•Adjustable indicating air flow controller

•Suitable for level and air purge control

•Tamperproof cover

•High Accuracy

•Available in Standard and Hazardous applications

Industry:

Ideal for control room installation for level control applications.

Solution:

The FRI unit needs sufficient air pressure or gas pressure (nitrogen is used in some instances) at the inlet port to exceed the maximum expected head pressure plus 5 psi. This will ensure that a flow can be established, when levels are at their maximum.
