Oval Gear Flow Meter

An oval gear flow meter provides high measurement accuracy and is ideal for high-viscosity liquids. However, it is unsuitable for fluids containing solid particles, which may jam the gears, or for liquids with entrained gas, which can cause measurement errors.

The oval gear flow meter can be customized according to your requirements. Different liquid (acid, alkali, salt, oil, organic solution, etc.) flow meter bodies can be made of different materials. By equipping the flow meter with a signaling device and electronic display, it can achieve centralized remote control of cumulative, quantitative, and instantaneous flow. A liquid crystal digital counter enables on-site display of real-time and total flow, while supporting remote transmission through pulse, current, or communication signals. With a radiator or gear teeth design, it can also handle high-temperature and highly viscous liquids. Thermal insulation jackets can be installed to conduct heat tracing and insulation of the flow meter.

 

Flow measurement has nothing to do with the flow state of the fluid, because the oval gear flow meter relies on the pressure head of the medium to be measured to push the oval gear to rotate. The higher the viscosity of the medium, the smaller the leakage amount that leaks out from the gear and the measuring space gap. Therefore, the greater the stickiness of the medium under test, the smaller the leakage error, and the more favorable it is to the measurement.

 

 

An oval gear flow meter is a type of positive displacement flow meter. It is used for precise continuous or intermittent measurement of the flow or instantaneous flow of liquid in pipelines. It is especially suitable for flow measurement of high viscosity media such as heavy oil, polyvinyl alcohol, and resins.

  • Conventional accuracy ±0.5%, high-precision model can reach ±0.2%;
  • Good repeatability, 0.5 level accuracy repeatability <0.17%, 0.2 level accuracy repeatability <0.07%;
  • Mechanical structure performance is more stable, viscosity adaptability is stronger, and temperature resistance is higher.
  • The range is large, and the starting flow is small. Normal measurement can be achieved even below the lower limit of flow.
  • Strong viscosity adaptability, the viscosity measurement range can reach 0.3~2000 mPa.s;
  • Easy to install, no need to install straight pipe sections in front of the meter.
  • Wide temperature resistance range, temperature adaptation range can reach-40~+300℃.
