AVPP Flanged Type

●  The piped type classic venturi flowmeter is designed and manufactured according to ISO5167/GB2624, with flange connection for easy installation and maintenance on site.

●  International standard design, easy to calibrate and calculate.

●  Flange connection, easy installation and maintenance.

●  Permanent pressure loss is small.

AVFW Welded Type

●  The venturi flow meter and the process pipe are welded, the installation will prevent leakage.

●  Pipe welded, save installation materials.

●  Save the weight of the flow meter itself.
