Turbine Flow Meters with Ermeto Fittings (HM-E)

Turbine Flow Meters with Ermeto Fittings (HM-E)

Turbine Flow Meters for the precise measurement of instantaneous flow rates and flow quantities of low-viscosity fluids as tap and demineralised water, fuels, liquefied gases, solvents, light fuel oil and pharmaceutical fluids.

HM...E turbines are equipped with Ermeto fittings.

  • Measuring range: 0.3 up to 500 l/min
  • Viskosity: 0.1 bis 100 mm²/s
  • Linearity: ±0.5 % of actual value
  • Pressure: bis 630 bar
  • Fluid temperature:–273 up to +350 °C

Fast respone time and high resolution
The turbinewheels low moment of inertia allows a fast acceleration from standstill up to full number of revolutions within 5 to 50 msec. For that reason dynamic measurements can be done. The resolultion can amount to as much as 139,000 pulses per litre.

  • Wide temperature range from –273 up to +350 °C
  • Standard turbine flow meters: -20 up to +120 °C
  • Special models for cryogenic liquids: - 273 °C
  • Special models with high temperature pickups: up to +350 °C

Low contamination risk:
The spacing of the turbinewheel and bearing mount is wide enough to protect against particles in fluid jamming the turbinewheel. Furthermore the twist of flow in this area has a self-cleaning effect for the bearing.
