Materials Handling


the reception range varies from a few centimetres to several metres. Substances measured in this way include liquids, creams, pastes and granular materials such as cereals, sands and gravels. As ultrasound sensors work contact-free, the sensor is protected from wear and tear and aggressive fluids, and the material being measured is protected from contamination. Ultrasound metres are also very tolerant to dirt such as dust, smoke, steam and fluff. Baumer describes capacitive sensors as the true all-


rounders of level measurement technology. “They are robust and suitable for many different uses because they can be used for detection of practically any medium,” notes the company. In a robust all-metal housing they are also suitable for use in aggressive media with direct contact. If the medium does not allow direct contact, they can also see through (non-conductive) container walls. They are not troubled by adhesions or dirt, nor can the medium be contaminated by the sensor. From Siemens, SITRANS LU10 is an ultrasonic long-range level monitor for liquids and solids, offering 10-point monitoring in a single unit. 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 metres. SITRANS LU10 uses ultrasonic technology to


measure level, space, distance, volume or average/ differential. Transducers can be mounted up to


365 metres from the monitor. It features patented Sonic Intelligence echo processing software for superior reliability, while readings are displayed in user-selectable linear engineering units on the LCD. The monitor will connect to a DCS or PLC using


Siemens SmartLinx interface modules, giving users remote two-way communication and full parameter access. Modules for popular industrial buses such as PROFIBUS DP and DeviceNet can be factory installed or added later to meet changing needs. No external gateway is required, reducing hardware and cabling costs. Key applications include chemical storage, liquid


storage and bulk solids storage such as sugar, flour bins, grains and cereals, and plastic pellets. For its part, Honeywell’s SmartLine non-contact


radar level meter measures distance, level, volume and mass. Based on frequency modulated continuous wave (FMCW) technology, it provides a more stable measurement than pulse radar and is well suited for agitated process conditions and the most demanding applications. SmartLine can measure the level of a wide range


of liquid or granular products on a large variety of installations, including LPG and LNG. The level meter does not require calibration or commissioning when installed and can be applied in agitated process conditions and agitated vessels. The product is available in two versions; the RM70 has its electronics designed
