- Easy operation: Capable of operating a setting with front keypad and making a setting by PC.
- Communication function (option): Management of measurement data by PC through RS-485 (MODOBUS).
- Hardly affected by pressure and temperature of the measured fluid.

Ultrasonic Flowmeter by Fuji Electric is ideal for proper management for compressor.

- Abundant applicable pipe diameters.
Applicable pipe diameter 25mm up to 200mm.
- No energy loss due to no pressure loss.
Measurement principle is ultrasonic method. There is no pressure loss without protrusion in the pipe.
- No need of filter such as mist separator thanks to FWD has high resistance to oil mist.
Accurate flow rate measurement including oil mist. Strong durable and reliable to use.
- No need of power source installation work by means of battery driven.
Lithium-battery build-in type (approx. 10 years operating) is provided without painful wiring work of the power.
- NORMAL conversion function is provided as standard.
Converted amount of used air ,temperature and pressure into normal status are displayed.
- Capable of forward/reverse measurement and output.

Fuji Electric application examples.

Capable of detecting the air leakage.
When compressor is operated with closing valve, at the place where flow rate is measured air leakage occurres.


Connecting to Multi Measurement Unit allows visualization furthermore and saving energy.
Multi Measurement Unit (FeMIEL) is capable of monitoring a power consumption and fl ow rate simultaneously, additionally, communicating PC through Ethernet.
Multi Measurement Unit (FeMIEL): This unit is applicable to multi measurement using PT,CT, Pulse, Analog and Contact input. Build-in Memory can store one year volume of data (when every 5 min. measurement cycle) Compact size with front dimension 96 x 48mm.


Available to comprehend the used amount of air for each building, floor, line in the factory.
