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.
