SITRANS L Level instruments Siemens AG 27 Overview Overview The SITRANS LU1 is an ultrasonic long-range level controller for liquids and solids in a single vessel up to 6 m (2 ft).

1 SITRANS L Level instruments Siemens AG 27 Overview Overview The SITRANS LU1 is an ultrasonic long-range level controller for liquids and solids in a single vessel up to 6 m (2 ft). Hand Programmer shown is an accessory and must be ordered separately. The SITRANS LU2 is a dual point ultrasonic long-range level controller for liquids and solids in one or two vessels up to 6 m (2 ft). Hand Programmer shown is an accessory and must be ordered separately. Benefits Single point, long-range level monitoring Easy to install and easy to program using removable infrared keypad (optional) Compatible with all Echomax transducers Backlit LCD display with reading in standard engineering units Automatic level-to-volume conversion for standard or custom tank shapes Dolphin Plus and SmartLinx compatible High/low alarms Application Application The system consists of a SITRANS LU1 monitor linked to a noncontacting ultrasonic transducer that can be mounted up to 36 m (12 ft) away. The SITRANS LU1 will measure distance, level or volume, and it features patented Sonic Intelligence echo processing software for superior reliability. Readings are displayed in user-selectable linear engineering units on the backlit LCD. An on-board communications port automatically configures for RS-232, RS-48 or bi-polar current loop. The SITRANS LU1 will connect to a DCS or PLC using Siemens Milltronics SmartLinx interface modules, giving you remote 2-way communication and full parameter access. Modules for popular industrial buses can be factory installed or added later to meet changing needs. No external gateway is required, reducing hardware and cabling costs. Key Applications: chemical storage, liquid storage, bulk solids storage (gravel, flour bins, grains, cereals), plastic pellets Benefits Dual point, long-range level monitoring Easy to install; easy to program using removable infrared keypad (optional) Compatible with all Echomax transducers Backlit LCD display with reading in standard engineering units Automatic level-to-volume conversion for standard or custom tank shapes Dolphin Plus and SmartLinx compatible High/low alarms SITRANS LU2 will measure liquids, solids or a combination of both in one or two vessels of different sizes, shapes and configurations up to 6 m (2 ft). The system uses ultrasonic technology to measure level, space, distance, volume or average/differential. It features patented Sonic Intelligence echo processing software for superior reliability. Transducers can be mounted up to 36 m (12 ft) from the monitor. Readings are displayed in user-selectable linear engineering units on the backlit LCD. It features an onboard communications port that automatically configures for RS-232, RS-48 or bi-polar current loop. It will connect to a DCS or PLC using Siemens Milltronics SmartLinx interface modules, giving you remote 2-way communication and full parameter access. Modules for popular industrial buses can be factory installed or added later to meet changing needs. No external gateway is required, reducing hardware and cabling costs. Key Applications: chemical storage, liquid storage, bulk solids storage (gravel, flour bins, grains, cereals), plastic pellets, tripper car /11 Siemens FI 1 28
