Characteristics
The flow meter consists of a spinner which is rotated by the flowing
medium. The rotor's rotational speed is proportional to the flow
volume per unit time. The rotor is fitted with stainless steel clamps
(optionally titanium or Hastelloy®). An inductive proximity switch
records the rotational speed, which is proportional to the flow rate.
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 analog 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
0.00 ml (= µl), and the largest is 9999 m³. The counter therefore
has 3 places, of which the four most significant are displayed at
any one time. The display resolution at all times is therefore at least
per thousand of the displayed value, or better, and this generally
exceeds the accuracy of the connected flow transmitter. The
non-displayed 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.
The stainless steel case has a hardened non-scratch mineral glass
pane. It is operated by a programming ring fitted with a magnet, so
there is no need to open the operating controls housing, and its
leakproofness is permanently ensured.
By turning the ring to right or left, it is simple to modify the
parameters (e.g. switching point, hysteresis...). To protect from
unintended programming, it can be removed, turned through 80 °
and replaced, or completely removed, thus acting as a key.

Wiring
Before the electrical installation, it must be ensured that the supply
voltage corresponds to the data sheet.
The use of shielded cabling is recommended.

Handling and operation
Installation
The Rototron device is installed in the pipework with the aid of the
rotatable adapter pieces. If necessary, the adapters can be
removed from the body of the housing after the stainless steel clips
have been removed from the housing. Before reinstalling, it should
be ensured that both the adapter with the O-ring and the sealing
surface in the body are clean and undamaged. The adapters
should be fitted carefully in the housing (it is best to turn them), so
that the O-ring is not damaged.
With this flow sensor, there is no need for run-in and run-out
sections. However, it should be ensured that the flow sensor is at
all times filled with medium. Any preferred installation position is
possible, but the best possible venting position should be chosen
(rotor axis horizontal, flow horizontal or from bottom to top).
Air bubbles affect the measurement results. For filling processes,
the valve should be installed behind the sensor. A running up time
of approx. 0.5 seconds and a running down time of approx. 3
seconds should be noted.

A gooseneck (optional) between
the electronics head and the
primary sensor provides
freedom in the orientation of the
sensor. This option
simultaneously provides thermal
decoupling between the two
units.

Programming
On the display, the counter indicates the state of the totaliser as a
value and unit. The units ml, L, m3 are set automatically.
For operation as a totaliser, no configuration by the user is
necessary.
To use the other functions, configuration may be required. This is
carried out using the programming ring located on the device.
The annular gap of the programming ring can be turned to positions
and 2. The following actions are possible:
Set to 1 = continue (STEP)
Set to 2 = modify (PROG)
Neutral position between
1 and 2
The ring can be removed to act as a key, or turned through 80 °
and replaced to create a programming protector.
Operation is by dialog with the display messages, which makes its
use very simple.
The control display of the present flow rate depends on the
metering range of the selected flow transmitter, and has already
been set appropriately in the factory (ml/min, l/min, l/h, m3/h).
It is activated by turning the ring to position
After 0 seconds, the display automatically returns to the totaliser
mode.
For operation as a preset counter, the following must be set:
. The preset point
2. The type of output signal ("Preset has been reached"):
Signal edge / wiper pulse
width of the wiper pulse, if required
3. The unit of the preset point:
(ml, litre, m3).
Starting from the normal display (total and unit), if (STEP) is
selected repeatedly, then the counter shows the following
information:
●Normal display is total and unit (e.g. litre)
●Display of present value (e.g. l/min)
●Preset point incl. type of switching output.
●Code
The code gives access to various input levels into which
parameters can be entered (so that this does not occur
unintendedly, the code must be entered!)
Code 111:
●Gate time (available only for sensors which transmit frequency)
●Filter time
●Direction of count (pos. / neg.)
●Unit for switching value/reset point
●Decimal place for switching value/reset point
●Switching type for switching value (edge/wiper signal)
●Pulse duration (for wiper signal)
●Reset method (manual / via signal)
Code 100:
●Manual reset for totaliser
The detailed flow chart for operation is available in the "Operating
instructions for OMNI-C".
