Vibratory level switches
05 September, 2008The Sitrans LVL100 and LVL200 vibratory switches are suitable for high and low detection of all liquid media, independent of mounting position. The compact, user-friendly switches measure reliably in dynamic conditions, such as variations in the dielectric permittivity of a medium or the formation of vapour or bubbles.
Guided wave radar level sensor
05 September, 2008The Flexar is a continuous level measurement sensor used for monitoring the amount of material within tanks, silos, bins and many other types of vessels. It is used to measure the level of powders, granular and liquid materials and is a universal technology for use in a wide range of applications and industries.
Level sensing for sewage lift stations
23 August, 2008 by Rob Knowles*The level sensor is a small but vital component in sewage lift or pump stations to maintain system integrity and avoid unwanted spillage.
Deep vessel level sensor
05 August, 2008To measure levels beyond 12 m distances in storage vessels, users had two primary options: use complex 4-wire ultrasonic devices or install expensive radar-based instruments. Now, Endress+Hauser have launched the Prosonic M FMU 44 — a 2-wire loop-powered, non-contact ultrasonic level sensor that measures levels in tanks and silos up to 20 m.
Level detection switches reduce hazardous spills
25 July, 2008It is critical that plant managers and engineers choose the right level detection switches as they can prevent the accidental discharge of toxic products into the environment. A well-selected, correctly installed level switch will save companies the expense associated with treating and disposing of spilt material. Moreover, it will safeguard companies against punitive fines in the event of an unavoidable accident.

2-wire level switch
08 July, 2008The NuTec LS2000 level switch from Fluid Components International is designed for 2-wire, 4-20 mA loop power that allows the LS2000 to serve as a drop-in replacement for other 2-wire mechanical float and paddle switches without any wiring modifications during plant retrofit projects, which simplifies installation and reduces cost. The LS2000 is also available for 115/230 VAC or 24 VDC input power and a 6 A relay output.
Self-validating point level sensor
08 July, 2008The SafePoint from Monitor Technologies LLC is a self-validating point level sensor for monitoring the presence and absence of powders, granular materials and other bulk solids. It is completely fail-safe and can be used in bins, silos and other vessels with process temperature conditions up to 399°C to shut off bin filling and protect against overfilling due to unknown sensor failures.
Gladiator vibration level switch
08 July, 2008The level sensing arrangement used in the Gladiator vibration smart switch is suitable for a wide range of liquids and solids, including slurries and pelletised materials.
VersaLevel radar level instruments
08 July, 2008Honeywell has introduced a family of microwave radar level instruments for use in plant storage tanks. The VersaLevel line is manufactured to Honeywell’s standards and specifications by German-based Krohne.

Hawk joins Brazil's MS Instrumentos
26 June, 2008Hawk, a global provider of level, positioning and flow measurement technology, has announced a joint venture with MS Instrumentos in Brazil.
Seeking self-adjusting instruments
12 June, 2008 by John Immelman*Modern process instruments incorporate a fair degree of intelligence used to optimise process variable accuracy and reliability, and can even undertake predictive maintenance. But they fail miserably in two critical aspects even when compared with technologies we use every day — self-adjustment and self-healing.
Overflow monitor
19 November, 2007Pulsar's SludgeFinder sludge level monitor uses a self-cleaning acoustic sensor that sits under the liquid surface of a clarifier or sludge tank. An acoustic signal is bounced off the bottom of the tank and modulations in the returning signal are interpreted to provide a profile of the sludge in the tank.
