Perfectly adapted for control and regulation of reagent in flue gas treatment and transport lines with very low material concentration
Electrodynamic flow sensor for measurement of low flow rates.
For pipe diameters up to 1 m.
Ideally used in leanphase conveying.
In free fall conditions with at least 2 m/s drop speed.

| The PicoFlow can be installed in metallic ducts and pipelines.
It should be installed as far as possible away from curves and other fittings such as valves and slides. The distance between the sensor rod and fittings in the duct should be at least three times the duct diameter in every flow direction. Non-metallic ducts must be cased with a metal sleeve, a metal foil or a tight-mesh metal grille over a length of at least five times the duct diameter. |
