Kseof use 2 Effectively Utilize Degital Communications All models have communications functions for loT compatibility. RS-485(CPL)/ Modbus™ RTU Ease of use With isolation of the power supply from the signal circuit, power supply noise can’t affect analog signals. Additionally, highly noise-resistant 4 to 20 mA signals can be used. ^!seof use ■P Reduction in Overall Cost Overall cost is lower for reasons such as: communication functions eliminate the...

Compact Design Saves Space I The new products are 50 % smaller than our With a width of 28 mm, the product’s slim design conventional models. allows closer spacing of pipes, saving more space. Effectively Utilize Degital Communications RS-485 (CPL)/ Modbus™ RTU Analog mass flow controllers With model F4H's communication functions, much information can communicate only flow rate useful for fault diagnosis can be uploaded. Also, with a smart device to programmable logic controllers. gateway (model NX-SVG), the F4H can communicate with major programmable logic controllers without the need for...

High Noise Tolerance ® Isolation of the power supply from the signal circuit By isolating the valve drive circuit from other circuits, power supply circuit and analog circuit isolation (patent No. 5132617) is achieved, even with a small-capacity isolated power supply. Thanks to this feature, noise from power wiring has no effect on signals. © Highly noise-tolerant 4-20 mA signals can be used. Choose analog I/O signals from 0 to 5 Vdc, 1 to 5 Vdc, 4 to 20 mA. (D All models have digital communication capability Using to digital communication eliminates the effect of noise on analog signals....

*9. During EMC testing, the reading may fluctuate by the equivalent of ±5 % FS, or the output value may fluctuate. *10. For F4H0020, C-36 (operating differential pressure) is set to “0: Low differential pressure.” *11. Use within a power supply voltage range between 23.5 and 25.2 V. *12. The maximum operating differential pressure varies according to the power supply voltage. See the following graph. The operating differential pressure range for argon is from 250 to 300 kPa. *1. mL/min and L/min are volumetric flow rate per minute (L/min) converted to conditions of 0 °C and 101.325 kPa (1...

> Cautions for Flow Controllers (For installation and use of this device, refer to the warnings and cautions in the user’s manual.) - Never allow gases that are within explosive limits to pass through this device. Doing so might result in an explosion. - Never use a flow controller for oxygen gas if it is not a special oil-free oxygen gas model. Doing so could cause the gas to ignite. - Prevent foreign matter from entering the device. Rust, water droplets, oil mist, or dust from the pipes can cause measurement error, control error, or damage to the device. If there is a possibility of...
