SEBA-Mini Current Meter M1 serves for determination of the current
velocities in laboratories, river models, brooks, small rivers with low
water level and for tubes with small diameters. Special advance:
universal application; low starting speed; frictionless contact
transmission; non-corrosive materials; unit composed system. Meterbody:
The streamlined meterbody is made of high-quality non-corrosive steel.
shaft moves in 2 extremely smooth running precision ballbearings. The
oil filling and a capillary seal protects it against water entry. The
propellers with high pitch accuracy are manufactured from
seawater-resistent and anodized aluminium. They only will be put on and
can be exchanged quickly.
transmission One signal is generated from each revolution of the
propeller. The reedswitch for transmission of the propeller revolutions
is composed within a small metal tube to a miniature construction unit.
The counting frequency for the mechanical counter Z1 is limited to 10
impulses per second. By application of the electronical counter Z4 all
flow velocities can be measured. A complete current meter equipment
comprises 6 propellers with 50 mm Ø resp. 30 mm Ø with diverse pitches .
on the requirement, the equipment can also be delivered with single
propellers. Guiding device Generally a measurement will be effected on
rod 9 mm Ø. This rod is manufactured from non-corrosive steel, in 3
parts and has a total length of 1,5 m. A base plate for the rod is
attached. On request a cm-division and a dmgraduation of the rod is
possible. For measurements on rod 20 mm Ø resp. with relocating device, a
special clamp is available.
