Model HM-R - Turbine Flow Meters
From Turbine Flow Meters
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…R turbines have inch sized female threads allowing a great variety of connections.
Specification
- Measuring range: 0.03 bis 400 l/min
- Viskosity: 0.1 up to 100 mm²/s
- Linearity: ±0.5 % of actual value
- Pressure: bis 630 bar
- Fluid temperature: –273 bis +350 °C
Advantages
- Fast respone time and high resolution
The turbinewheel’s 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.
