ABSTRACT:
A tensiometer apparatus for use in the field, for instance at the site of an oil well, for measuring the interfacial tension between two immiscible fluids, for instance oil and water, wherein a droplet of one fluid is caused to move under the force of gravity through the second fluid and a characteristic of the droplet is determined by measuring the change the droplet causes in capacitance of one or more capacitors as the droplet moves through the second fluid. The determined characteristic is then converted by calibration means to interfacial tension between the fluids.
