4 Application 4 Application The S418-V is a Compact Thermal Mass Flow Meter that is designed to measure the actual flow at the low pressure side of vacuum pumps within the permissible operating parameters (in chapter 6 Technical data). The S418-V can measure the following values: Absolute volumetric flow (default unit: al/min) •...

Remark: The total consumption value is saved to the permanent memory every 5 minutes. If within these 5 minutes the device is powered off, it will restore the last consumption value which was saved in the last cycle. 7 Dimensional drawing Unit : DN8/DN15 S418-V...
The flow sensor is equipped with two connectors “A” and “B”. By default the sensor is delivered with one 5 m cable with a M8 connector on one side and open wires on the other side. To make the S418-V work, one S418-V...

9 Sensor signal outputs 9.3.2 Connect Several S418-V to Modbus Master The S418-V with Modbus/RTU interface can be easily daisy-chained to a Modbus Master device. This master can be either SUTO displays and gateways or any third-party Modbus/RTU master. Through this method you can add up to 16 flow meters to the master device.
See the below picture for details. 9.3.2.3 Create Daisy-Chain using RS-485 Splitter To connect the S418-V to the daisy-chain, the RS-485 splitter (A554 3310) and the M8 to M12 converter cable (A553 0161) are needed. Furthermore place a M12 termination resistor (C219 0055) at the last splitter in the daisy-chain, as show in the figure below.
Other connection topologies are not recommended and should be avoided. Make sure that at the end of the bus line, the termination resistor of 120 Ohm is placed to avoid interferences. Recommended connection of Modbus/RTU salves in a daisy-chain Topology. S418-V...

10 Configuration 10 Configuration To change any settings on the S418-V, download and install the service App S4C-FS from the Google Play store or SUTO Website. This App works on any Android or iOS system with Bluetooth supported. To be allowed to change settings, the App needs to scan the QR code on the calibration certificate.
11.2 Operations 11.2.1 Logger configuration You can control and configure the S418-V data logger using the S4C-FS App. Detailed steps are as follows. 1. Install and launch the S4C-FS App. For more information, see the S4C-FS Instruction and Operation Manual.
