5 Function description
5.1 Functional principle
5.1.1 Usage
The electronic unit is designed for use with a KRAL flow meter.
Flow meters generate a specific number of pulses per flow volume unit –depending on the size and
working point. This device-specific characteristic is called the K factor (unit: pulses/litre) and is spe-
cified on the calibration certificate.
The pulse signals from a flow meter can be evaluated. Due to the pull-down resistor at the signal input,
the following signals are available:
oPNP / push-pull / active signals
oNamur
5.1.2 Volume measurement
The instantaneous value of the flow rate is calculated and displayed by measuring the time between a
series of pulses and the stored K-factor. In addition, the total number of measured pulses can be used
to display the total flow (volume) as a total value since the last reset of the unit. Values for the flow rate
represent the current instantaneous values, total values correspond to the totals since the last reset.
5.1.3 Electronic evaluation
The electronic unit receives signals from the pick up and calculates the measurements, which are
shown in the display and can be called up at the pulse output.
Electronic unit options:
oDisplay the measured volume in different units (l, m³, kg, lb, gal, galUS, bbl)
oFault information
o1 scalable pulse output (non-isolated transistor)
o1 scalable analogue output
5.1.4 Applications
The electronic unit is intended for use in a single-line measurement in combination with a flow meter.

Note If the operating conditions require it, the minimum and maximum value of the output signal can be ad-
justed. However, an adjustment may only be made if the analogue output is deactivated.
Changing the values when the analogue output is activated can produce undesired measurement res-
ults and consequently damage to the unit.

13 Maintenance
13.1 Required maintenance
When operating under approved conditions, the electronic unit is maintenance-free.
1. Check the condition of the housing and cables at regular intervals.
2. Periodically check the input/output wiring for reliability and signs of wear.
3. Periodically check process accuracy. It may be necessary to recalibrate the flow meter as a result
of wear and tear. If this results in a change in the K-factor, it must be entered again.
Note If the relative humidity exceeds 90%, a bag of silica gel in the housing of the electronic unit is recom-
mended.
13.2 Cleaning the electronic unit
ATTENTION
Device damage through water.
► Ensure that no water enters the electronic unit.
Wipe the housing with a soft cloth. In the case of strong soiling wipe off the housing surface
slightly moist with a common detergent.
14 Disposal
14.1 Disposing of the electronic unit
ATTENTION
Environmental damage through improper disposal.
► Dispose of all the components in an environmentally friendly manner in accordance with the applic-
able local regulations.
As electronic waste the electronic unit has to be disposed of properly.
