Product details
principle structure
Online installation, mechanical flow switch, used for liquid or gas media. Durable plastic, aluminum or stainless steel casing is optional. The medium can push the plunger spring to the set position, and then apply a magnetic field to the reed switch to output a passive on-off signal and provide instantaneous flow trend indication.
characteristic
The sensor components are fixed with double bolts, making the switch applicable to high-frequency vibration working environments.
application
Gas liquid dual-use type, industrial automation/mechanical equipment/air compression industry/refrigeration and air conditioning

Note: 1. (*) Parameters in parentheses are reset points, while parameters outside parentheses are action points. If the lower limit alarm (monitoring flow rate is too low), refer to the reset point parameters. Upper limit alarm (monitoring excessive traffic)
Reference action point parameters.
The above parameters were obtained by installing the switch in a horizontal pipeline and testing it with 20 ℃ water as the medium.
