Ultrasonic Level Transmitter
LVU-2001 Series
UAccurate and Reliable Level Measurement From 15.2 cm to 3.7 m (0.5 to 12')
UFixed Range–No Programming Required
ULow-Cost Solution for OEM and Process Applications
UCompact Size and 5 cm (2") Transducer for Small Tanks
UPP Enclosure Rated NEMA 4X (IP65) with PVDF Transducer
UFail-Safe Intelligence Provides Maximum Process Safety
The two-wire, bulk tank ultrasonic level transmitter is mounted through the top wall of the tank and provides non-contact measurement up to 3.7 m (12'). The range is fixed:
4 mA = 144" or 12' (distance from sensor) and 20 mA = 6" or 0.5'. No programming is required. With non-contact technology, the transmitter is an excellent choice for applications with dirty, coating,
corrosive type liquids. The compact design is the perfect size for small tank applications.
A high-frequency ultrasonic sound wave is pulsed three times per second from the base of the transducer. The sound wave reflects against the
