Capillary Viscomete LECVM

The LECVM high-pressure capillary viscometer accurately determines the viscosity of single phase reservoir fluids. The apparatus is based on Poiseuille’s law; specifically the relationship between pressure drop, flow rate, fluid viscosity and pipe geometry for a Newtonian fluid flowing in the laminar regime (Re<2300) through a constant cross-section pipe. By measuring the pressure drop and flow rate, fluid viscosity can be deduced.

The computer-controlled instrument consists of a high-pressure opposed pump, two highly accurate pressure transducers, an isothermal convection air bath and a capillary tube. Moreover, to augment the range of measurable viscosities, a set of four different diameter capillary tubes are supplied.
