Page 12: Short Example For Changing Parameter Value
Short example for changing parameter value It is necassary for you to change the value of temperature for 20 mA. Follow the short instruction below: Press simultaniously both PROG-keys. If flow computer has a password, you have to set ID-no.. Programm „2552“. -
Page 13: K-Factor - Menu Point K-Factor (Level D/7)
k-Factor – Menu point k-factor (level D/7) By using an avereraging pitot tube, the k-factor of the dp-sensor can be taken from the differential pressure calculation sheet. For unknown k-factors the value can be calculated by using the following equation. ·... -
Page 14: Protocol
Protocol Due to the low absolute transfer rates it should not come to any conflict in the communication between µFLOW and PC. Therefore a protocol is actually unnecessary. Nevertheless the transmission activity of the µFLOW can be controlled by transmitting XOFF by the PC and be continued with XON afterwards again for all cases. -
