Flow Meters
Accurate measurement for fuel, water, chemicals, gas and steam.
Ten meters across five measuring principles — oval gear, turbine, electromagnetic, ultrasonic and vortex — in mechanical and digital versions, threaded or flanged, with pulse, 4–20 mA and RS-485 output options.

| Principle | Accuracy | Best suited to | Line sizes |
|---|---|---|---|
| Oval gear → | ±0.1 to ±1.0% | Fuel, oil, viscous liquids to approx. 1,000 cP | 1/4–3″ |
| Turbine → | ±1 to ±2% | Clean, low-viscosity liquids — water, fuel, chemicals | 1/2–4″ |
| Electromagnetic → | ±0.5 to ±1.0% | Conductive liquids — water, waste water, hygienic media | 1/2–10″ |
| Ultrasonic → | Approx. ±1 to ±2% | Surveys and temporary metering, no pipe cutting | DN15–DN6000 |
| Vortex → | ±0.5 to ±1.0% | Steam, gas, air, high temperature | 1/2–4″ |
Oval gear meters · fuel and oil
Positive displacement — the most accurate choice for viscous and non-conductive fluids.
High-pressure digital oval gear →
Rated to 50 bar (250 bar in stainless on request). ±0.1% accuracy, pulse output, sizes 1/4–3″ BSP.
Digital oval gear fuel meter →
Digital display with resettable totaliser. 25–300 L/min, viscosity to 1,000 cP, sizes 1–2″ BSP.
Mechanical oval gear fuel meter →
No power needed — suits remote and hazardous areas. 0.5% accuracy, −40 to 80 °C, sizes 1–2″ BSP.
Flanged mechanical oval gear →
Heavy duty for tanker loading. Mechanical counter, optional pulse, cast iron to stainless, 1–3″ flanged.
Turbine meters · clean liquids
A spinning rotor generates a signal proportional to flow — best on clean, low-viscosity liquids.
Inline turbine flow meter →
Stainless steel, −20 to 120 °C. Battery display, 4–20 mA or RS-485. Flameproof and IP-65 options, 1/2–4″ flanged.
Compact digital turbine fuel meter →
Portable dispensing, 10–90 L/min. Battery powered, switchable units, aluminium body, 1–2″ BSP.
Battery-powered chemical meter →
Urea solution (DEF), methanol and chemical liquids. 10–120 L/min, ~2 years standby, 1/2–1″ BSP.
Electromagnetic meters · water and process
No moving parts, no obstruction — no pressure drop and nothing to wear out.
Electromagnetic flow meter →
Water, waste water, slurries and hygienic liquids. Pulse, 4–20 mA, alarm and RS-485. IP65, 1/2–10″ flanged.
Ultrasonic meters · surveys and spot checks
Clamps onto the outside of the pipe — no cutting, no shutdown.
Portable clamp-on ultrasonic →
Pipes DN15–DN6000, most materials. Built-in data logger, MODBUS, bi-directional. Ideal for verifying installed meters.
Vortex meters · steam, gas and air
No moving parts and a very high temperature rating — the standard choice for steam.
Vortex flow meter →
Up to 350 °C and 60 bar. Saturated and superheated steam, compressed air, gas and liquids. Optional P/T compensation.
