Home › Flow Meters › Turbine Flow Meters
A turbine flow meter spins a bladed rotor in the flow and counts the pulses; the rate sets the speed, so the pulse frequency tracks the flow. It is an accurate, low-cost choice for clean, low-viscosity liquids and gas. Instranova builds inline and cryogenic versions; pick by the medium and the temperature, then open the page for specifications.
Our turbine flow meters
The inline LWGY covers water, fuel, solvents and gas; the cryogenic build handles liquid nitrogen and other liquefied gases down to deep cold.
Turbine Flow Meter (LWGY)Inline meter for clean liquids and gas, DN4 to DN200.
Sanitary Turbine Flow Meter316L tri-clamp for food, beverage and pharma; DN4 to DN50, CIP to 180 C, to 0.2% FS.
Insertion Turbine Flow MeterProbe into a large pipe by hot tap; meters a big main at low cost, to plus or minus 2.5%.
Gas Turbine Flow MeterFor natural gas and clean gases; built-in flow computer to standard volume, DN50 to DN300.
Cryogenic Turbine Flow MeterUltra-low-temperature build for LN2, LOX and LNG: minus 196 C rotor, DN6 to DN100, 0.5% of reading.

Choosing a turbine flow meter
Start with the medium and its temperature; both versions need clean, low-viscosity flow.
| Your medium | Pick | Why |
|---|---|---|
| Water, fuel, solvent or gas at ambient or warm temperature | LWGY inline | Stainless body, pulse or 4-20 mA, DN4-DN200 |
| Liquid nitrogen or other liquefied gas at deep cold | Cryogenic turbine | Built for low temperature and rapid response |
For dirty, viscous or pulsating flow a turbine wears and drifts; in those cases an electromagnetic or vortex meter fits better. Browse the full flow meter range to compare methods.
Every meter in this series ships with its K-factor stated on the calibration certificate. The flow meter K-factor guide explains how to enter that number in a totalizer, verify it in the field, and correct it when a proving run disagrees.
FAQ
Are turbine flow meters accurate?
Yes, on the right media. A turbine meter holds plus or minus 0.5% of reading as standard and plus or minus 0.2% on a calibrated build, across a 10:1 to 20:1 turndown. Accuracy depends on a clean, steady, full flow and enough straight pipe; debris, heavy viscosity, swirl or pulsation degrade it.
