Vortex Flow Meter
(With And Without Temperature & Pressure Compensation )
MODEL: VFM250 Series
Flange vortex flow meter is used in numerous branches of industry to measure the volume flow of liquids, gases and steam. Applications in the chemicals and petrochemicals industries, for example, in power generation and heat-supply systems involve widely differing fluids: saturated steam, superheated steam, compressed air, nitrogen, liquefied gases, flue gases, carbon dioxide, fully demineralized water, solvents, heat-transfer oils, boiler feedwater, condensate, etc.

Advantages
Vortex flow meter advantages and disadvantages
Vortex flow meter body is robust and universally applicable for liquids, gases and steam,optimized for steam applications. CBRO Vortex flow meter adopt Japan OVAL technology and design. To protect the sensor, CBRO vortex flow meter choose embedded sensor, with 4 piezo-electric crystal encapsulated inside the sensor, which is our own patent. There is no moving parts, no abrasion, non-wearing parts inside the vortex flow meter sensor, fully welded SS304 body (SS316 selectable). With patented sensor and flow sensor body, CBRO vortex flow meter could eliminate drift & vibration influence from great aspect in the working site while compare with other flow meters.
Application
Vortex flow meter application
Vortex flow meter is professional in measuring non-conductive liquids, gases, saturated and superheated steam, especially for steam measurement trade settlement.
Except work as flow meter, vortex flow meter can also work as heat meter to measure the Gross/net heat of steam and hot water.
Vortex flow meter usually monitor the compressor output and evaluation of Free Air Delivery (FAD)
There has lots of Industrial gases, such as natural gas, nitrogen gas, liquefied gases, flue gases, carbon dioxide etc, all could use vortex flow meter.
In many factories, compressed air monitoring is very important, vortex flow meter also could use for process control. Besides the different gases measurement, vortex flow meter could also used for light oil or any purified water，such as thermal oils, Desalinated water, demineralized water, RO water, boiler feed water, condensate water etc.
In the Chemicals and petrochemicals industries, there also has lots of gases or liquid could use vortex flow meter for monitoring.

Installation
1. The installation of vortex flow meter has higher requirements, to guarantee the better accuracy and working properly. Vortex flow meter installation should keep away from the electric motors, big frequency converter, power cable, transformers, etc.
Do not install in the position where there has bends, valves, fittings, pumps etc, which could cause flow disturbances and influence the measurement.
The front straight pipe line and after straight pipe line should follow below suggestion.

2. Vortex Flow Meter Daily Maintenance
Regular cleaning: The probe is an important structure of the vortex flowmeter. If the detection hole of the probe is blocked, or is entangled or wrapped by other objects, it will affect the normal measurement, resulting in inaccurate results;
Moisture-proof treatment: most of the probes have not undergone moisture-proof treatment. If the use environment is relatively humid or is not dried after cleaning, the performance of the vortex flow meter will be affected to a certain extent, resulting in poor operation;
Minimize external interference: strictly check the grounding and shielding conditions of the flow meter to ensure the accuracy of the flow meter measurement;
Avoid vibration: There are some parts inside the vortex flowmeter. If strong vibration occurs, it will cause internal deformation or fracture. At the same time, avoid the inflow of corrosive liquid.
