Variable area flowmeter

high precision, good interchangeability, widely measuring range, variable connection type,installation

Feature:

1.  Superior safety performance,due to all the material of the component is metal part, so it can work safety in extremely diafusting condition.

2.  Install easily.The height is 250mm, convenient for designing.The upstream and downstream straight pipeline section requested to greater than 5D.

3.   Resistant to high temperature and high pressure.The maximum operating temperature can reach 300°C, the operating pressure can reach 4.0 MPa.

4.   Multiple output type.It can indicate the flow rate directly and output the standard current signal(compatible with HART protocol)to realize the functions of remote control, alarm.

5.  Little pressure loss.The measuring principle determined to low pressure loss, it suitable for measuring the flow rate in the condition with little operating pressure,  compared to other meter, it can conserve energy better.

6.   Superior economic performance.The main components can exchange each other, so it raise the price /performance .
