Tracer 1000 Aids Wastewater Treatment Plant

Engineers at a wastewater treatment plant (WWTP) in Ohio have selected Flow Line Options' Tracer 1000, an advanced radar level transmitter, for the plant's influent water-flow system. Featuring Time Domain Reflectometry, commonly known as TDR, the Tracer 1000 provides continuous radar level measurement and point level detection in liquids, with analogue and switching output. Tracer 1000 is suitable for a diverse range of level applications and has almost no installation restrictions.

The device has a 1in radar beam that can be mounted in small tanks, tall and narrow nozzles, and it measures precisely even with difficult tank geometries or close-to-interfering structures. The radar level technology was installed by the City of New Philadelphia as part of its overall initiative to address increased flows to the wastewater plant. The Tracer 1000 analogue output is connected to a field-mounted monitor that allows plant operations to verify onsite influent flow rates.

The flow monitor also reports back to the plant SCADA system using integral 4-20mA output. The data collected by the radar level system has helped address an ongoing problem with infiltration and inflow. The information collected by the radar level system is used to determine the amount of water coming into the plant. The plant processes an average flow of 3MGD with a design capacity of 5MGD. The radar level system is currently being used in a wet-well application.

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.
