The flow meters of the D series by Ateq exploit the precise and clean air laminar flow technology. They can be used in manual or automated testing stations, with the following technical specifications: D520 represents the most compact, versatile and performing execution, ideal for use in automated lines, installed very close to the measuring point to optimize the test; D535 is instead suitable for flow rate measuring in manual workstations. In the latter case the pneumatic unit can be installed close to the measuring point, improving testing results (the control terminal can be instead positioned next to the operator, thus facilitating its management). Flow rate measurements range from 1 l/h up to 10,000 l/h; in special version, even up to 65,000 l/h.
