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.
