Flowmeter
In a flowmeter having a displacement meter (1), a pressure different sensor (3) connected in parallel has a bypass channel (8) which, when the piston (7) is at the maximum travel stop (9) thereof, enables a connection between the inflow and outflow sides (4, 5). A check valve (11) which prevents the...

| Zusammenfassung: | In a flowmeter having a displacement meter (1), a pressure different sensor (3) connected in parallel has a bypass channel (8) which, when the piston (7) is at the maximum travel stop (9) thereof, enables a connection between the inflow and outflow sides (4, 5). A check valve (11) which prevents the return flow from the outflow side to the inflow side (5, 4) and therefore enables a purely pressure-induced return of the piston (7) is arranged in the bypass channel (8). |
