4. Regulation
Use
These units, type SWK, are used for the purpose of measuring and monitoring
liquid flow. Only clean, low-viscous and homogeneous liquids may be measured
which do not chemically attack the materials used in the construction of these
units. An attempt to measure high-viscous liquids may lead to considerable
measurement errors.
Large dirt-particles can cause the blockage of float and subsequently turn on
error indications. Also, ferrite particles, which deposit on float (with embedded
magnets), can generate the same effect (we recommend a magnet-filter).
These units are configured in the following manner:
Housing made of Brass, St. Steel or PVC
Attached reed contact N/O with 1m PVC cable (Brass version)
Attached reed contact N/O with 2m PVC cable (PVC/VA version)
Attached and aligned pointer display (option)
5. Operating
Principle
KOBOLD Flow Meter/Monitor of type SWK operates according to the well known
float principle, however without making use of the generally employed extended
measuring tube. Inside a cylindrical flow-tube a float with aperture moves in the
direction of the flow against the recoiling force of a spring. Within the float, a pair
of magnets is located which trigger a potential-free protective-gas reed contact
and drives a pointer display. The reed contact is mounted on the exterior of the
flow-housing. The springs arrangement allows the unit to be operated without
consideration to mounting position and keeps the installation dimensions to a
minimum. Flow monitors of type SWK generally find application where small
volume flow needs to be measured in a fail-safe manner.
