มิเตอร์วัดอัตราการไหล Flow Meter
รุ่น GTF Series
คุณลักษณะ
A complete VA flowmeter consists of a glass flow tube and float scaled to the flow units required, and a frame to provide the end block supports and to cover and protect the tube. The NGX series frames use flow tubes with nominally 100mm long scales, whereas the smaller LGX frames use flow tubes with nominally 30mm scales. To choose a complete flowmeter select the frame code required, and separately specify the fluid flow range needed on the flow tube scale. NGX and LGX series frames are designed to fit your process. The options available allow easy installation, usually surface mounted on a vertical panel. Process connections and labelling can be customised to suit the application.
