Insertion type Vortex Flow Meter

Vertex Flow Meter, Flow Meter, Insertion Flow Meter
The vortex flow meter is widely used in petroleum, chemical, metallurgy, machinery, food, papermaking, and urban pipeline heating supply, water supply, and gas supply industries. It is designed to service the single-phase fluid of low viscosity liquid, gas and steam to process flow measurement and energy saving management.  

The insertion type vortex flow meter is divided into 2 types: simplified insertion type and ball valve insertion type.

Application Scope
1. Compared to a flange connection type vortex flow meter, the insertion type is only applied to pipe size DN150 or above.
2. It can output 4-20mA to a secondary instrument or other intelligent modules, such as DCS and PLC.
3. The flow meter can also output a pulse and is equipped with a flow totalizer for remote monitoring
4. This insertion vortex flow meter can communicate with a computer or other control systems under RS485 or HART protocol
5. Battery-powered or External-powered

To select the suitable model and ensure that the flow meter will work properly, we generally need to know the following information
1. Fluid / medium
2. Pipe size
3. Flow range
4. Temperature
5. Operation pressure
6. If a ball valve is required.

This information is extremely important, especially in steam application environments.
