Engineering hints
Orientation
•
Recommended distance (1) wall –
outer
edge
of nozzle: ~ 1/6 of tank diameter.
•
Mount the Micropilot S at a position
where the tank movement due to filling/
emptying of the tank is of low influence.
•
Not in the centre (3), interference can
cause signal loss.
•
Not above the fill stream (4).
•
It is recommended to use a weather
protection cover (2) in order to protect
the transmitter from direct sun or rain.
Assembly and disassembly is simply
done by means of a tension clamp (see
»Accessories« on page 74).
Tank installations
•
Avoid any installations (1), like limit
switches, temperature sensors, etc.,
inside the signal beam (refer to beam
angle).
•
It is essential that HiHi alarm is below the
blocking distance (BD) and teh safety
distance (SD) (see page 15).
•
Symmetrical installations (2), e.g.
vacuum rings, heating coils, baffles,
etc., can also interfere with the
measurement.
Optimization options
•
Antenna size: the bigger the antenna,
the smaller the beam angle, the less
interference echoes.
•
Mapping: the measurement can be
optimized by means of electronic
suppression of interference echoes.
•
Antenna alignment: refer to "optimum
mounting position"
•
Stilling well: a stilling well can always be
used to avoid interference. The FMR 532
with planar antenna is recommended for
stilling wells with a diameter DN150 (6”)
and larger.
