Selection of the correct FT series model is determined by the specific need for battery power (FT450), 4-20mA loop power (FT440), or standard external power (FT430).
Seametrics FT430 (P/W) Rate/Total Indicator are microcontroller-based flow computers designed to process data from pulse output flow sensors. The choice between models depends on power and output requirements: the FT450 is ideal for internal battery-powered applications, the FT440 is designed for 4-20mA loop-powered systems, and the FT430 is suitable for standard external power source.
Seametrics, a member of the TASI Flow Group, is a designer and manufacturer of a variety of flow metering and submersible sensor products. Since 1990, we have provided innovative solutions to users in irrigation, fracking, water & wastewater, environmental, and processing applications. Our products have a reputation for durability and accuracy at a competitive price and are sold through our network of domestic and international distributors.
Located just south of Seattle, our Kent, WA factory is home to both our engineering and production groups. We employ just-in-time manufacturing methods and have a high commitment to continuous improvement as demonstrated by our ISO 9001 quality management system. Our focus on innovation, product value and customer accessibility has resulted in over two decades of continuous growth. Seametrics is dedicated to helping conserve the world’s most valuable resource by providing our customers with precision flow meter and environmental sensor products.
