General
The controller operates in a stable control range starting at the minimum response pressure, which is a function of the volume flow, up to a maximum pressure difference of 1,500 Pa.
The volume flow deviation is low across the entire pressure range. The effective volume flow and deviations depend on the controller type and must be clarified prior to ordering.
Flow velocity is between 1 m/s and 8 m/s for adequate response sensitivity and control precision.
Wiring
Insulate all wiring to the available rated voltage. Sizing and fusing of the wiring is based on the connected load.
Measuring tubes on the volume flow controller
One red and one blue measuring tube (each 2.5 meters in length) are included with the volume flow controller. The measuring tubes can be shortened as needed. There are two pneumatic push-in fittings on the volume flow controller. The first pressure connector in the flow is for positive pressure (red tube). Protect the tube fittings during transport and installation. Ensure that the fittings are properly seated. Pneumatic push-in fittings are recommended to extend the length of the tubes.
