Principle and Structure: Online installation, mechanical flow switch, Be used in liquid or gas media. Solid plastic, aluminum or stainless steel housing are optional.
Main Feature: Very few pressure loss, satisfactory repeatability and anti-pollution, mechanical and electronic parts are isolated completely. More accurate setting accuracy, with setting dial gauge, easy setting, user no need to set on site, switch status displays in LED.
Application: Can be used in both gas and liquid, industrial automation, mechanical equipment, air compressor industrial, HVAC.

Remark:
1. Data in above parentheses is reset point while the other is operating point, Please refer to reset point data while in lower limit alarm(monitoring too small fow), and refer to operating point data while in upper limit alarm(monitoring too large flow).
2. Above data is based on the test that switch is installed on horizontal pipe vertically and use 20℃ water as media.
3. Above proof pressure data is based on 304 stainless steel materials, proof pressure 50bar, 20bar are optional either.
