Centennial Plastics Geothermal Exchange Pipe Provides Ease for Installers Centennial EarthLoops from Cen- tennial Plastics Inc. allow for efficient vertical and directional boring for geothermal contractors. The patented one-piece Centennial Bullet U-Bend fitting guides the EarthLoops down the borehole with ease. Contractors can now eliminate the time-consuming chore of fusing pipe to fittings. Coils of geothermal Cen- Fuse pipe are securely fused to the Centennial Bullet U-Bend fittings at our manufacturing facility. The result is its exclusive Centennial EarthLoop, which is ready to install the moment it arrives at the job site. Centennial Bullet U-Bend Fittings ac- commodate CenFuse pipe in ¾-inch, 1-inch, and 1¼-inch diameters. www.centennialplastics.com Solinst's Narrow Coaxial Cable Water Level Meter Offers Greater Flexibility The Solinst Model 102 water level meters use narrow cable and segmented probes to measure water levels in tight spaces. This option offers greater flexibility in angled piezometers and assists in bypassing downhole restrictions or pumps when measuring drawdown. The P1 probe is ¼- inch in diameter and has 12 stainless steel weights. The cable has a tough polyethylene jacket with laser markings each 1/100 feet. It is available in lengths to 1000 feet. The Model 102M mini water level meter comes with either 80 feet or 25 meters of cable on a small portable reel. www.solinst.com Boshart Industries Designs New Line of Industrial Pitless Units Boshart Industries launches a line of industrial pitless units and will be available in sizes 5 inches through 12 inches in both ductile iron and stainless steel. They are NSF certified, baked epoxy finish provides excellent corrosion resistance; flanged connections, all units 8 inches and larger are supplied with raised face flanges for positive sealing on all three connections which simplifies the installation process and eliminates cor- rosion due to galvanic action between dissimilar metals. The five through passages for pump cable, airlines, con- trols, and chlorination equipment allow access to the well for testing and meas- urement equipment. www.boshart.com Featured PRODUCTS WWJ February 2015 59 Twitter @WaterWellJournl ee r F an h s c 's ebina w ou help y ars!
