CURRENT METER Features: Extremely robust current meter for all flow velocities Made of high quality non corrosive steel Nearly wattless and frictionless contact making Modular system Operation possible on rod or as suspended current meter at SEBA-cable way installation, measurement trailer, measurement car or with mobile bridge jib For mobile velocity measurements, especially suitable for: waters with problems of fouling by weed or dirt, sewage channels, waters with extremely low or high current velocity The SEBA - Universal Current Meter F1 serves for determination of current velocities in water courses, canals, rivers and the sea, for use with rods or as cable-suspended meter equipment from 0, 025 m/ s up to 10. The SEBA-Universal Current Meter F1 serves for use on rods as well as for cable-suspended- current meter equipments for use with SEBA single drum winches or cable way installations.The streamlined meterbody and the axle are manufactured of high-quality, non-corrosive steel. The hub of the propeller is filled with oil and rotating in two special ball-bearings. The oil filling and a capillary seal protects against water entry. A base stop prevents the propeller from striking the ground. One signal is generated from each revolution of the propeller by means of a permanent magnet. Frictionless operation increases the sensitivity of the instrument. The contact mechanism is quickly interchangeable without problems. Instrument case Robust version made of aluminium, lockable, with three cover hinges, cover- and base plate made of resistent black ABS plastic. Dimensions: standard with compartment for counter 465 x 340 x 140 mm. Weight: case including equipment approx. 6 kg.
