This impeller turbine flowmeter is designed for measuring flow rates up to 100 m3/h with an accuracy of plus or minus 0.5%. It suits a range of media including gas oil, kerosene, diesel, water, and methanol, making it a practical choice for workshops, fuel management, and industrial fluid monitoring. The 25 mm nominal diameter and screw-to-PT end connections allow straightforward installation into existing pipework. With a working pressure of 0.3 MPa and normal working temperature, it covers common low-pressure applications. The body is made from aluminium alloy, available in blue or red, and alternative versions include plastic or stainless steel. This flowmeter provides a reliable way to track flow without overcomplicating the setup.

25mm Turbine Flowmeter 0.5% Accuracy 100 m3/h Aluminium Alloy

Features and Construction

Material and Build
The standard body is made from aluminium alloy, which keeps the unit relatively light while handling the stated working pressure of 0.3 MPa. Blue and red colour options are available, and there are also plastic and stainless steel variants. The impeller mechanism is suited to the listed media, and the screw-to-PT two-end interface ensures a standard connection type.Size and Practical Fit
The nominal diameter is 25 mm, a common size for small to medium pipework. The measuring range reaches 100 m3/h, and accuracy is plus or minus 0.5%. These figures help determine whether the flowmeter matches the expected flow rates in an existing system. The screw-to-PT interface allows direct fitting without special adapters in many cases.Uses and Placement

Event or Professional Use
In professional settings, this turbine flowmeter can monitor diesel or kerosene flow in fuel depots, generator refuelling, or fleet management. The 100 m3/h range and 0.5% accuracy support tasks where consistent measurement is needed. The aluminium alloy body is suited to normal temperature and 0.3 MPa working pressure.Everyday Home Use
For home workshops or small holdings, the flowmeter can measure water or methanol flow where a 25 mm line is present. The screw-to-PT connections make it compatible with common fittings. Use only with the listed media and within the stated pressure and temperature limits.Benefits and Buying Value

Reuse and Low Maintenance
The aluminium alloy or stainless steel versions can be reused across compatible fluid systems, provided they are kept within the stated operating limits. The impeller design has no external moving parts beyond the internal rotor, which simplifies inspection. Routine checks for debris and correct installation help maintain accuracy.Why Choose This Product
Choose this flowmeter when you need a 25 mm device with a 100 m3/h range and 0.5% accuracy for diesel, water, methanol, kerosene, or gas oil. The availability of blue and red colours, plus alternative materials, allows matching to specific setups. It is a straightforward measurement tool for normal-temperature, low-pressure applications.
