Positive displacement flow-meter for viscous liquids
5 - 80 l /min, max . 10 bar | VKG
KOBOLD INSTRUMENTATION
Description
The KOBOLD flow meters and switches model VKG have a
spring-loaded float, which slides within a cylindrical measu-
ring tube and has an integral orifice which is believed to be
unique.
This and other design features means that it has for the first
time become possible to create a flow meter and switch
which fully compensates for viscosity and to a large extent for
density even with very low flows. The float of these patented
devices contain permanent magnets which actuate a poten-
tial free bistable reed contact mounted outside the flow thus
ensuring hermetic separation between the medium and the
electrical contact system. The contact is embedded within a
height-adjustable plastic housing to prevent damage to the
contacts by mechanical action or aggressive atmospheres.
