| Zusammenfassung: | The utility model discloses a liquid flow tester which comprises a differential pressure transmitter (1), a single chip computer unit (2), a keyboard (3) and a display unit (4). On the basis that the corresponding relationship exists between the differential pressure and the lift, and between the lift and the of the lift of both ends of a liquid pump, the liquid flow is measured by measuring the pressure difference of both of the two ends of the liquid pump. Compared with the prior art, the pipeline installing place of the utility model is the installing place of the liquid pump; therefore, the utility model has the advantages of accurate measurement, no flow rate requirement, no straight-pipe section requirement and convenient installation. The utility model can be used for measuring and metering various occasions that are dissatisfied with the straight-pipe section requirement and the flow rate requirement. |
