The new T/LL200 Sender from Fozmula (top left) is for use in tanks needing continuous
level measurement. The company also recently unveiled its improved T/LL171 range of level
senders (bottom right).
BY IAN CAMERON F ozmula has made two additional enhancements to its liquid level sensors range. The company,
based in Leamington Spa, England,
recently unveiled its expanded portfolio
of level senders including the T/LL171,
which the company said has been
engineered for flexibility, increased life
and reliability.
The other addition to the range is the
T/LL200 Hydrostatic Liquid Level
Sender, which is designed for use in
tanks requiring continuous level measurement of their contents. It provides a
voltage of 4 to 20 mA output, suitable
for connecting into plc- or process-related applications, the company said.
Fozmula said the T/LL171 series sender
has been has been optimized for use in hot
environments. Although it is mechanically
based on one of Fozmula’s previous
capacitance switches, the software has
been reprogrammed. The basic on/off

operation has been replaced, Fozmula
said, with a continuous output of the tank
contents level. The output signal is the
industry standard 4 to 20 mA, but an optional 1 to 5 V signal can also be provided.
Available in a selection of thread sizes,
the unit’s compact footprint minimizes both
its weight and the risk of accidental damage, according to Fozmula. Capable of
being used in fuel tanks, engine oil sumps
and coolant reservoirs, the sender is suitable for all engine fluids, Fozmula said.
The company added that the sender
can operate at shallow liquid depths of just
90 mm and up to a maximum length of
500 mm, and it includes an automotive
Packard-style connector. Electronic devices are known to drift in accuracy when
used at elevated temperatures, such as
tropical climates or when sited in or near
an engine bay. The sender is capable of
sending data accurately in environments
of up to 125°C, the company said.
The T/LL200 sender is for use in
tanks requiring continuous level meas-
urement. It uses the well-established
hydrostatic method of measuring liquid
depth. By compensating for the effects
of extremely variable atmospheric pres-
sures to give precise results, the com-
pany claimed that this technology pro-
duces fewer errors.
