Rf Principle based Level Sensorshave been designed based on the considerations discussed and various other aspects. Flowtel’s Rf Level Sensors are highly reliable for use with materials that are conductive or nonconductive, granular or slurries, fines to large particles and contaminated or p u r e l i q u i d s a t v a r y i n g temperatures and pressures
Flowtel’s Rf Level Switch Series FLRF 20 Models work on Rf Principle. Independent but identical low power Rf signals equal in frequency, phase, amplitude and wave shape generated in the Electronic Controller are provided to active and shield sections of the Sensing Probe, whereas, the reference ground of electronics is connected to the vessel shell. The signal provided to the shield section is maintained constant by use of a compensating circuit in the Electronic Controller while the signal applied to the active section varies with change of media between probe and the vessel shell/wall.
The suspended dust or material in-transit do not have cohesive inter-particale contact, and have no role in this Rf Principle of Level Sensing. The variation in active signal is compared with the constant shield signal. At a predetermined value of difference a relay is actuated to obtain potential free relay change-over contacts for further alarm and controls.
TOP MOUNTED MAGNETIC LEVEL SWITCH
A magnetic float moves up and down on probe immersed in a liquid. The float energizes the hermitically sealed sensors, which
change from NO to NC or otherwise as the float – passes them.
- Versatile System Contact Points can be changed
in accordance with process necessity - Less Wear & Tear- Easy on Maintenance
- Inter linking liquid level in parallel tanks
- External cage on request
