5.4 (8) Low flow output cut

Description

A low flow output can be cut.
This flowmeter will display the flow rate, when the fluid in the piping is moving with the
valve closed due to a convection current.  The cutting point should be set as needed.
(Setting range : 0 to 16.4 ft./s in terms of flow velocity value)

Operation (example) Setting of cutting point to 0.05m/s.
