SITRANS LU10 Ultrasonic Level Monitor (DISCONTINUED)
- Ultrasonic Long-Range Level Monitor Specifically for liquids and solids offering 10-point monitoring in a single unit
- Superior Reliability Delivered by featuring patented Sonic Intelligence echo processing software
- Ideal for Tank Farms Cost effective
Overview
PRODUCT DISCONTINUED - REPLACED BY THE LUT400, LR560, OR THE RD500 (APPLICATION DEPENDENT)
SITRANS LU10 is a long-range ultrasonic level monitor for liquids and solids that provides 10-point monitoring. It can be used in a wide range of applications to scan liquids, solids or a combination of both contained in vessels of differing size, shape and configuration up to 60 m (200 ft).
The LU10 level monitor uses ultrasonic technology to measure level, space, volume, distance or average/differential. It features patented Sonic Intelligence® echo processing software for superior reliability. Transducers can be mounted up to 365 m (1200 ft) from the monitor. The LCD displays readings in user-selectable linear engineering units.
The LU 10 ultrasonic level monitor will connect to a PLC or DCS using Siemens SmartLinx® interface modules, providing remote 2-way communication and full parameter access. Modules for popular industrial buses can be factory installed or added later to meet changing requirements. The unit doesn't require an external gateway, which reduces hardware and cabling costs. (handheld programmer shown is an accessory and must be ordered separately.)
Key applications include chemical storage, liquid storage, bulk solids storage (sugar, flour bins, grains, cereals), plastic pellets and tank farms.
Benefits
- Ten point, long-range level monitoring
- Automatic level-to-volume conversion for standard or custom tank shapes
- Easy to install, easy to program using removable infrared keypad (optional)
- Backlit LCD display with reading in standard engineering units
- Dolphin Plus and SmartLinx® compatible
