Acoustic duct flow and flow sections

sFlow

sFlow is a flow meter for air and gasses under atmospheric conditions.

Ranges from 0.004 m³/h up to 400,000 m³  
(0.002 ft³/min up to 235,000 ft³/min)
(from leakage detection to industrial process measurements).

Models

• Stationary applications for different standard pipe diameters and duct sizes
• Mobile devices as handheld apparatus e.g. to be used for energy performance index measurements, welding vapour hood, ventilation grids etc.
• Integrated solutions for measurement and control of flow in production environments
• Applicable to e.g. inline test units for heat recovery units, air handling units, fume hoods, food industry, pig and poultry houses.

Features

• No obstructions in duct or channel
• No back pressure compensation needed to obtain the correct accuracy
• Full range from zero within one configuration without additional adjustments
• Flow section easy to implement in current configurations and installations
• Suitable for fan applications from very low power up to 250 kW.

Implementation

• Flow section with one or more acoustic measurement lines
• Sections with or without flange
• Additional sensors and process control possibilities
• Several flow sections can be used in one electronic unit
• Mobile version expandable with datalogging on SD memory
• Industrial interfacing, optional with measuring software
• Special implementations insensitive to dust.
