Duct air flow meter overview

SRK-100 series thermal dispersion flow meter is perfect for HVAC duct air flow measurement in large ducts, pipes, hoods, stacks. It could be round, square, and rectangular shape ducks. The gas can be vent gas, stack gas or digester gas. We sell low price air velocity flow transmitters as duct mounted air flow meter. Air velocity in ducts usually has small flow rate to decrease the noise or energy consumption, low flow air duct flow indicator is demanding in ductwork air flow measurement. Air Low velocity is vital for the energy efficiency of the air distribution system. Welcome to buy low price duct air flow meter from reliable China flow meter factory.

Features of duct air flow meter

  • Stainless steel flow meter for wind velocity instrument with 316L wet parts material
  • No moving parts in the air flow sensor is suitable for rugged industrial environments, long-term stability
  • Thermal dissipation probe can detect low air flow rate still with good accuracy
  • Detect air velocity even micro air flow rate at fast response
  • Wide range detect, turn down ratio: 1: 100, it can detect 0.5~ 120 Nm/s flow rate
  • No temperature and pressure sensor needed to calculate the air mass flow with flow unit Nm3/h, SCFM, SLM
  • Insertion air flow sensor for HVAC duct air flow measurement
  • Digital ductwork air flow indicator with display to show totalizing flow and instate flow
  • No zero shifting for duct mounted air flow meter
  • RS-485 communication, option with HART
