CFS meaning in oil and gas

The spinner is mounted on precision roller bearings and turns as fluid moves passed it, this rotation is converted to signal pulses by zero drag Hall-effect sensors. The pulses are then used to calculate flow rates and fluid direction (up or down flow); the flowmeter requires very little energy to initiate motion and is ideal for low flow rate surveys. The design and mechanical construction of the spinner assembly have been optimized to cope with very fast flow, sand production and high viscosity liquids. Each model has a different size housing and impeller, and should be chosen to suit the well completion and flow regime.
