votex flow meter with temperature and pressure compensation is one of the main flow instruments,which is widely used in the industry of petroleum, chemical, metallurgy and heat supply,etc.It can measure and calculate the flow of liquids, gases and steams.
1. It won't touch the fluids when testing the component. It is of high reliability and of
strong adaptability to all kinds of mediums.
2. It has no movable accessories. It can stand wear and tear. Its structure is firm and simple.
3. It has good anti-seismic property.
4. It has wide range of the working temperature, which is -40oC ~ +350oC.
5. It has wide range of measurement. It has high accuracy.
6. Output the pulse signal or two- wire system 4 ~ 20mA current signal.

4.Before the quotation, we need to know the following information:
Liquid, gas or steam?
2.Connection size( Caliber of pipeline), flow rate;
We should to confirm if the specific caliber can meet the request of flow-rate.
Caliber can be DN 25, 40, 50, 65, 80, 100, 125, 150, 200, 250,300 mm...
3.Temperature and pressure;
Do you need temp./pressure compensation or not;
4. Accuracy request;
This will affect the unit price.
6. With display or not.
