Shandong Heze circulating water tap water flowmeter
>Electromagnetic flowmeter product features
>
There are no moving parts in the pipeline, no flow-blocking parts, and there is almost no additional pressure loss during measurement.
>
The measurement results are related to physical parameters such as flow velocity distribution, fluid pressure, temperature, density, viscosity, etc.
>
The measuring range can be modified online on-site according to the actual needs of the user.
>
High definition backlight display, full Chinese menu operation, easy to use, simple to operate, easy to learn and understand.
>
Using

components and surface mount (

) technology, the circuit has high reliability.
>
Using a

embedded microprocessor, it has fast operation speed, high precision, and programmable frequency low-frequency rectangular wave excitation, which improves the stability of flow measurement and has low power consumption. .
>
Full digital processing, strong anti-interference ability, reliable measurement, high accuracy, and the flow measurement range can reach

:

. Ultra-low

switching power supply, suitable for a wide range of power supply voltage changes, and good resistance

performance.
>
There are three internal totalizers that can respectively display the positive cumulative amount and the difference cumulative amount. There is a non-power-down clock inside that can record the times

power time. (Optional)
