Vortex Flow meter 
Vortex flow meter is based on Carmen (Karman) vortex principle???it can measure the gas, steam

or volume flow rate of the liquid, volume flow of standard conditions or mass flow .Also it can be applied as a flow transmitter for automation and control systems.

Karman principle :f =St*V/d

Scope:

Gas: air, compressed air, oxygen, carbon dioxide, nitrogen gas, natural gas, methane gas, ammonia gas etc. Steam: superheated steam, saturated steam.
Liquid: water, oil

Application:

Vortex flow meters are widely used in large, medium and small variety of pipes ,for drainage, industrial recycling, sewage treatment, oil and chemical reagents .As well as measuring compressed air, saturated and superheated steam metering,natural gas.

Second.Features

??? With moving parts, simple structure, easy for installation maintenance
??? The frequency and the actual measured fluid flow is linear, zero drift, the performance is very stable.

The  gas meter is a high precision instrument for gas volume
measurement and flow measurement of natural gas and other non-aggressive gases in gas stations and plants. The  rotary gas meter is applicable in residential and office buildings as well as commercial and industrial plants.

 

FEATURES

  • Meter sizes G10 to G1000.
  • Flow rates from 0.5 to 1600 m3/h.
  • Nominal sizes from DN25 to DN200. 
  • Temperature range -25°C to +55°C. 
  • Pressure ratings PN10/16 and ANSI Class 150.
  • Measuring range standard 1 :50 (G25 1 :80) , optional up to 1 :200.
  • Anodized high strength aluminum meter housing 
  • Synthetic material Index head, optional Aluminum index head.
  • Rotating counter (355°). 
  • No inlet or outlet straight pipe required. 
  • Horizontal and vertical mounting position.

Description and operation

The  rotary gas meter registers the operating volume using an eight-digit mechanical counter. Via pulses the operating volume can be transferred to an electronic volume corrector and converted to normal or standard conditions.The TYL rotary meter is approved for custody transfer according to MID (2004/22/EC) I OIML.

 

Rotary gas meters are operating according the displacement principle. In the meter housing are two 8-shaped coordinated rotating pistons without touching each other. The measuring chamber is regularly filled and emptied by the rotation. During each revolution four crescent-shaped volumes are moved through the measuring chamber, in which the rotation speed is proportional to the gas flow. The rotation of the pistons is synchronized by a gear train outside the measuring chamber (*Exception is DN 100)

 

The actual volume flow can be transmitted to electronic volume correctors or data loggers via low frequency (LF-) pulses generated by Reed contacts. In the meter''s index head is also located an anti-tampering contact.

 

Rotary gas meters are characterized by a very compact design and high accuracy. The  rotary meter requires no inlet or outlet pipe and is insensitive to severe gas flow fluctuations (discontinuous operation).

Introduction

Mass Flowmeter is designed according to the Coriolis Principle. It can be widely used for the process detecting and custody transfer/fiscal unit in many industries such as petroleum, petroleum and chemical, chemical industry, pharmacy, paper making, food and energy, and so on. As a fairly advanced kind of flow measurement instrument, it has been paid attention by the circle of measurement and accepted by many customers home and abroad.

1.2 Principle

Mass Flowmeter is designed according to the principle of Coriolis force. Under the alternating current effect, the magnet and coil installed on the measuring tube will make two parallel measuring tubes vibrate according to some fixed frequency. Once there is flow passing through the pipes, Coriolis force will give rise to deflection (phase shift) on the vibration of two pipes and the deflection of vibration is directly proportional to the mass flow of fluid. Pick up them and the mass flowrate could be calculated.

The vibration frequency of measuring tube is determined by the total mass of measuring tube and inner fluid. When the fluid density changes, the vibration frequency of measuring tube will be also changing, as a result, the fluid density can be calculated.
The temperature sensor installed in the pipeline can pick up the fluid temperature on time under the coordination of measuring circuit.
