The totaliser of the OMNI flow rate system enables a totalisation or measurement of consumption for all HONSBERG device families (for fluids and gases) with which the OMNI system is compatible; this is independent of the input signal, pulse or analogue input, and of the measurement process. Simple filling control is also possible. Here, the counter can be set to count upwards or downwards. When the preset point is reached, a switching signal is emitted which is available in antivalent form to two outputs. Resetting can be carried out by means of a signal input or also by a programming ring. The state of the counter is indicated in an LCD display with only four digits. Here, the number of decimal places and the unit displayed is continuously matched to the current state of the counter. In this case, the smallest value which can be displayed is 0.001 ml (= 1 μl), and the largest is 9999 mÑ. The counter therefore has 13 places, of which the four most significant are displayed at any one time. The display resolution at all times is therefore at least 1 per thousand of the displayed value, or better, and this generally exceeds the accuracy of the connected flow transmitter. The nondisplayed digits of the counter are in that case irrelevant to the accuracy of the measurement. The automatic dynamic changeover of units in the display in relation to the state of the counter makes the value easy to read in spite of a display with only four digits. In addition, user configuration of the counter is unnecessary. In addition to the totalised value, the present flow rate can be displayed.
