Abstract
A transducer control arrangement in a hydrostatic pipe testing machine or pipe tester, for preventing a change in the positioning of the pipe relative to a testhead seal as testing fluid is introduced into the pipe. A transducer signal activates at least one pump to operate a piston cylinder assembly connected to the testhead to reduce or eliminate any relative movement between the testhead seal and the pipe.
