Wireless Leak Detection for Tank Farms

Tyco Thermal Controls is the world leader in liquid leak detection solutions for the industrial, commercial, and environmental markets. The TraceTek® group of Tyco Thermal Controls has teamed with the Rosemount Division of Emerson to combine state-of-the-art tank overfill and leak detection with efficient and cost effective low power mesh radio technology. The combination of TraceTek’s TT5000 hydrocarbon sensing cable and TT-FFS fast acting fuel sensor probes with Rosemount 702 Wireless Discrete Transmitter for Hydrocarbon Leak Detection allows tank farm operators to get immediate notification of liquid leaks or overfills when and where they happen.

One of the main obstacles to the deployment of leak detection technology has been the relatively high cost of hard wiring the leak detection sensors back to control room alarm panels. In some instances the signal cables and installation costs within the tank farm’s classified areas has amounted to more than 60% of the total system cost. Emerson introduced their Smart Wireless mesh network solution to address the high cost of hazardous area wiring for a variety of pressure, temperature and flow monitoring applications. Now leak detection has been added to the mix.

TraceTek and Rosemount have jointly developed a capability to couple TT5000 fuel sensing cable or TT-FFS fast acting fuel sensor probes to Rosemount’s 702 transmitters. When a facility installs multiple 702 transmitters, they self-organize into a mesh network that relays leak sensor data back to the control room. Users have the option of transferring data directly from the Emerson Smart Wireless Gateway into their SCADA system or they can use a TraceTek TTDM-128 Alarm Panel dedicated to leak detection.

The system has worldwide CID1 approvals from FM and ATEX/IEC Zone 0 approvals from Baseefa. Radio spectrum approval is in place or pending in over 200 countries.

For over 20 years, TraceTek systems have been at the forefront of  leak detection technology, and the combination with Emerson’s Smart Wireless system gives tank farm and refinery clients the opportunity to deploy overfill and leak detection sensors at a cost far below what was possible as recently as last year.  Emerson’s mesh network systems have been successfully deployed at more than 1200 sites around the world and the new addition of wireless leak detection will be an attractive and easy to deploy enhancement. For those sites contemplating leak detection for the first time, the dramatic reduction in installed cost can be the catalyst that gets the ball rolling.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
