  • Page 17 Page 17 K-FACTOR A With the Total K-Factor, the flowmeter pulse signals from pickup A are converted to a total unit. The Total K-Factor is based on the number of pulses generated by the flowmeter per selected measurement unit (SETUP 1.1).. The more accurate the Total K-Factor, the more accurate the functioning of the system will be.

  • Page 20 Page 20 LCD NEW The calculation of the display-information influences the power consumption significantly. When the application does not require a fast display refresh rate, it is strongly advised to select a slow refresh rate. Please understand that NO information will be lost; every pulse will be counted and output signals are generated in the normal way.
  • Page 21 Page 21 The automatic unit conversion can handle either volume or mass units. For measurement units which are not supported, for example ‘revolutions’ or the use of volume and mass units simultaneously, the automatic unit conversion can be set to ‘Hand’, allowing total and flowrate to be configured independently.
  • Page 22 Page 22 CALCULATE If bi-directional measurement is enabled (SETUP 6.3), select here the way of calculation: Add: Forward flow will be interpreted as positive flow. Differential Total, accumulated Total will count up. Accumulated Total A will count up (if enabled at SETUP 5.2 Reverse flow will be interpreted as positive flow.
  • Page 23 Page 23 3.3.8 EXPLANATION OF SETUP-MENU 7 - ANALOG OUTPUT An analog 4-20mA signal is generated according to the flowrate with a 12 bits resolution. The settings for Flowrate (SETUP-menu 2) influence the analog output directly and should be configured first.
  • Page 24 Page 24 TUNE MAX (20mA) The initial maximum analog output value is 20mA. However, this value might differ slightly due to ambient influences such as temperature for example. The 20mA value can be tuned precisely with this setting. Before tuning the signal, be sure that the analog signal is not being used for any application! After pressing PROG, the current will be about 20mA.

The screen of the signal wire must be connected to the common ground terminal (unless earthed at the sensor itself).
  • Page 38 Page 38 Pulse-signal NPN / NPN-LP The E115-P is suitable for use with flowmeters which have a NPN output signal. For reliable pulse detection, the signal should be above 1.4V or below 1.0V under all circumstances. It is advised to use a sensor which is normally open and is closed for a small time (less power consumption).
  • Page 39 Page 39 Reed-switch The E115-P is suitable for use with flowmeters which have a reed-switch. To avoid pulse bounce from the reed-switch, it is advised to select REED LP – low-pass noise filter, which limits the maximum input frequency (see paragraph 3.3.7 for more information). Make sure the contact resistance of the reed switch is less than 1V@2uA=500k Ohm.
  • Page 40 Page 40 Active signals 8.2V and 24V The E115-P is suitable for flowmeters with an Active signal. The detection levels are about 50% of the selected supply voltage; approximately 4V (ACT_8.1) or 12V (ACT_24). See paragraph 3.3.7 for more information. Active signal selection may be desired in the case of power supply type PD being supplied for sensor supply.
