Eco Up/Down (U/D) Probes are single probes used as an economic way to monitor or measure airflow within HVAC ductwork systems where other flow rate measuring devices are found to be unsatisfactory, difficult to install or exceed the budget. They can be fitted to either rectangular, square or round ductwork up to 600mm across.

Eco U/D Probes consist of one precision machined aluminium extrusion mounted through the cross section of the duct and are easy to install and maintain. One set of holes face upstream and the other set face downstream. The signal generated is an average signal for both the total and sub-static pressures.

The machined aluminium probe makes the Eco U/D Probe a very economically priced product without compromising on the quality or accuracy. Although not offering quite the same level of accuracy as the Eco Radial Flowgrid, the Eco U/D Probes are ideal for secondary and some primary volume flow control systems.
