Vibrating point level switch
25 June, 2009 bySiemens has added the Sitrans LVS100 to its line of vibrating point level switches for high, low or demand levels of dry bulk solids in bins, silos or hoppers.
Tank level switch
25 June, 2009 byThe FLT93 tank level switch from Fluid Components International is now rated for Safety Integrity Level (SIL) 2-compliant service. It has been classified as a Type A subsystem in accordance to IEC 61508-1 with a hardware failure tolerance of 0. The probability of failure on demand (PFD) meets SIL-2 capability standards.
Ultrasonic level sensor
09 June, 2009 byGems Sensors & Controls has launched the UCL-520 ultrasonic level sensor. The UCL-520 Series is suitable for non-contact applications such as industrial water treatment, wastewater management, chemical and petroleum distillates storage as well as many other challenging fluid applications.
Failsafe level alarm relay and probe
11 May, 2009 byMultiTrode has released the SafeSmart level alarm relay and failsafe probe that provides an additional failsafe detection.
Radiometric measurement — at home in extreme process conditions
06 April, 2009 by Simon Rigling*Radiometric measurement, also known as nuclear- or gamma-based measurement, is an extremely reliable and safe, non-invasive solution that is suitable for level limit detection, continuous level measurement, and density and interface layer measurement.
Interface level detection — what to consider
19 March, 2009Compared to standard level measurements in liquids, the detection and measurement of interfaces has its own particular challenges, leaving many interface applications without reliable level measurement. Most popular today are the electronic or non-mechanical solutions with no moving mechanical parts which offer much higher long-term stability and low-maintenance operation.
Silo level measurement
15 March, 2009 byThe Silopilot FMM20 is an electromechanical level measuring device featuring an uncomplicated but rugged construction that is unaffected by silo geometry, dust, temperature, low dielectric values and static electricity. The simple-to-operate Silopilot FMM20 is suitable for use in bunkers and silos holding light bulk solids such as wheat, plastic granules and powder.
Level measuring instrument
01 November, 2008The Liquicap T continuous level measuring instrumentation for liquids features a build-up compensation mode that overcomes performance problems normally associated with conventional capacitance/inductance level measuring probes, particularly in chemically aggressive, sticky liquid applications.
Sonar transducer for level control
01 November, 2008The line of ‘fourth-generation’ sonar transducers designed for improved sensing of interface levels in clarifiers and thickeners is available. The sensors claim improvements in overall power, penetration and calibration density range. They provide better capability under high suspended solids loading, ‘sliming’ and generally upset process conditions.
Vibrating fork level switch
01 October, 2008The NWS liquid level switch is designed as a 2- and 3-wire switch and can be universally used in vessels and pipelines. The NWS operates on the tuning fork principle in air at resonance frequency. A piezoelectric crystal is used for excitation of oscillations and for monitoring the actual oscillation frequency.
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.
