AFM series is a rotating piston flowmeter. Due to their characteristics, they can be used in all those industrial applications where liquid measurement with low to medium viscosity is required. Its simple design (only one moving part) ensures a long service life and very low operating costs. Components of the ACM that come in contact with the medium are either made of AISI 316 stainless steel (upon request) or PVC (depending on the process fluid).
ACM series flowmeters have the following components:
- Measuring chamber containing a rotating piston;
- Waterproof o-rings made from Viton® or PTFE;
- Ryton® piston (or PVDF) with two permanent magnets;
- The switch is of REED type, it is mounted in a suitable housing and located outside the sensor.
