Measurement and Testing Versatile Power Supply for the Field Technician
Setting up a Fieldbus infrastructure often involves installation work at remote locations with no power supply in sight. At the same time, the DCS and its associated infrastructure is far from being ready to perform remote fieldbus physical layer testing. For the field technician, this would usually mean the lack of on-site device diagnostics in order to get the system up and running within the limited time available.
The new mobile Fieldbus Battery BP-FBPS-1.30.1 from Pepperl+Fuchs is the ideal means to provide the power for on-site fieldbus diagnostics. It offers an adjustable output between 15 V and 30 V at 1 A max., making it the ideal match for the mobile Advanced Diagnostic Module (ADM) by Pepperl+Fuchs. In combination with devices requiring up to 500 mA of power, the unit provides sufficient energy for up to 8 hours of on-site work without recharging. The rugged housing offers IP54 protection to make it splash and rain proof. The battery comes fully equipped with built-in tools, such as current display and over/under termination.
With the new mobile Pepperl+Fuchs’ (Germany) Fieldbus Battery, field technicians are able to power up any PROFIBUS PA and FOUNDATION Fieldbus H1 infrastructure, test it with the ADM and create the associated documentation directly on site. As a result, loop tests will commence without problems and last minute troubleshooting will be a matter of the past. The new mobile Fieldbus Battery BP-FBPS-1.30.1 is now available for immediate delivery.

GE Analytical Instruments’ (USA) has recently supplied several major oil companies with its Leakwise Oil-on-Water Monitoring Systems to monitor their large tank farms. Multiple Leakwise ID-223/2000 detectors have been installed near tanks to detect tank overfill, hydrocarbon build-up, and oil spills and leakages from pipes, pumps, valves and tank dewatering.
Leakwise ID-223/2000 sensors can detect and monitor oil layer buildup in the range of 0.3-25 mm on water or dry ground. They use wireless radio transmitters for sending status and alarm signals to a receiver located in a remote control room. The receiver, which can handle multiple transmitters, is connected via a modbus protocol to a Leakwise digital controller which has Modbus output to the customer's SCADA. The controller can relay outputs for alarm and control as well as Cellular GSM transmission of SMS messages to tank farm managers, operators, and fire fighters.
Offshore, the Leakwise ID-227W Oil-on-Water Sensor is monitoring desalination plant intakes, oil ports, and rivers to detect oil spills from boats or local industries. The Leakwise ID-227WL is mounted on a wave rider buoy with both solar power and a powerful point-to-point transmitter that can send signals as far as 20 km. The ID-227WL will soon be available with cellular transmission of alarms and status reports to multiple mobile phone numbers.

Infrared Analysers For On-Site Oil/Grease Measurements in Water and Soil Featured in New Brochure
The InfraCal TOG/TPH Analysers for oil/grease concentration levels are highlighted in a new brochure published by Wilks Enterprise, Inc (USA). These analysers are specifically designed for easy, on-site infrared measurement of total oil and grease (TOG), total petroleum hydrocarbon (TPH), and fat, oil and grease (FOG) concentration levels in water and soil samples. The InfraCal TOG/TPH Analysers are used worldwide for analysing produced water on off-shore platforms or wastewater in refineries, industrial plants or treatment facilities and soil studies at remediation sites or around underground storage tanks. Typical analysis time is under 15 minutes, including extraction process.
The InfraCal TOG/TPH Analysers have been used by the Water Environment
Research Foundation (WERF) to evaluate performance of grease interceptors and their effect on wastewater, by the ASTM to develop Method D 7066-04, and by numerous companies to meet new European discharge regulations. InfraCal TOG/TPH models are available for use with a wide variety of extracting solvents such as hexane, pentane, Vertrel MCA, Freon, hydrocarbon-free grade of perchlo-roethylene, S-316 or AK-225.
All InfraCal analysers are portable (operable from a 12 volt dc power supply) and weigh less than 5 lbs. Pushbutton, user-friendly operation makes them easy to use with minimal training. The analysers can read out in infrared absorption values or they can be calibrated to display concentrations directly in any desired format such as ppm or milligram/kg. A wide range of accessories, such as printer and carrying case increase the versatility and capabilities of the Infracal TOG/TPH Analyser.

Watchdog Guards Against Tank Overfill
Afriso’s (Germany) NB 220 QSA Watchdog overfill alarm system, consisting of the type 76...(A, C, E, M, N) level sensor and the NB 220 QSA transducer which serves as a level controller, is designed to prevent overfilling of tanks with water-polluting liquids. The overfill alarm system may be used with stationary tanks for storing inflammable and non-inflammable water-polluting liquids (such as fuel oil EL, biodiesel, diesel, gear oils, hydraulic oils and vegetable oils). The level sensors may be used for fluid temperatures between –25°C to +50°C (version H up to +80°C).
Operational safety is high since the unit continuously monitors the characteristic of the level sensor and checks for short circuits and cable breaks between the level sensor and the level controller. If a signal is generated, the filling process is interrupted and the unit triggers audible and visual alarms.
Control lamps as well as a test and a reset button at the front ensure easy operation. The NB 220 QSA transducer is supplied with AC 230 V; 2 voltage-free changeover contacts (1 can be reset) are available for alarm and control devices. The overfill alarm system is optionally available as NB 220 QSA-AC 24 V for supply with AC 24 V or as NB 220 QSA-DC 24 V for 24 V direct voltage. The additional device type 907 Z can be connected to the transducer as an additional control unit to enable connection to a tank lorry with a filling system.
