Reflective Ultrasonic Multi-Function Liquid Level Transmitter

UG01 & UG03

Application



The general purpose reflective ultrasonic multi-function level
transmitter provides continuous level measurement up to 9.8’
(3m) with a 4-20 mA analog signal output and four relays, and
is configured via our WebCal software. The non-contact liquid
level sensor features our proprietary Reflective Technology™ that
delivers reliable level measurement in condensing environments.
Each relay can be configured for alarm, automatic fill or empty
functions. Select this sensor for small tanks with non-foaming or
mildly vaporous media such as chemicals, water, wastewater and
oil. Typical applications include day tank, IBC or drum, cooling
tower, skid or machine, process tank and waste sumps.

Features

Offered in 1.5m (4.9’) and 3m (9.8’) measurement ranges

Fail-safe diagnostics with selectable relay and signal outputs

Narrow 2” (5cm) beam width for applications with limited space

Corrosion resistant PVDF transducer and compact PP enclosure

Short 1.5” (3.8cm) dead band maximizes tank filling capacity

Automatic temperature compensation from -40º to 80º C.

Four programmable relays with embedded level control logic

• 1 pump or valve with 3 alarms

• 2 pumps lead-lag with 2 alarms

• 2 pumps duplexing with 2 alarms

• 4 independent switch point alarms

Reflective Technology

Condensation is the most common variable in
liquid level applications. Condensation attenuates
the acoustic signal of ultrasonic sensors with
horizontal transducers, weakening their signal
strength and signal to noise ratio by up to 50%,
and substantially reducing their measurement
reliability. At the core of Reflective Technology™
is a simple fact. Unlike flat horizontal surfaces,
significant water droplets cannot adhere to
smooth vertical surfaces. By orienting the
transducer vertically, condensation runs off
the transducer and does not affect sensor
performance. The unimpeded transmit and
receive signals are redirected to and from the
liquid off a 45º reflector, delivering reliable level
measurement. Thanks gravity.
