The KLC is a device which uses plant air to function as a bubbler sensor
and controller within a single enclosure. It does not need another converter
and provides direct-acting, modulating pressure to the system’s
proportional control valve.
Its single module design and air conversion process is simple and there
are specific advantages over direct contact pressure transducers, ultrasonics,
lasers, probes, ball floats, or load cells. Some of which are:
- It needs no electrical connections nor external sensors.
- There are no moving parts.
- The sensing tube is not vulnerable to fouling like typical ball floats
or probes.
- The tube just needs a small opening, therefore it can fit almost
anywhere.
- There is no need for clearance to accommodate linkage movement as
required by ball floats.
- The output is a direct acting pressure at either, 0 to 35 psi or
0 to 100 psi.
- It can serve almost any diaphragm or cylinder actuator.
Its main application is to monitor liquid levels in reservoirs where
fluids are continuously flowing in and out to satisfy a process.
