Introduction

Float operated liquid level transmitter, indicator and controller, comprises of a level transducer and a signal converter and is used for continuous level indication and control of any liquid, chemically compatible with the transducer material, unaffected by electrical conductivity, temperature, pressure or viscosity.

Operating Principle
The Unit operates on the principle of buoyancy. During the rise and fall of liquid level, the Float moves and the magnetic field changes & actuates the chain which develops a proportional voltage. The sensed voltage is fed to a transmitter for converting it to a signal of 0-5 V Dc or 4 â 20 mA. The transmitter can also be incorporated with a digital display or step less adjustable multiple alarm relays (featuring high level alarm, low level alarm, or both & low level pump (or solenoid valve) on & high level off and vice-versa.

Construction
The transducers consist of a float and guide tube assembly in non-magnetic material to achieve undisturbed flux. The float can be in nylon, PP or SS. No gasket or seals are used and there is only one moving part, the float assuring long trouble free life. Being entirely glandless, there is no possibility of fluid leakage into the transducer.

Installation and Wiring
The transducer is mounted internally and externally through a chamber by means of a flange connection. External mounting is adopted to overcome limited space within the tank or where mechanical devices operate or where isolation tank is required for regular servicing. The Transducer is precalibrated in the factory and comes to you ready for installation. For operation of level transducer, it has to work in conjunction, with a signal converter which have line or loop powered electronics. Line powered transmitter can be incorporated with a digital display and / or adjustable multiple alarm relays. Loop powered transmitter is employed for remote signaling to a process indicator / controller.
