Reed Chain Level Transmitters – FLX

Description

It consists of a float & guide stem assembly in non-magnetic material to achieve undisturbed flux. A chain of closely spaced glass encapsulated reed switches & resistors is placed inside the guide tube. During rise and fall of liquid level, the float moves & actuates a series of reed switches in the chain, through a magnet system within it and develops a proportional resistance. The operation is similar to a sliding resistance potentiometer. The sensed resistance is fed to the transmitter located in the enclosure for conversion to a signal of 4-20 mA.

Wherever it is not possible or desirable to install Float Level Transmitter directly onto the vessel, switches can be installed in an External Chamber. This arrangement gives smooth level control irrespective of turbulence in the process vessel and prevents accidental damages to the switch during shutdown or maintenance of the vessel. Chambers are used in applications which require isolations of process, High Pressure /High-Temperature applications, Corrosive applications, Onshore / Offshore installations.

The main function of these chambers are :
1. Level Measurement
2. Interface Measurement between two liquids.

FEATURES :
• Available for Low Pressure and High-Pressure applications.
• Wide range of material of construction to suit different environmental conditions.
• Wide range of end connection types/sizes to choose from.
• A variety of chamber mounting arrangements provided to suit existing nozzles.
