Quick Answer: Turbine flowmeter hubs are the rotor modules that spin inside a turbine flow meter. They convert fuel flow into a pulse signal for gasoline, diesel, jet fuel, and light oil lines. Silver Automation Instruments supplies replacement hubs and complete turbine flow meters in DN10 to DN50.
Turbine flowmeter hubs sit inside the meter body. Fuel enters the inlet. The rotor blades turn. A magnetic pickup or RF sensor counts each blade pass. The pulse frequency is proportional to flow rate. This output is fast and easy to connect to PLC, batch controller, or fuel management system.
The hub contains a rotor with helical blades. Fuel pushes the rotor. The rotor speed tracks flow velocity. A sensor detects each blade pass. The output frequency equals volume flow. This method works well for clean fuel with viscosity from 0.5 cP to 5 cP.
In practice, diesel at 20 °C has viscosity around 2.5 to 5 cP. Gasoline is lower. Jet fuel sits within the same range. Turbine hubs respond quickly in these fuels. But solids or wax can damage the bearing. Use a strainer before the meter.
Silver Automation Instruments offers turbine flowmeter hubs with 316 stainless steel or aluminum bodies. Rotor blades are machined from stainless steel or a special polymer. Bearings are tungsten carbide or ceramic. Typical sizes are DN10, DN15, DN20, DN25, DN32, DN40, and DN50. Pressure ratings reach 400 bar. Medium temperature range is -40 °C to 120 °C. Accuracy is ±0.5% of reading. Repeatability is ±0.05%.
Output options include pulse, 4-20 mA, and 4-20 mA HART. Fuel skid builders often use pulse output for batching. Service teams prefer HART for remote diagnostics. Both signal types work with standard flow computers and PLCs.
A replacement hub is a low-cost option when the meter body and pickup are still good. You can order a new hub assembly. Send us the meter serial number, size, flow range, fuel type, and bearing material. We match the hub to the original meter.
If the meter body is worn or the sensor is damaged, install a complete turbine flowmeter. It is often faster. We have seen customers in Australia and Vietnam replace hubs on diesel engine test stands. The swap takes less than 30 minutes on site.
Gasoline loading racks, aviation fuel test kits, diesel generator fuel lines, and marine bunker transfer all use turbine flowmeter hubs. A fuel depot in Indonesia needed pulse output for a truck loading skid. The line was DN25 and the flow range was 5 to 50 L/min. Our team supplied a 316 stainless steel turbine flowmeter with a spare hub. The site team calibrated the meter with a standard volume prover.
Turbine hubs are not ideal for heavy fuel oil or dirty fuel. If the fuel contains solids or wax, install a strainer. For heavy fuel oil above 50 cP, use a positive displacement flow meter. You can contact us for an oval gear flow meter recommendation.
Send us the fuel type, pipe size (DN), flow range in L/min or kg/h, pressure (bar), temperature (°C), and output signal. Also tell us if you need ATEX Zone 1 or Zone 2. Most fuel loading terminals use Ex d or Ex ia pickups. We can supply that.
What is a turbine flowmeter hub? It is the rotor module that spins inside the meter body and generates the flow signal.
Can I replace only the hub in a fuel line meter? Yes. If the meter body and pickup are good, a replacement hub is a low-cost option. Provide meter size, flow range, and serial number.
What fuel types work with turbine flowmeter hubs? Diesel, gasoline, jet fuel, kerosene, and light oil with viscosity from 0.5 cP to 5 cP. Avoid dirty fuel unless you add a strainer.
What output do these hubs provide? The sensor outputs a pulse frequency. You can convert to 4-20 mA or 4-20 mA HART through the transmitter.
