The LVCN700 Series has been discontinued. Please see the
LVCN210 Series as a possible alternative or contact our Flow Engineering department.
The LVCN700 Series general
purpose ultrasonic switch provides
non-contact level detection from up
to 8 m (26') away, and has 3 relay
outputs. Each relay can be
configured on a single setpoint
alarm, 2 latched setpoints for
automatic fill or empty including
lead-lag, or 2 independent setpoints
for out-of-bounds alarms. In
addition, relays 1 and 2 can be
interlocked for relay alternation or
duplex operation. The switch is well
suited for a broad range of
corrosive, waste and slurry-type
media, and is broadly selected for
atmospheric day tank, pump lift
station and waste sump applications.
