BES Flowmeters supplies high-accuracy turbine flow meters for industrial liquid measurement — including the BES Turbo IR, Flomec G2 series and GPI turbine meters. Turbine flow meters are the preferred choice for water, fuel, chemical and process liquid applications requiring proven accuracy, wide turndown and fast response.
How Turbine Flow Meters Work
A turbine flow meter places a multi-blade rotor in the flow path. As liquid flows through, the rotor spins at a velocity proportional to flow rate. Rotational speed is detected by a magnetic or optical pickup and converted to a flow reading. Turbine meters typically deliver ±0.5% accuracy or better, making them well-suited to custody transfer, batch control and process monitoring.
BES Turbo IR — Turbine Water Meter
The BES Turbo IR is BES Flowmeters' own-brand turbine water meter, designed specifically for Australian water measurement applications:
- Infrared (IR) pulse output — no reed switch, no moving electrical contacts, long service life
- Sizes 15mm to 100mm (½" to 4")
- Suitable for cold potable water, irrigation and industrial water measurement
- High accuracy ±2% of reading
- Compatible with BES rate/totaliser displays and batch controllers
- WRAS-approved materials for potable water contact

Frequently Asked Questions
A turbine flow meter measures flow by passing fluid through a rotor with angled blades. The rotor spins at a speed proportional to the flow velocity, and a sensor detects each blade pass to generate a frequency signal. The BES Turbo IR range uses infrared detection for reliable performance without the electrical interference issues of magnetic pick-up designs.
Turbine flow meters are best suited to clean, low-viscosity liquids such as water, light oils and chemical solutions. They are not recommended for fluids containing suspended solids or high-viscosity liquids that may damage the rotor. For those applications, electromagnetic or positive displacement meters are a better choice.
The BES Turbo IR is a turbine flow meter designed and manufactured for the Australian market. It uses infrared pulse detection rather than magnetic sensors, eliminating signal interference in electrically noisy environments. The Turbo IR is widely used in water, irrigation and light industrial applications.
Turbine flow meters typically achieve accuracy of ±1% or better when operating within their specified flow range. The BES Turbo IR is calibrated and tested before despatch. Accuracy is maintained provided the meter is correctly sized and installed with adequate straight pipe runs upstream and downstream.
Yes — turbine flow meters require a minimum length of straight pipe upstream (typically 10x pipe diameter) and downstream (5x pipe diameter) of the meter to ensure accurate measurement. This minimises flow disturbances from valves, bends and fittings. BES Flowmeters can advise on installation requirements for your specific application.
