Kobold Turbine Flow Meter

• Kobold DRS Turbine Wheel Flow Meter/Monitor :
  • KOBOLD model DRS flowmeters are used for measuring and monitoring liquids. Due to its compact construction the mini turbine is suitable for use with machines with minimum available space.
• Kobold TUR Turbine Wheel
  • The flowmeters with turbine wheel serve to measure, control and regulate flowing liquids. The use of chemically highly resistant materials allows the devices to be used with acids, bases and aggressive media that are to be found in the chemical industry.
  • There are four kinds of TUR turbine wheel, such as: TUR-1, TUR-2..M, TUR-2..C3, TUR 2..K
• Kobold DPE Turbine Wheel Flow Meter
  • The KOBOLD flow meter model DPE is used for measuring and monitoring liquids. The device works according the well-known blade wheel principle.
  • The six vane blade wheel is retained axially in a high quality sapphire bearing. The sensor is supplied ready-to-install with pipe fittings or with weld-on sleeves.
  • The blade wheel is set in motion by the flowing medium. Magnets are embedded hermetically sealed in the ends of the blade wheels. The magnets generate electrical pulses in a Hall effect sensor mounted outside the flow area.
• Kobold DRB Turbine Wheel Flowmeter
  • The KOBOLD flowmeter model DRB is used for measuring and monitoring liquids. The device works according the well-known blade wheel principle. The four vane blade wheel is retained radially in a high quality sapphire bearing.
  • The sensor is supplied ready-to-install with pipe fittings or with weld-on sleeves. The blade wheel is set in motion by the flowing medium. Magnets are embedded hermetically sealed in the ends of the blade wheels.
  • The magnets generate electrical pulses in a Halleffect sensor mounted outside the flow area. Various electronics units can be used to display and monitor the volumetric flow.
• Kobold TUV Turbine Wheel Flowmeter
  • The TUV model turbines are based on the principle of the Woltmann rotating vane meter. A turbine wheel of negligible mass is concentrically mounted in a pipe and supported by bearings.
  • The liquid flows through the turbine wheel in the axial direction. The medium flow is smoothed by a flow straightener, and reaches the turbine wheel as a quasi-laminar flow stream.
  • The speed of the turbine wheel is proportional to the average flow velocity across the pipe cross-section. The rotational speed is thus proportional to the volumetric flow over a wide range.
  • An inductive transducer screwed into the turbine housing senses the speed of the turbine wheel in a non-contacting manner.
  • The sensor signal is amplified and converted to produce a pulse signal. The pulse count per time unit is proportional to the actual flow rate.
  • All turbines are calibrated and delivered with their own calibration reports, Variations in viscosities in your application can be taken into consideration during calibration of the most commonly found viscosities.
• Kobold SFL Low Volume Turbine Wheel Flowmeter :
  • The model SFL low volume flow meter is particularly suitable for service with liquids free from solids.
  • The liquids must be transmissive for infrared light (for example: water, oil, chemicals).The plastic or stainless steel material combination allows service with aggressive media.
• Kobold DOT Turbine Wheel Flowmeter/Monitor :
  • The turbine flowmeter model DOT consists of a helically shaped turbine rotor supported in two tungsten carbide bearings, the rotor being solid ferritic stainless steel of a grade compatible with the metered liquid, all contained within a housing of non-magnetic stainless steel.
  • A pick off coil having a permanent magnet core is mounted in the housing adjacent to the rotor blade tips such that a magnetic circuit is set up via the rotor blades.
  • Rotation of the rotor varies the reluctance of this magnetic circuit and the flux changes induce a small voltage in the coil, the frequency of which is directly proportional to the rotor speed and therefore proportional to the volumetric flow rate.
  • The effects of increasing viscosity reduce the linear flow range and  shifts the k-factor. Further, the effect of viscosity depends on the frequency (RPM of rotors). Therefore, smaller the meter, higher is the effect of viscosity on the linearity curve.
• Kobold PEL-L Turbine Wheel-Low Volume
  • The sensor principle based on a Pelton water wheel is remarkable for its high reliability – proven over more than ten years of service.
