This non-reset tokico flow meter can't be reset or can't be calculated starting from 0 again. The calculation process is continuous from the beginning of use to the end of use. So what is visible on the counter is the accumulated value from the calculation of its use.
This flow meter is included in the positive displacement flowmeter.
Tokico's flow meter material is made of cast iron, that's why Tokico can't be used for liquid water because if it is used for water, this flow meter material will easily rust.

The positive displacement type flow meter can be used at relatively high rotational speeds, resulting in a compact design. In addition, this meter counter unit is compact yet easy to read, and its construction is simple.
