Instrumentation
Integral Ultrasonic Flowmeter S-Flow <FSZ>

Easy Installation, Space Savings

Flow rate is “visualized” using our long-cultivated ultrasonic technologies.
Contributes to energy savings and production process solutions.

Easy Clamp-on type by simply tightening 4 screws.
No need for pipe modification.
Integrated detector and flow transmitter for space savings.
Built-in temperature sensor enables simultaneous measurement of flow rate and temperature (Optional).

Equipment configuration

Integrates the detector and flow transmitter to simplify equipment configurations.

Features

Measuring principle

Transit-time measuring method by Fuji proprietary digital signal processing
By using the ultrasonic pulses transmitted diagonally between the upstream and downstream sensors mounted on the outside of the pipe, the flow rate is measured by detecting the time difference obtained by the flow of fluid.

Reduces labor hours and installation costs

Clamp-on type requires no pipe modification. It can be installed without stopping equipment.

Easy installation using a single screwdriver.

Easy to set up

Configurable only with three buttons. Simply turn on, configure four settings, and start measuring immediately.

No grease required

Installation is easy and no longer requires the application of grease.
No need to store grease for maintenance purposes.

Easy-to-read LED display of flow rate values

Easy-to-read, intuitive 2-row LED display. Front function keys allow for easy operation.

Integral, Compact design

Flow transmitter and detector functions are integrated to achieve compact dimensions. Compared to conventional flow transmitter (type: FLR), the size is reduced by approximately 76%.

Can be installed on densely-spaced piping and inside of equipment

Comes standard with RS-485 communication

RS-485 communication makes it possible to simultaneously output the instantaneous flow rate, integrated flow rate, temperature, and other data. Parameters can also be set using the loader software.

* To connect to a PC, an RS-485/RS-232C or USB converter is required.
