6. Installation 6. Installation Before you install the sensor, make sure that all components listed below are included in your package. Qty Description Item No. 1 S430 Sensor S695 4300/S695 4302 1 Sealing ring No P/N 1 Alignment key No P/N 2 M12 plug C219 0059 1 Instruction manual No P/N 1 Calibration certificate No P/N 6.1 Installation Requirements To install the sensor a ball valve or a nozzle is needed. • The inner thread has to be G 1/2”.
6. Installation ATTENTION! Wrong measurement is possible, if the sensor is not installed correctly. • Careful attention must be paid to the design of the inlet and outlet section. Obstructions can cause counter-flow turbulence as well as turbulence in the direction of the flow. • The sensor is for indoor use only! At an outdoor installation, the sensor must be protected from solar radiation and rain. 6.2.
6. Installation 6.2.2 Insertion angles Please install the sensor only in the recommended area like you can see in the picture. A horizontal installation is not permitted. Please consider that the distance to the horizontal level must be >10°. Installation in a vertical pipe is possible, required the flow is from bottom up and the sensor has at least a 10 degree angle (recommended is 20 degree). ATTENTION: Do not install in vertical pipes if the flow is from top to down.
6.3 Calculating the insertion depth Generally, the sensor tip must be placed in the centre of the pipe. To facilitate this, the sensor is designed with a scale engraved on its shaft. To determine the right position, calculate the insertion depth as described below. Note: If the pipe diameter is greater than the shaft length, it is feasible to install the sensor out of centre of the pipe. For more information, please contact the manufacturer. 6.3.
6.3.2 Non-centre installation In bigger pipe diameter (> DN150) situations, the non-centre installation is applicable. In the non-centre installation, the sensor is inserted to exact 100 mm-depth of pipes.
6.4 Installation of the sensor First please observe the flow direction indicated on the housing or on the shaft. It must match the flow direction of the compressed air or gas. 1. Ball valve has to be closed. 2. The sensor head has to be completely covered by the connection thread (see photo on the left). 3. Underlay the “O-ring” at the thread of the ball valve before screwing the flow sensor. 4. Screw the connection thread tightly to the ball valve and align flow sensor to flow direction. 5.
Maximum angle deviation of a proper installation: 6.5 Performing the zero flow calibration The zero flow calibration is a compulsory operation during the installation of the sensor. Use one of the following methods to perform the calibration: • The service App S4C-FS, available on the Google Play store or our Website for free download • The optional local display 6.5.
Sensors that are within the reach of your Bluetooth signal while not connected with other S4C-FS Apps are displayed on the home screen. Note: A red Wireless Connection icon is displayed behind a connected sensor, which indicates that the sensor is successfullyconnected but accessible in the read-only mode. In this mode, you can only view the online parameter values and existing settings. 4. Click the Scan QR Code button, and then scan the QR code provided on the calibration certification.
6.5.3 Using the local display See steps 4 and 5 described in the following Figure 3. Figure 2: Steps to expose the sensor to the system pressure Figure 3: Steps to perform the zero flow calibration 6.
4. Close the ball valve. 5. Unscrew the connection head and pull the flow sensor out of the ball valve. 6.7 Making electrical connection The flow sensor is equipped with two connector plugs “A” and “B”. The cables are connected to the sensor through the M12 connector.

7. Configuration • • Installation FAD: Free Air Delivery calculated based on the total measured volumetric flow at programmed intake conditions (for example, 25°C, 980 hPa, 30 %rH) Working Condition Flow: Working volumetric Flow at fluid pressure and temperature. Select an installation method • Center Installation • 100mm insertion depth 7.1.2 Unit settings Configure units for flow, pressure, temperature, and consumption. 7.1.
7. Configuration 7.2 Configuration using the service App S4C-FS This is the most convenient way especially when the sensor is not equipped with the optional local display. The App is available for Android systems. You can download the service App from the Google Play store or our Website. To change settings using the App, you must scan the QR code on the calibration certificate. This ensures that only valid users can change the sensor settings.
7. Configuration 7.3 Configuration using the optional sensor display With the Sensor display it is possible to show the value of the velocity, the flow and the consumption. Moreover it shows error messages and it is possible to change the configuration setting of the sensor. "Enter key” = “Up key” = "Down key” = 7.3.1 Starting process After power up, the display starts automatically with a initialisation procedure.
7. Configuration Icons are shown in the status bar indicating status or warnings for the sensor in service. The following table provides descriptions for these icons. Icon Description Calibration expired Temperature over operating range Flows over measuring range Pressure over operating range Pressure sensor damaged Temperature sensor damaged Flow direction 7.3.3 Configuration instructions 1. Press the Enter key (>3s). 2. Enter the unlock code:12 using the Up and Down keys, and then enter Enter key. 3.
7. Configuration 8. Sensor signal outputs 8.1 Analog output The sensor has an analogue output range of 4...20 mA. This output can be scaled to match a desired measuring range. Standard is the range from 0 to max. flow depending on the pipe diameter. The corresponding flow in different pipe sizes can be found in the Appendix section. For other ranges, please contact the manufacturer. 8.2 Pulse output The sensor will send out one pulse per consumption unit.
8. Sensor signal outputs In case the flow rate is higher than 50 m3/s, l/s of ft3/s, the S430 can not output the pulses with default settings (one pulse per consumption unit). For this the pulse can be set by our service software or a connected display to 1 pulse per 10 consumption units or 1 pulse per 100 consumption units. For example, if set to 1 pulse per 10 m3, the sensor will send one pulse each 10 m3. Example: S430 Volume flow [m3/h] Pulse length [ms] Max.

9. Calibration 9. Calibration The sensor is calibrated ex work. The exact calibration date is printed on the certificate which is supplied together with the sensor. The accuracy of the sensor is regulated by the on site conditions, parameters like oil, high humidity or other impurities can affect the calibration and furthermore the accuracy. However we recommend to calibrate the instrument at least once per year. The calibration is excluded from the instruments warranty.
12. Warranty The warranty is cancelled: • If the user opens the measurement instrument without a direct request written in this instruction manual. • If repairs or modifications are undertaken by third parties or unauthorised persons. • If the serial number has been changed, damaged or removed. Other claims, especially those for damage occurring outside the instrument are not included unless responsibility is legally binding. Warranty repairs do not extend the period of warranty.
