Counters are used for measuring the ‘volumetric flow’ of the fluid in a pipeline.

There are many methods to measure Flow:

Of course we have to use Totaliser in order to counte nember of Puls if we need.

1. PD meter ( Turbine ), of course you have to use Totaliser to counte nember of Puls.
2. Coriolise ( Micro motion Emerson for exemple)
3. Ultra Sonic ( Flowsic 600 and 100)
4. Orifice Plate ( defferencielle Presure)
5. Venturi … etc
