Ultrasonic Flow meter S-Flow

This flowmeter is a clamp-on type ultrasonic flowmeter that can measure the volumetric flow rate of liquid inside a pipe by clamping on from the outside. By making full use of the latest electronic and digital signal processing technologies, this ultrasonic flowmeter is significantly smaller than conventional products. It integrates the flow transmitter and detector, enabling it to eliminate the need for signal cable wiring while facilitating mounting to pipes by adopting a greaseless design.

Easily deployable ultrasonic flow meter S-Flow

Easy installation, space savings.

Carbon neutrality on a global scale has been attracting attention in recent years.
Companies are promoting their activities to achieve high efficiency and energy savings.
Against this backdrop, more demand is growing to control the flow rate of fluid at the end points of the production lines in the factories. Fuji Electric has developed the easy-deployable Integral Flowmeter, named “S-FLOW” to support such demand. It has realized easy installation, space savings and affordable cost.
