Magnetic Flowmeters for Measuring the Frac Fluid


A piece of equipment used in hydraulic fracturing is the blender truck. It contains the equipment used to prepare and measure the "frac fluid". Frac fluid is composed of water, sand, specialty chemicals, and gels, and is highly erosive and sometimes corrosive. This "blended" mixture of sand, water and chemicals is then injected into a well to hydraulically open cracks in the rock layers below. By opening the cracks, trapped natural gas and petroleum is released and flows more freely. 

Magnetic flowmeters are employed to measure the frac fluid flow and volume.  These flowmeters must accurately meter the frac fluid into the well, stand up to the continual erosive media, and be durable enough to handle the harsh ambient conditions. Standard process magmeters experience shortened lifespans under these conditions and must be pulled from service and repaired. A better alternative is a severe service flowmeters designed specifically for this service.

Thompson Equipment Company (TECO) manufactures an electromagnetic flowmeter (magmeter) designed for frac fluid flow metering. The TECO design incorporates two significant features to improve performance and extend operating life:
  1. A ceramic sleeved liner made of “magnesia partially stabilized zirconia”
  2. The use of solid tungsten electrodes.
The TECO fracing flowmeter provides huge benefits, namely operators save money through increased uptime, they reduce health, safety and environmental risk, and reduce costs related to magmeter replacement and repair.

The Operating Principles of a Magnetic Flowmeter

Below is a video, courtesy of Badger Meter, illustrating the operating principles of magnetic flowmeters (also known as magmeters).

A magnetic field is applied to the flow tube, resulting in an EMF proportional to the flow velocity passing perpendicular to the magnetic flux lines. The physical principle at work is Faraday's law of electromagnetic induction.

Magnetic flow meter requires a conductive fluid, and electrically insulated internal pipe surfaces to operate.

Advantages:
  • Low maintenance cost
  • No moving parts
  • Good for slurry
  • Good for corrosive fluids
  • Very linear
  • Minimal flow restriction

Disadvantages:
  • Requires electrically conductive fluids

The Magmeter Zone - Don't Let Your Flow Meters Die Here

Don't let this happen to your old flowmeters! 

Here's a video parody of the popular TV show "The Twilight Zone", only here it's the "Magmeter Zone", where old, worn out magmeters go to die. From the creative minds at TECO ... humor in magnetic flowmeters - who woulda thunk it?  Enjoy!
