FLOW 45

Battery powered flow meter

It was especially designed for placing it in the areas without any supply voltage and its ideal placement is on main pipelines, sewerage or various sewage conduits. The flow meter excels in high accuracy within the entire flow range.

Prior to every measurement, automatic diagnosis of all functions and components that are necessary for proper admeasurement takes place. Based on the results, the meter is able to identify if the pipeline is empty and it cancels the entire measurement and/or conversely, it will evaluate the flow direction and include the results in corresponding summation registries.

Battery charging is directly dependent on the measurement period selected and on the outputs used; in case of a 10-sec period, the service life is 6 years min.

ELECTRONICS

The evaluation unit setting can be carried out in three ways; namely by using internal buttons, via PC or NTB using the Micro USB connector, and/or by programming the loader on the micro SD card (resetting is carried out by its loading).

For calculation of battery service life, besides the period of measurement, outputs or communication used are important as well. The more power demanding outputs are, the shorter battery service life is. That is why it is necessary to select very carefully the type of communication or outputs as well as data transmission period.
