When used in professional spray polyurethane foam (SPF) equipment, AW-Lake JVM Series Positive Displacement Gear Flow Meters offer a consistent and ultraprecise method for dispensing chemicals that create the foam for smaller commercial projects such as taxidermy, boat manufacturing, and sound insulation products. In operation, an SPF machine pumps chemicals from two multi-gallon drums through hoses to the nozzle of a spray gun to form the polyurethane foam. A pump within the spray foam equipment is not reliable enough to dispense accurate amounts of chemical.
Unlike pumps, the AW-Lake JVM Series Positive Displacement Flow Meters are not prone to drift, overspin, or media slippage under pulsation that results in ultra-precise chemical batching for the SPF machine over time. To ensure longevity and chemical compatibility, the positive displacement flow meter features a ball bearing design that works well in lubricating media, such as the chemicals used in this application.
City Fireboats Use AW-Lake Turbine Flow Meter to Measure Fire Retardant Foam
In another application, city fireboats are using AW-Lake Turbine Flow Meters and Transmitters to measure fire-retardant foam for extinguishing fires. Fitted on foam lines, the AW-Lake TRG Turbine Meters provide feedback to the PLC on actual flow rate volumes. AW-Lake’s RT-30 Flow Transmitters accept the turbine’s pulse input and display readings locally while providing a 4-20mA output signal to a PLC to control the opening and closing of the valves for the desired ratio.
AW-Lake’s TRG Turbine meters were ideal for this project due to their rugged stainless-steel body construction, material compatibility with the low viscosity fluid, and most importantly their compact size and small face-to-face dimension.
AW-Lake, a TASI Group company, was founded in 1984 as a manufacturer of flow meters and flow monitoring equipment, servicing industrial paint and hydraulics applications. After a strong start in the Automotive sector, AW-Lake diversified into many other industrial markets, including Oil & Gas, Pharmaceuticals, Medical Equipment, Power Generation, General Manufacturing, and Industrial Processing. With a strong focus on providing flow solutions to the industrial sector to reduce carbon footprint and preserve natural environments, AW-Lake produces one of the most comprehensive portfolios of flow measurement technologies in the US.
