LVU501 Reflective Ultrasonic Level Transmitter 08886

 The LVU500 Series general purpose reflective ultrasonic multi-function level transmitter provides continuous level measurement up to 3 m (9.8’) with a 4-20 mA analog signal output and four relays and is configured via web calibration 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 chemicals, water, wastewater and oil (non-foaming and/or highly vaporous liquids). Typical applications include day tank, IBC or drum, cooling tower, skid or machine, process tank and waste sumps.

• 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.
