Dwyer® AVUL Series Air Velocity Transmitter quickly and accurately measures air velocity or volumetric flow in imperial or metric units. Simultaneous current and voltage outputs on all models provide universal inputs to monitoring equipment while the output range, units, and 0 to 5/10 VDC output can be configured via local DIP switches.
• Sensing components have been covered with a built conformal covering to guarantee solidness and life span.
• Field selectable extents can be immediately arranged without the capacity to the unit.
