Many buildings are designed with confined areas for mechanical equipment which often result in restricted spaces for duct systems and very uneven velocity contours. The 863 is a perfect solution.
Diamond Shaped Sensor
A flow sensor which will average uneven velocities as well as accurately read very low flow rates will play a larger role in the design of critical systems.
Current technologies for low flow sensing are primarily based on a probe design but uneven flow contours will often pass above or below the probe resulting in undependable flow readings. Our solution is to use a proven averaging sensor with a very accurate transmitter and a post conditioning circuit to accurately read very low flow rates.
The Waddell Diamond Shaped Sensor is available in all aluminum or stainless steel constructions. There are 8 available sizes from 4” up to 18” and include flow ranges from 28 cfm to 3900 cfm.
