The Kele KMS2 Series airflow measurement station comprises single or multiple airflow elements, pre-assembled and pre-piped within a casing designed for flanged ductwork connection. It may also include an airflow straightening section, crafted from aluminum honeycomb with a ½ inch opening and 3 inch depth. Standard materials consist of a G90 galvanized casing, 6063-T5 anodized aluminum flow sensors, and an optional 3003 aluminum airflow straightener. Total pressures sensed by upstream ports are continually averaged within an isolated chamber, while static sensing ports, located where velocity head influence is zero, are averaged in a second isolation chamber. Multiple elements are manifolded together for connection to a differential measurement device, enabling flow measurement and indication. Kele, a leading building automation products supplier, ensures you get the right product when you need it. Element spans multiple total and static pressure sensing ports Pre-assembled in a flanged duct casing with factory-mounted piping Optional: Honeycomb airflow straightener for improved accuracy ±2% precision from 100 to 800 FPM Galvanized casing and aluminum flow sensors for durability Operates up to 350°F Functions in 0 to 100% humidity conditions Standard stations resist salt air and suit most HVAC uses Brand Name Kele Item Weight 0.6 Pounds Manufacturer Kele Material Type Galvanized Steel, Aluminum Warranty Description 1 year
