On-line installation, mechanical flow switch, for liquid or gas medium. Sturdy plastic, aluminum or stainless steel case is optional. Minimal pressure loss, good repeatability, anti-fouling ability, complete isolation between mechanical and electronic parts, suitable for low flow economy. 3 times the piston stroke of the original RST-HS to make the setting accuracy more accurate. With a switch setting scale, users do not need to set in the field. LED display switch status, double switch output optional. Gas-liquid dual purpose, industrial automation/mechanical equipment/air compression industry/refrigeration and air conditioning.
