The OSSPC1 miniature current meter is a field-proven instrument for measuring the velocity of water in shallow open and closed channels. It is used for point measurements of flow velocities on the water surface or in vertical profiles down to the riverbed at flow speeds of 0.025 m/s to 6 m/s.

The OSSPC1 body is made from corrosion-resistant nickel silver with anodised aluminium fans. It is suitable for use in the most  and has been designed for lifetime trouble-free operation under normal use and when properly maintained.

KISTERS’ current meters are modular systems: You can tailor the perfect solution for your application with a choice of several fans, rods, accessories, etc.

The full range of equipment needed for successful stream gauging is available from KISTERS. Please contact us for advice!

Alternative Model for Deeper Waters

The KISTERS universal current meter OSSB1 is used for point measurements of flow velocities on the water surface or in vertical profiles down to the riverbed at flow speeds of 0.025 m/s to 10 m/s. Deployment: mounted on wading rod, from a bridge/boat using winches and outriggers, or on cableways.

  • Corrosion-resistancy: 
    • Body: nickel silver
    • Fans: anodised aluminium
  • Precise and reliable measurements:
  • Encapsulated magnetic reed switch ensuring reliability and a ‘clean’ contact signal
  • Direct results: Direct display of velocity or number of revolutions with KISTERS’ counters or the paperless stream gauging tablet 
  • Easy deployment on standard wading rods (supplied with standard kit) and top set wading rods

The streamlined and robust assembly of body and fan makes the OSSPC1 especially suitable for

  • water velocity measurements,
  • stream gauging, and
  • discharge measurement in shallow water. Thanks to its low start velocity of only 0.025 m/s, the OSSPC1 shows correct results even in very slowly flowing channels.
