Device for calibrating and/or monitoring certain operation condition of test mass flow measuring device, has tanks star-connected with each other, and tank device coupled to balancing device

摘要

The device (12) has a tank device (56) including tanks (20, 40), and a flow path (14) for fluid attached or connected to a test mass flow measuring device (10). One of the tanks is arranged in the flow path, and a reference mass flow measuring unit is attached to another flow path (16) for fluid. The tanks are star-connected with each other, and the tank device is coupled to a balancing device (64). The tank device and the balancing device are connected with each other, and the test mass flow measuring device is in flow connection with an input (26) of the tank. An independent claim is also included for a method for calibrating and/or monitoring a certain operation condition of a test mass flow measuring device.
