This measuring instrument is a clamp-on ultrasonic flowmeter that can measure the volumetric flow rate of a liquid inside a pipe by attaching it from the outside. By making full use of the latest electronic and digital signal processing technologies, this ultrasonic flowmeter is considerably more compact than conventional flowmeters. It integrates the transmitter and flow sensor, eliminating the need for signal cable wiring, while its grease-free design facilitates mounting on pipes.
Flow is "visualized" using Fuji Electric's long-established ultrasonic flow measurement technologies.
Contributes to energy savings and production process solutions.
Global carbon neutrality has been attracting attention for some years now.
Companies are encouraging their activities to achieve high levels of efficiency and energy savings. In this context, there is a growing demand to control fluid flow at the end points of production lines in factories. Fuji Electric has developed an easy-to-deploy integrated flowmeter called "S-FLOW" to meet this demand. It is easy to install, space-saving and affordable.
HIGH PRECISION
EASY TO USE
COMPACT AND LIGHTWEIGHT
RESISTANT
Using ultrasonic pulses transmitted diagonally between upstream and downstream transducers mounted on the outside of the pipe, flow is measured by detecting the time difference obtained by the fluid flow.

Flow transmitter and sensor functions are integrated to achieve compact dimensions.
Compared with a conventional flow transmitter (such as the M-Flow FLR ultrasonic flowmeter), size is reduced by around 76%.
Its compact design means it can be installed in places where space is limited, such as in densely spaced pipelines and inside equipment.
An integrated temperature measurement function allows simultaneous measurement of flow and temperature.
In addition to piping for pure water manufacturing processes, cleaning processes and equipment cooling, it can also be mounted inside equipment where there is widely spaced small-diameter piping.
The flowmeter can be installed on cold and hot water pipes throughout the building. By measuring flow, it enables more efficient operation of fan coil units (FCUs). Similarly, it facilitates the efficient operation of air handling units (AHUs) for large spaces. Flow monitoring contributes to energy savings in industrial utilities.
Types and configurations
The S-Flow flowmeter is available in several types depending on the pipe diameter:
Each main unit is configured with an integrated transmitter and flow sensor.
Mounting and measuring method
Using a clamp-on mounting method, the ultrasonic flowmeter offers convenient installation without process interruption. The transit time measurement method guarantees optimum accuracy for homogeneous fluids, where ultrasonic signals can be transmitted efficiently.
Measuring range and accuracy
With a measurement range from 0 to ±5 m/s (minimum 0 to ±0.2 m/s), it guarantees exceptional adaptability. Accuracy is also outstanding:
Pipe materials and thicknesses
The flowmeter is compatible with a variety of pipe materials, including metals (stainless steel, steel, copper) and plastics (PVC, PP, PVDF). Pipe thickness can vary from 1.2 mm to 4.9 mm, ensuring maximum flexibility.
Environmental conditions
The FSZ flowmeter is designed to operate under a wide range of environmental conditions:
Display, Outputs and Options
The flowmeter features a 4-digit 2-line LED display for easy monitoring. Output signals include 4 to 20 mA DC (1-point) and contact (2-point). A pipe surface temperature measurement option is also available.
Power supply and weight
With a power supply of 20 to 27.5 V DC and a power consumption of 2.5 W or less, the S-Flow flowmeter is energy-efficient. Weights vary according to model: FSZ08 (400g), FSZ15 (500g), FSZ25 (600g), FSZ40 (800g).
