Selecting the Right Flow Sensor for Your Task
Measuring Liquid flow with Almemo®
Flow Measurement – The Almemo Way
When measuring flows using ALMEMO® sensors, the ALMEMO® instruments provide important data functions for averaging (over time or over single measurements) and for volume flow measurement (width, length, diameter, cross sectional area of the ventilating channel). For Pitot tube measurements the temperature influence can be automatically compensated. Please ask for our detailed ALMEMO® Manual. It will provide you with valuable tips and a detailed description regarding flow measurements using ALMEMO® equipment.
SENSOR TYPE | FLOW VELOCITIES | OPERATING TEMPERATURES |

Axial Turbine | ||
Pressure pulsation |
Axial Turbine
The water flow is measued by a turbine within the pipe, this turbine is fitted with permant magents which a hall effect sensor picks up.
Pitot tubes are robust and available in special steel or nickel-plated brass. They connect to ALMEMO® devices by silicone hoses and a differential pressure module.
Advantages
Suitable for small flow rates, compact design
Disadvantages
Directional,
Pressure Pulsation
The flow rate is determinted by the Kármán vortex street principle.
Our rotating vanes are sensitive transducers with diamond bearings that are very precisely adjusted. This ensures high accuracy.
Advantages
Low pressure loss, wide temperature range, high-speed reaction time
Disadvantages
Directional
A range of VA flow meters suitable for Air or Water
We cover a wide range of air flow meters from 0.04LPM right up to 11,000LPM and water from 5CCM up to 400LPM.
