Noninvasive leak detection

LeakTuner™ locates leaks in water distribution pipelines without breaking ground or disrupting service. The wider range of frequency settings reduces both electronic white noise and ambient background noise when testing for leaks. The detection is designed to listen for leaks through headsets that connect to acoustical sensors, which are directly attached to pipes, hydrants, valves, or fittings. Echologics Engineering Inc. (Mississauga, Ontario).


Safety-light curtains 

The EZ-SCREEN® low-profile safety-light curtain with integral muting is designed for use on smaller production machines. It provides optimal performance in compact spaces, yet is robust enough for large power presses. The models feature increased mounting flexibility, hookup options, and functionality. The two-piece optoelectronic safeguarding device creates a screen of synchronized, modulated infrared sensing beams that extend from end to end of the housing to ensure that operators are completely protected from machine safety hazards. Banner Engineering (Minneapolis).


Temperature sensor 

Series TE-A Averaging Temperature Sensors measure the temperature in large ducts and air-handler units. Bendable aluminum capillaries are available in 6-, 12-, and 24-ft lengths. These capillaries consist of four thermistor or resistance temperature-detector sensors, which are internally averaged to give a single output signal. Series CC1 mounting brackets mount the capillary to the wall of the duct or air handler without kinking the sensor wires inside the probe. For faster installation, the enclosure has multiple knockouts, wide mounting ears, and a screw-off captured lid. Dwyer Instruments Inc. (Michigan City, Ind.).


Water-level meter 

The Model 101 P7 Water Level Meter features the Solinst laser-marked flat tape and a submersible probe. The P7 probe is engineered to allow submersion to 1000 ft (300 m), making it ideal for depth to water, as well as total well-depth measurements. The sensor, which is near the tip of the probe, provides consistent measurements in wells, boreholes, tanks, and cascading water with almost zero displacement. The design of the tape seal plug is intended to make probe replacement quick and easy. Solinst Canada (Georgetown, Ontario).


Multigas scrubber 

NRP 90 and NRP 135 air scrubbers are small-footprint, multigas scrubbers that automatically turn on and off using electronically controlled sensors. The units operate on alternating current or battery power and can be used in manholes, pump stations, lift stations, and confined spaces. NRP Group (Cleveland).


In-conduit hydropower system 

The LucidPipe™ Power System, a patented in-pipe turbine generator, enables industrial, municipal, and agricultural facilities to produce clean, reliable, low-cost electricity from their gravity-fed water pipelines and effluent streams. The water-to-wire energy recovery solution takes advantage of the untapped energy of already flowing water to generate millions of megawatt hours of electricity with no environmental impact. Lucid Energy Inc. (Portland, Ore.).


Carbon dioxide detector 

The Model IR700 infrared point detector is designed to offer reliable carbon dioxide readings with little maintenance and no routine calibration. The detector provides complete control-room status and control capability for monitoring at the parts-per-million level. The detector features a precision infrared sensing element that offers reliable protection against carbon dioxide gas leaks. It also features heated optics to eliminate condensation. Before the lenses become entirely blocked, a dirty-optics indicator informs the user that the device must be cleaned. The detector operates at a temperature range of –40°C to 50°C (–40°F to 122°F) and a humidity range of 10% to 95% relative humidity — noncondensing. General Monitors (Lake Forest, Calif.).


Side-bend tester 

The Guided Side-Bend Tester performs a qualitative test of a fusion joint by destructively testing a coupon. The device tests the ductility of polyethylene pipe fusion joints in a safe, quick manner. Operators can perform a bend-back test on polyethylene pipes with 1 to 7 in. of wall thickness. The unit is compact and requires a planer, calipers, and saw to complete the testing procedure.
