TW-260 series provides a
cost-effective solution for precision liquid level
measurement needs.
They are simple, inexpensive, yet practical means of
continuously indicating levels in tanks, canals and
reservoirs.
With constant torque spring instead of counterweight
used in a conventional Float-Operated level transducer,
TW-260 series level transducer can easily be installed,
and requires only a small stilling well as necessary.
With built-in CMOS counter module triggered by the reed
relays and magnetic disk instead of conventional shaft
encoders, TW-260 offers an absolute readings with less
component and cost to provide a precision level
measurement.
TW-260S may be connected directly to data-logger, it
also may be connected to a transmitter with RS232,
RS485 or 4-20mA output thus linked to remote monitoring
system or SCADA. Except for the data string echoed to
request from transmitter, TW-260S outputs a pulse at
every level change for event trigger so that the
wireless transmitter would send the rising data at the
first second for warning to accident.
