Flow switch
Set point, by-pass design
The 2600 flow switch operates by either set point mode or by-pass mode. A magnetic shuttle, displaced at increased or decreased flow from the calibrated set point, activates a sealed reed switch inside the removable bonnet. The by-pass mode operates for high flow but maintains a very low pressure drop. Made from PVC, stainless steel and ceramic, units operate to 140F and to 150 psig, with in-line 2-inch slip ports that take a variety of adapters. Thomas Products, www.thomasprod.com Enter 613

Flow controller
Pilot module interface
Smart-Trak(TM) digital mass flow controllers feature Dial-a-Gas(TM) programming calibrated for ten gases used in pharmaceutical, biotech, analytical, and other research applications. Instruments can be dropped in as replacements or OEM, and operate in closed, normal or purge modes from a PC or pilot module. RS232 output and two analog outputs are available. Units are made of stainless steel, in ranges from 0 to 10 sccm to 0 to 50 slm, for any clean gas flow including toxics and corrosives. Sierra Instruments, www.sierrainstruments.com Enter 617
TPE butterfly valve
No welding, assembly operations
TPE butterfly valves regulate heated radiator coolant flow from engine to heater core and replace stamped steel, welded components. Reportedly reducing manufacturing costs by 80%, TPE simplifies units to one piece and strengthens them for use at 190F for long periods. Features include flex fatigue resistance, high and low temperature resistance, tight part tolerances, and excellent compression set. Minnesota Rubber, www.mnrubber.com Enter 618
Flow indicator
Output range up 0 to 0.012 inches3 per cycle
Sight-Rite(TM) flow indicators are recommended for equipment applications needing visual inspection of critical flows within safety margins. The units confirm that minute amounts of liquid have been dispensed, using LED lights. The units are reportedly dependable for applications including manufacturing, packaging, food processing, printing, and chemical processing. Site-Rite is designed for use with PurgeX(R) injector pumps and other lubrication and process lines. Oil-Rite Corp., www.oilrite.com Enter 619
Pressure regulator
Regulates air or water pressure
An OEM series of pressure regulator transducers is ideal for use in air or water pressure control applications, the company says. The MPR series features a low-torque, lockable adjusting knob that reportedly offers easy and precise adjustment. Relieving units are typically used for air; non-relieving units for water. Applications include OEM equipment, printing presses, medical or spray equipment, analyzers, pumps, compressors and welding machines. Dwyer Instruments, www.dwyer-inst.com Enter 620
Water-jet pump
Cuts fluid end conversion
Pumps that have a unique swing-out fluid end for easily changing plungers and related components reportedly convert in 20 minutes. Available for a range of pressures, flows, and horsepower, they convert without requiring manifold or gauge change. The 225-series pumps are can be ordered with a 200, 230, or 275 hp diesel engine and provide 10 to 38 gpm, with a triplex design and hard-coated valves and plungers. Pumps are built from stainless steel components. NLB Corp., www.nlbcorp.com Enter 621
Flow checker
With feed verification
The Flow Checker is an oval gear meter for PZ pumps that mounts directly to the discharge of the PZ, PZi4, or PZi8 and provides 1 pulse output for each ml of liquid. Connected to PLC or controller, meters provide feed verification to manage chemistry and monitor drum inventory. Flow Checker output can be connected to a flow counter for display of instant and total flow, in English or metric units. Neptune Chemical Pump Co. Inc.www.neptune1.com Enter 622
Flow meter
Provides true mass flow signal
Unobstructed mass flow meters for gas and liquid feature true mass flow signal, 316L, low sulphur stainless steel, welded construction, and clean-in-place design.
