Sensor signal outputs 8.2 Pulse output The sensor will send out one pulse per consumption unit. This pulse output can be connected to an external pulse counter to count the total consumption. The number of m3 per second are summed up and indicated after one second. Pulse length depends on flow rate. Volumetric flow [m3/s] Volumetric flow [m3/h] Pulse length [ms] Max.

Configuration 9 Configuration Please download the service app from the Google Play Store in case you need to have any settings changed on the S 415. The app is running on any Android system with Bluetooth supported. To change settings the app needs to scan the QR code on the calibration certificate at first. This ensures that only valid users can access the sensor settings. Follow the instructions in the service app.
Calibration 10 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.
Warranty The warranty is canceled: • 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 unauthorized 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.

Appendix C - LRC and CRC calculation 15 Appendix C - LRC and CRC calculation LRC generation The Longitudinal Redundancy Checking (LRC) field is one byte, containing an 8–bit binary value. The LRC value is calculated by the transmitting device, which appends the LRC to the message. The device that receives recalculates an LRC during receipt of the message, and compares the calculated value to the actual value it received in the LRC field. If the two values are not equal, an error results.
Appendix C - LRC and CRC calculation LRC generation function static unsigned char LRC(unsigned char *auchMsg, unsigned short usDataLen) { unsigned char uchLRC = 0 ; while (usDataLen––) uchLRC += *auchMsg++ ; /* LRC char initialized */ /* pass through message buffer */ /* add buffer byte without carry */ return ((unsigned char)(–((char)uchLRC))) ; /* return twos complement */ } CRC generation The Cyclical Redundancy Checking (CRC) field is two bytes, containing a 16-bit binary value.
Appendix C - LRC and CRC calculation 8. When the CRC is placed into the message, its upper and lower bytes must be swapped as described below. Placing the CRC into the message When the 16-bit CRC (two 8-bit bytes) is transmitted in the message, the low-order byte will be transmitted first, followed by the high-order byte.
