Yes, the water mark calibration device is a type of flow meter calibration device.
The calibration device of a water meter generally has a photoelectric transmitting device that converts the rotation of the impeller of the mechanical water meter into an electrical signal for the computer to count and detect the accuracy.
The flow meter calibration device not only detects pulse signals, but some also need to receive current signals, voltage signals, etc.
Your industrial computer must support the collection of this signal.
In addition: Some flowmeters need to verify instantaneous flow, such as differential pressure flowmeters and float flowmeters. This requires the instantaneous flow of the device to be very stable. This is related to the voltage stabilization method and calibration method. , is it the static volume method? Dynamic volumetric method? Static weighing method? It is related to the dynamic weighing method or the standard table method and other calibration methods.
Generally speaking, ordinary water meter calibration devices include a certain calibration method, but they are not necessarily suitable for the calibration of all flow meters.
Furthermore, the flow rate of conventional water meter calibration devices is very small, and it is only suitable for calibrating flow meters with small diameters. For example, turbine flow meters within DN25 can be calibrated without many modifications.
