Mechanical Flowmeter MF 315

  • A simple and reliable, impeller driven instrument used to determine the flowing speed of a variety of moving flulds.
  • Mechanical odometer displays total impeller revolutions in an adjustable time period. The calibration chart, provided, converts counts to velocity or
  • distance.
  • High accuracy.readings due to its ability to self align with the fluid flow. The pivoting axle located at the balance center, facilitates orientation
  • with the flow along the in-situ gravitational line.
  • Free flooding capacity allows for usage at any depth.
  • Double-point, flexible, connection for use with plankton nets or other plankton collecting equipment.
  • Rigid pivoting axle for mounting on fixed support
  • Manufactured entirely from corrosion resistant materials.

Mechanical Flowmeter MF 315


Electronic Flowmeter EF 325

Description:

  • Same measuring principle, materials, overall configuration and use as the mechanical flowmeter Model MF 315.
  • Features a LCD display mounted on a battery operated integrated circuit board, that gives total impeller rotations enabling flow speed calculation.
  • On/Off switch and reset capabilities.
  • The LCD is activated for 10 seconds at a time
  • Records one way only thereby prolonging the battery life.
  • More accurate than the mechanical flowmeter due to less moving parts.
  • Practically maintenance free being a self contained chamber
