heavy fuel oil flow meter 1/2 inch
**Heavy Fuel Oil Flow Meter 1/2 Inch**
**Quick Answer:** For metering heavy fuel oil (HFO) at a 1/2 inch (DN15) line size, oval gear flow meters and Coriolis mass flow meters are the most reliable options. Oval gear meters handle high viscosity (up to 100,000 cP) and are cost-effective for custody transfer. Coriolis meters provide mass flow, density, and temperature in one device, best for applications needing precise batching or blending.

### 二、Why 1/2 Inch Size Matters for HFO
Heavy fuel oil has high viscosity. At room temperature, HFO can be thicker than peanut butter. Most flow meters designed for water or light oils fail with HFO because the fluid sticks to internal parts or the pressure drop is too high.
The 1/2 inch pipe size is common in small burners, auxiliary engine fuel lines, and test benches. For example, a marine generator on a 10,000 DWT vessel migh
t have a 1/2 inch HFO supply line. A chemical plant in Indonesia might use a 1/2 inch line for a small reactor heating system.
When you meter HFO in a small line, you need a positive displacement meter or a Coriolis meter. Other technologies like electromagnetic or vortex meters cannot handle the high viscosity or do not work with non-conductive fluids.
### 三、Best Flow Meter Types for 1/2 Inch HFO
**1. Oval Gear Flow Meters**
Oval gear meters are the industry standard for HFO. They work by trapping a fixed volume of fluid between two rotating gears. The rotation speed is proportional to the flow rate.
Key specifications for a 1/2 inch oval gear meter:
- Pipe size: DN15 (1/2 inch BSP or NPT threads)
- Viscosity range: up to 100,000 cP
- Flow range: 0.1 to 20 L/min
- Accuracy: ±0.5% of reading (with calibration)
- Temperature: up to 150°C for standard models, 200°C for high-temp versions
- Output: 4-20 mA HART, pulse, or Modbus
For HFO, you need a meter with PTFE or FKM seals. Carbon steel body with hardened gears works best. If the HFO contains abrasive particles, add a Y-strainer upstream.
Last year, a customer in Vietnam asked us for a 1/2 inch HFO flow meter for a small asphalt heating plant. They needed ±1% accuracy for inventory tracking. We supplied an oval gear meter with pulse output and a local display. It runs 24/7 and has worked for 14 months without issues.
**2. Coriolis Mass Flow Meters**
Coriolis meters measure mass flow directly. They do not need viscosity compensation. They give mass flow, density, and temperature in one device.
Key specifications:
- Pipe size: DN15 (1/2 inch)
- Flow range: 0.5 to 50 kg/h (for the smallest model)
- Accuracy: ±0.1% of reading
- Temperature: up to 350°C for some mo『SILVER Official Website SERVICE』
