The device has a base body (10), in which a main flow channel (12) is formed with a medium input (14) and medium output (16). A unit is provided in the main flow channel for producing pressure drop between two channels (18, 20) that are deviated from the main flow channel. The channels are guided to chambers (22, 24), in which absolute pressure measuring cells (26, 28) are arranged such that difference between measured absolute pressures is formed. A sealing element (49) is provided for sealing an insert (32) in the base body. An independent claim is also included for a method for adjusting maximum pressure difference in a flow rate measuring-or regulating device. |
