Cole Parmer offers an extensive range of turbine flow meters for both liquid and gas applications. There are many types of turbine flow meters, some offer low cost water meter solutions with accuracy typically around 3% full scale, while other turbine flowmeters offer high accuracy of 1% or better.
Cole-Parmer's turbine flow meter selection encompasses a wide range of materials including low cost nylon and aluminium bodies to specialty options such as PVDF or stainless steel for more aggressive, higher temperature applications. Many of our turbine flowmeters come with a wide range of digital displays and controllers including options for PC, PLC control or batch dispensing operation.
How a Turbine Flowmeter Works
This mechanism includes a bladed rotor that is positioned along the centerline of the flow stream. The rotating component is designed to provide a pulse when passing either a magnetic or optical sensor. The frequency of the pulses is proportional to the velocity of the fluid. Some designs offer high levels of accuracy and can often handle slightly higher viscosity fluids than basic propeller-type designs. Some turbine designs meet sanitary guidelines (where stipulated by the manufacturer).
Typical Applications for turbine flow meters
- Pilot plants
- Research and development facilities
- Cooling water monitoring
- Inventory control metering applications
- Test stands
- Water consumption
- Makeup water
Advantages for turbine flow meters
- High accuracy and good repeatability
- Fast response timetypically a few milliseconds
- Wide flow range options for both liquids and gases
- Good flexibility with associated digital readout devices including flow control options for both PC and PLC's
Disadvantages for turbine flow meters
- Require upstream straightener and filter for best results
- May over-read in pulsating flows
- Turbine flow meters for liquid can require regular re-calibration due to bearing wear
- Particulates can cause line blockage
