Description
DK 700 Miniature flowmeters
with fine-adjusting needle valves
ideal for analytical processes
A new-style valve design allows the proportioning of ultra-low flow rates with an approximately linear control characteristic. The instrument is easy to install in switch
panels. Clamp clip attachment on the rear of the instrument.
In place of a scale on the measuring glass, types DK 701 and DK 711 have a scale in yellow print on a black face-plate.
Types DK 702 and DK 712 feature a scale on the measuring glass and a face-plate of polycarbonate without a scale.
Special version with a plastic valve made of PEEK mod material and gaskets of TFM/Kalrez; accordingly, all wetted parts are made of materials that are highly esistant to chemical attack.
