Level transmitter

The ORCA Sonar Series Interface level transmitter uses a wide range of sonar transducer frequencies for continuous level measurement. The product features industrial scum-cleaning mechanisms that continually clean the device, enhancing reliability. The product is suitable for use in a range of water and wastewater treatment applications. Hawk Measurement America. www.hawkmeasure.com.

Portable traffic signals

The company's portable traffic signal and control system provides a convenient, safe alternative to exposing human flag-gers to traffic. All signals come with bright 12-in. LED lights. The signals can be controlled remotely, programmed to change at fixed times, or set to be controlled by traffic. The equipment can be stored and transported in an optional trailer. Horizon Signal Technologies, www.horizonsignal.com.

Quick-set leak stop

AV-290 Fast-Set is a two-component, hydrophobic polyurethane foam grout that stops high-volume leaks around manholes, pipe joints, storm drains, culverts, and other problem areas. It comes with both components inside an easy-to-work tube. It reacts within 3 seconds of application to form a firm, dense foam that is tack-free after 25 seconds. The foam contains no solvents or VOCs. Avanti International. www.avantigrout.com.

Pipe sealant

Hydra-Eze Compound is a nondrying thread sealant and anti-seizing material that provides favorable performance and durability. It can be used on brass, iron, steel, aluminum, copper, polyvinyl chloride, and fiberglass-reinforced pipes, in any application where it comes in contact with potable water. The product comes in an easy-to-use 9-oz. tube. Assured Flow Sales Inc. www.gradelok.com.

Gate valves

AWWA C515 gate valves feature three different connections: push-on, flange-x-flange, and mechanical joint. Each is coated with fusion-bonded epoxy, and each comes with a standard 2-in. operating nut (a hand wheel is optional). The flange-x-flange valves come in sizes from 2½ to 16 in.; the push-on and mechanical-joint versions come in sizes from 2½ to 12 in. The valves are intended for installation on potable water lines, waterworks connections, irrigation systems, and fire systems. Danfoss Flomatic Corp. www.flomatic.com.

Storage-tank pressure sensors

Series 52 sensors, with digital instrumentation, help prevent tank overflow. Data can be read directly from the sensors, or remotely. Operators can use the devices to control the pumps filling tanks via remote. The sensors permit direct mounting of gauges, pressure switches, and transmitters. In addition, the sensors can be powered by battery, loop, or equipment voltage. Red Valve Co. Inc. www.redvalve.com.



Vacuum-assisted pumps

These nonclog pumps come in models from 4 to 16 in. and are suitable for a range of applications. The units are fully automatic, dry priming, dry running, and portable. They can handle flows up to 12,000 gal./minute and heads up to 200 ft. Also, the impellers can tackle spherical solids up to 3 in. and larger. Choose from diesel or electric pumps; a trailer-mount version is available. Griffin Pump and Equipment. www.griffinpump.com.

Stormwater chamber

The Recharger V8 retention/detention chamber offers 25% greater capacity in comparison to similar products. The product includes overlapping rib connections, which helps simplify installation and strengthen the connection between chambers, and its built-in manifold system eliminates the need for additional header systems. Each chamber is made of high-density polyethylene, which delivers greater chemical resistance to parking lot runoff than polypropylene. Cultec Inc. www.cultec.com.
