Abstract
Test apparatus for proving the performance of Coriolis mass flow meters when measuring high-temperature fluid. Selected heat transfer fluid, preferably organic, is heated to the desired testing temperature and pumped from a fluid reservoir and heater through the meter being tested. A batch tank receives the fluid passing the meter and the tank is weighed before and after the test to prove the meter. All conduits connecting to the batch tank are flexible and the weighing scales operate with a minimum of deflection. An inert gas blanket is maintained in the fluid reservoir and the batch tank to maintain the selected organic fluid in a liquid state. The components of the apparatus are mounted on a platform and the apparatus can be easily transported for testing meters in the field.
