Understanding How Flame Arresters Work

A Flame Arrester (or arrestor) is a passive devices with no moving parts, that allows hot gas to pass through, but stops a flame in order to prevent a larger fire or explosion.  Flame Arresters uses a wound metal ribbon type element that prevents the spread of flame from the exposed side of the arrester to the protected side of the arrester. The metal element's construction provides a matrix of engineered openings that are carefully calculated and sized to quench the flame by absorbing the flame's heat. As an explosion flame travels through a narrow metal space, heat is transmitted to the walls, energy is lost and only vapor gasses are able to pass through. Flame Arresters are used in many industries chemical, petrochemical, pulp and paper, refining, pharmaceutical, mining, power generation, and wastewater treatment.

Cashco Flame Arresters are specifically engineered to match the explosive mixtures Maximum Experimental Safe Gap, in order to ensure complete extinction of the flame. At the heart of each Cashco flame arrestor lies filter discs that consists of wound, smooth and channeled strips of stainless steel set at specific maximum experimental stage gaps the smaller the gaps are which the flame travels the more heat and energy is lost therefore the filters gap width and gap length are specifically engineered to match the explosive mixture in order to ensure complete extinction of the flame.

Environmentally Friendly Design

Conventional SMART sensors include integrated electronics on top of an analog sensor, therefore the still operating electronics must be thrown away once the sensor has reachable the end of its lifetime, adding to global waste.

The SENCOM 4.0 platform includes a reusable SMART adapter, so only an analog sensor has to be removed when it reaches the end of its lifetime, thereby reducing waste and costs.

Easy and Efficient Maintenance

Optional Digital SMART SENCOM™
Expansion Junction Box, BA11

The Maintenance Manager is a data management system that allows technicians to forecast maintenance and calibration frequency, estimate the service life of the sensor, and estimate the life expectancy of the sensor.

Calibration data are stored within the memory chip of the SMART sensor using the SENCOM 4.0platform. Once the sensor is connected to the analyzer, it is possible to download or upload the latest calibration data to the FLXA402 analyzer, thus avoiding the need for field calibration.

Level Instruments for Tank Overfill Protection

Tank overfill incidents in recent years have resulted in loss of life and billions of dollars in damages to petroleum facilities worldwide. One of the worst incidents - the overflow of a gasoline storage tank at Buncefield Oil Depot (U.K.) - has been traced to the failure of level control to maintain containment of the flammable liquid. More common are minor spills that cause significant environmental impact and result in millions of dollars in clean-up fees and environmental agency fines.

In the wake of this incident, the American Petroleum Institute’s (API) Recommended Practice (RP) 2350, the most widely accepted guideline for overfill protection of petroleum storage tanks, has been revised. The fourth edition was published in May 2012 and combined the prescriptive standards of RP 2350 with the functional safety standards of Safety Instrumented Systems (SIS) as described in IEC 61511.

Vital to these new requirements is the application of level instrumentation as one part of a comprehensive Overfill Prevention Process (OPP).

Magnetrol, a world-leader in the design, manufacturer and application of level and flow instrumentation, has written an application document titled "Level Instruments for Tank Overfill Protection". Get your copy here.

The Magnetrol ECHOTEL 962 Dual Ultrasonic Level Control

The Magnetrol ECHOTEL Model 962 is a dual point switch that can be used as a level controller, or to control pumps in an auto fill or auto empty mode. The tip sensitive lower gap performs well in aerated or foamy liquids, and can measure to within 1.4" of the vessel bottom. The rigidity of the unique flow-through upper gap allows separations of up to 125" (318 cm) between the upper and lower transducer gaps.

The Magnetrol ECHOTEL 962 offers the ultimate solution to reliable dual point liquid level measurement. This advanced switch uses pulsed signal technology for superior performance in difficult process conditions, and to provide excellent immunity from sources of electrical noise interference. Extensive self-testing of the electronics and transducer make this advanced switch suitable for use in Safety Integrity Level (SIL) 2 loops.

The ECHOTEL Model 962 is equipped with advanced diagnostics that continuously check the sensor and electronics. The diagnostics also alarm for electrical noise interference from external sources.

Ultrasonic contact switches use a pair of piezoelectric crystals that are encapsulated in epoxy at the tip of the transducer for level measurement. The crystals are made of a ceramic material that vibrates at a given frequency when subjected to an applied voltage. The transmit crystal converts the applied voltage from the electronics into an ultrasonic signal. When liquid is present in the gap, the receive crystal senses the ultrasonic signal from the transmit crystal and converts it back to an electrical signal.
