More information about how a Level sensor works in this link.
OMEGA’s LVCN210 Series
ultrasonic level transmitter and
controller provides continuous level
measurement up to 3 m (9.8') with
a 4 to 20 mA signal output, and is
configured via our free software download. The
level sensor has 4 programmable
relays with selectable hysteresis and
fail-safe logic. The embedded level
controller can lower cost by
replacing external control hardware.
This non-contact liquid level sensor
is ideally suited for corrosive, sticky
or dirty liquids, and is widely
selected for day tank, skid,
IBC, sump and process tank
