 

Description
Indicating
Pipeline Support :

Install the flow meter in the place with less vibrationIn case of big vibration, pipe support is needed;
 
Installation Direction:

If pipeline is always fully filled with liquid, pipeline maybe vertically installed, or installed at any angle-directions;
 
Adjacent Pipeline:

Inner diameter of adjacent pipeline must be slightly bigger than Inner diameter of YF100 Flow Meter;
Use the adjacent pipeline as below:
25-50mm flow meter: JISSch40(GB G60) and below80-200mm flow meter: JISSch80 (GB G100) and below
 

Reducing pipe:

For reducing pipe, to secure straight segment pipe length, at least 5D for its up-stream and 5D for down-stream;
(D: inner diameter of YF100 flow Meter)

Expanding Pipe:

For expanding pipe, to secure straight segment pipe length, at least 10D for its up-stream and 5D for down-stream;

Bending Pipe:

For bending pipe, to secure straight segment pipe length, at least 10D for its up-stream and 5D for down-stream;
Valve location and Straight segment pipe length:

Valves should be located at flow meter down-stream.Up-stream straight segment length depending on up-stream pipeline conditions
(like expanding pipe,reducing pipe, bending pipe etc, see above; and at least, 5D for down-stream)
If up-stream valve is necessary, to secure the up-stream straight segment pipe Length at least 20D above, 5D for down-stream
Pulsing fluctuation flow effect:

If Piston or Roots Air Blower or Compressor is used in gas pipeline, or, Piston or cylinder pump is used in high pressure liquid pipeline, fluid may vibrate;Valve is usually arranged at flow meter down stream; if being located in up-stream is unavoidable, to arrange an Attenuator at flow meter up-stream, such as orifice plate or expansion chamber etc.
Piston or Cylinder Pump：

To Arrange an energy reservoir at flow meter up-stream to minimize liquid Vibration
 


Description
Indicating
Valve location (pulsing pressure fluctuation caused by T-shape pipe) :

If T-shape pipe is used, to arrange a valve at flow meter up-stream
can avoid pulsing pressure influence; example as shown on the right,
when valve is being closed, fluid is flowing in direction B, no flow
passing through flow meter; however, pulsing pressure is still being
detected, meter zero point is fluctuating; change the valve location to V1’ to avoid what happens
Pressure measuring hole & Temperature measuring hole:

If pressure measuring is needed, pressure measuring hole shall be arranged at flow meter down-stream about 3.5D to 5.5D
If temperature measuring is needed, temperature measuring hole shall be arranged at pressure measuring point down-stream about 1D to 2D;
Gasket:
Do not let the Gasket protrude beyond inner pipe, otherwise measuring error occurs; even for clamping-style flow meter , gasket with bolt hole should be used;
If helix gasket (without bolt hole) is used; it needs to be tailor-made by gasket supplier; because standard ones do not fit some flanges.
Thermal Insulation:

Pipes on which assembly-style flow meter or separation-style flow sensor are installed for high temperature fluid transfer must be packed with thermal insulation materials; Never pack the convertor support with thermal insulating materials
Pipeline cleaning

Before operation, new pipeline or after-maintenance-pipeline need cleaning; wash out rust, sediment, residues and dirt;
During washing, water should be by-passed through by-pass pipe so to prevent flow meter from being damaged;
if by-pass pipe is unavailable, using a short pipe instead of flow meter
