(2) Obtain the maximum frequency for each size by calculation. Max. frequency (Hz) = Max. flow rate (cc/s) / K-factor (cc/pulse) (1) For wire extension, it is recommended to use shielded wires. (2) For display of flow rate, an indicator is required separately. (3) The cover attachment method varies depending on the materials. In the case of PP, the cover is tightened using hexagon socket head cap screws (inch screws). In the case of PTFE, it is sandwiched between hexagon socket head cap screws and inch screws. See A-1.
