INQUIRY

Application

CX-FS-FE20 type used for gas and liquid . Suitable for industrial automation / mechanical equipment/compressed air industry /refrigeration and air conditioning .

Feature

1,On-line installation 2,Mechanical type flow switch 3, Suitable for gas and liquid 4,Firm plastic, aluminum or stainless steel housing 5,Small pressure loss 6,Good repeatability and stain resistance 7,The mechanical part isolate from the electric part totally , it is economical type and suit for small flow range. 8, 3 times piston journey respond to original FE20 , which makes sure the high accuracy . 9, With switch setting scale ,so the used does not need to set in field . 10, LED display the switch state (option: double switch value output)

Note :

1, The parameter in bracket is reset point, the parameter outside the bracket is action point .If the lower limit alarm (the monitoring flow rate is too small) ,at the time reference the reset parameter . If the upper limit alarm (the monitoring flow rate is too big) , then reference the action parameter .

2, Under vertically installing on horizontal pipe , then test to get the above parameter for 20 Celsius degree water..

1. It should mention the medium direction , medium ,pipe diameter and the expected set value ,when placing the order . Then we can set it before leaving factory .

2,If the medium is viscous medium , please notice the viscosity , temperature and medium .

3. If the medium is gas , please notice the pressure( meter pressure /absolute pressure) ,temperature and medium .

Optional accessory
