청구항

A method for measuring the change in the temperature-compensated flow rate produced by a leak while compensating for thermally induced volume changes in a pressurized pipeline system containing a liquid product, comprising: (a) pressurizing said pipeline system to a first pressure and measuring with measurement means those changes in the volume of product in said pipeline that are required to maintain approximately constant pressure over a first measurement period; (b) changing the pressure in said pipeline to a second pressure and measuring with said me...
