LY-3062 Duct Flow Velocity Monitor is a professional duct gas measuring instrument designed based on the Pitot tube flowmeter principle. It can accurately measure the cross-sectional average flow velocity and synchronously display duct dynamic pressure, static pressure, total pressure, temperature, flow velocity and flow rate. The whole machine adopts Ex ib IIB T4 Gb explosion-proof design, which can work safely in conventional and flammable & explosive hazardous environments. It supports USB data export, Bluetooth printing, built-in explosion-proof lithium battery for long-time operation, widely used in oil depots, chemical industry, mines, industrial pipelines and other occasions.
Adopts standard Pitot tube measurement principle to accurately measure duct cross-sectional average flow velocity with high stability and good repeatability.
Full explosion-proof structure, certified Ex ib IIB T4 Gb, safe for use in flammable, explosive and dangerous gas environments.
Real-time display of dynamic pressure, static pressure, total pressure, temperature, flow velocity and flow rate, one machine completes multi-index detection.
Pressure tapping tube supports switching of different lengths to adapt to various duct sizes and working conditions.
Equipped with USB port for data file export; built-in Bluetooth module can connect to portable printer for on-site data printing.
Built-in 7.4V explosion-proof lithium battery, continuous working time ≥24 hours, lightweight host, easy for on-site mobile detection.
