We are Importer of All Flow Meters Types in PakistanTurbine meters, Magnetic flow meter, Positive displacement, Ultrasonic flow meters,

1. Positive Displacement (PD) Flow Meters

  • Description: These flow meters measure the volume of fluid passing through the meter by trapping a fixed volume and counting the number of times the volume is displaced. They provide high accuracy, especially at low flow rates.
  • Applications: Ideal for measuring viscous fluids, such as oils, syrups, or fuels.
  • Types: Gear meters, piston meters, diaphragm meters, and nutating disc meters.

2. Electromagnetic (Mag) Flow Meters

  • Description: Mag meters measure the flow of conductive liquids based on Faraday’s Law of electromagnetic induction. The fluid must have a certain level of conductivity for this meter to work.
  • Applications: Used for measuring water, wastewater, chemicals, and slurries.
  • Advantages: No moving parts, very accurate, and capable of handling a wide range of flow rates and pressures.
  • Limitations: Cannot measure non-conductive liquids.

3. Turbine Flow Meters

  • Description: These meters use a rotor (turbine) that spins as the fluid flows through the meter. The rotational speed of the turbine is proportional to the flow rate.
  • Applications: Common in industries where low to medium flow rates of liquids or gases need to be measured.
  • Advantages: High accuracy and good performance in clean, steady flow conditions.
  • Limitations: Sensitive to changes in flow characteristics, such as turbulence, and requires regular maintenance due to moving parts.

4. Vortex Flow Meters

  • Description: Vortex meters work by detecting the vortices (swirling patterns) created when the fluid flows past a bluff body in the flow stream. The frequency of the vortices is proportional to the flow rate.
  • Applications: Suitable for measuring steam, gases, and liquids, including chemicals and water.
  • Advantages: No moving parts, high accuracy, and a wide range of applications.
  • Limitations: Can be affected by pipe geometry and flow conditions like turbulence.

5. Ultrasonic Flow Meters

  • Description: Ultrasonic meters use sound waves to measure the flow of fluids. There are two primary types:
    • Transit-time: Measures the time difference of ultrasonic pulses traveling upstream and downstream.
    • Doppler: Measures the frequency shift in sound waves caused by suspended particles in the fluid.
  • Applications: Commonly used for water, oil, natural gas, and other clean liquids.
  • Advantages: Non-invasive (for clamp-on types), high accuracy, and no pressure drop.
  • Limitations: Requires clear or clean fluid for accuracy, and installation can be expensive.

6. Coriolis Flow Meters

  • Description: These meters measure mass flow and density of fluids by detecting changes in the vibration of a tube through which the fluid flows. The Coriolis effect causes the tube to bend as fluid flows through it, and this deformation is directly proportional to the mass flow rate.
  • Applications: Ideal for measuring precise mass flow in high-accuracy applications such as chemicals, pharmaceuticals, and food and beverage.
  • Advantages: Very accurate for mass flow and density measurement, works with almost any fluid, including gases and slurries.
  • Limitations: Expensive and sensitive to vibrations and temperature changes.
