pic-top-1

 

The system is designed to study the frictions of fluids used for well pumping and hydraulic fracturing. Process liquid is pumped through 2 lines of a various diameter; pressure variation for the selected discharge range is measured there. The unit operates over one cycle with recycling of the investigated liquid. Precise fluid discharge is measured with a mass-rate flowmeter.
