The concept of utilizing electrical conductivity of most Liquids as a means of achieving float less level control Has won widespread acceptance as the most Reliable/versatile system of its kind.
This has been Successfully applied throughout the fertilizer, thermal Power station, refinery, steel, cement, sugar, chemical processing industries, in municipal water works and Sewage disposal plants and other industrial applications, where close, constant control liquids and moist bulk Materials is an important critical factor.
The principle of detection involved is the capacitance phenomena which is developed between the probe and the reference. The amount of capacitance developed in any vessel is determined by the size (surface area) of the probe, the distance from the probe to its ground reference, and the dielectric constant of the medium being measured.
The amount of capacitance developed in a vessel becomes dependent upon the amount of the probe which is covered with media. As the media rises and falls in the tank, the amount of capacitance developed between the probe and the ground reference also rises and falls.
This change in capacitance is detected by employing radio frequency (RF) and converted to a digital waveform proportional to the change in level which in turn is used for level Detection and monitoring.
It uses proven RF technology to solve all process level measurement and control problem. Whatever may be your application or control requirement we have the widest range to cater to all your needs.

Buoyant force of the liquid on the float is used for movement of the permanent magnet closer to or further away from reed switch and initiates the switching function of high and low level.
The unique feature of reed switch technique is adopted. Product technique, concept, merit, quality and unparallel Reliability are the underlying reasons for enviable Performance record. Level switches with micro switch And air break type switch is also available.
All control have been designed using modular concept. standard assemblies may be incorporated in a Wide variety of arrangements to meet virtually any control application n allowing maximum Interchangeability of assemblies it’s unique engineering & manufacturing capability handles Your special process requirements promptly with out Long delays at an economical cost. The basic operation principle for magnetic switch action results from A change in liquid level, which moves a magnetic attraction sleeve (ss410ims) into the field of an externally located ‘u’ magnet.

It’s magnet operated float switch is equipped with Glass encapsulated reed switch. Float embedded With magnet moves up & down around the guide Tube according to the level. reed switches are Actuated by the magnetic field of an annular magnet.
Balloon type float switch has a body exterior made of a durable and oil/acid resisting Synthetic compound. The device has been found extremely useful and dependable as a means for governing pumps and for signaling purposes. A weight body attached to the cable effectively prevents the cable from being sharply flexed.
The switching elements to Which the cable conductors are connected consist of a sealed mercury switch. It was developed and is being manufactured.
It is a simple and economical instrument suitable for the minimum and maximum level control inside silos or hoppers that contain non sticky materials, powders or granules like rice, corns, plastics, coffee, sand, lime, etc .
A membrane level sensor provides level indication by detecting pressure applied by the bulk material to the sensing Membrane. The unit is installed to a vessel wall so that the membrane is exposed to the material to be sensed.
As Material contacts the membrane, a force is exerted through the diaphragm to a pressure plate within the level sensor. Physical deflection of the pressure plate actuates an internal micro switch for signaling alarms, lights or plc inputs.
When material recedes from the membrane, a light duty spring returns the pressure plate and internal switch back to their Original positions. Humidity and temperature variations do not affect working; the membrane is collision and vibration proof.
The operation of paddle type hopper level control products is simple. The unit is installed through the wall of the vessel, so that the paddle protrudes inside the vessel.
A small electric motor drives a paddle which rotates freely in the absence of material. When the paddle is impeded by material, the motor rotates within the housing which triggers two switches. The first switch is a “dry” electrical contact closure that is available to control a process function or alarm circuit.
The second switch cuts the power to the motor, preventing a locked rotor condition, thus extending the motor life. This also activates the signaling device which is wired through that same motor switch. When the material level drops, the loaded stretched tension spring returns the motor to its original running position and the unit is activated.
The vibratory / tuning fork level sensor provides reliable point level detection in a wide variety of process control applications in bins, silos and hoppers, filled with grained or powdered materials or for liquids in a tank.
The vibrating probe principle eliminates problems associated with temperature, humidity and material changes, while providing state-of-the-art electronic reliability and accuracy That requires no calibration.
Tubular Level gauge is the simplest form of level indication in process industry It is simple and reliable device for direct reading in atmospheric or pressurized tank applications. It is mounted parallel, along the side of tank.As the process level fluctuates, the level in the transparent glass tube changes accordingly and gives local liquid indication.
Magnet embedded inside the float will move up and down according to the liquid level in the main vessel. A light weight magnetic follower inside the glass tube with adjacent plastic scale coupled to the chamber indicates float position and therefore tank level
This instrument consists of a metal body, machined to have an internal chamber and one or more front windows (on one side only of the gauge). On each window a special high resistance plate reflex glass is fitted with sealing joint and metal cover plates hold by bolts and nuts.
Transparent Liquid Level Gauge consists of a metal body, machined to have an internal chamber and one or more front windows (on each side of the gauge). On each window a special high resistance plate transparent glass is applied with sealing joint and metal cover plate hold by bolts and nuts.
Flow switch is the target type unit that works on the Magnetic principle of attraction. As the flow causes the flapper to deflect the magnet moves closer to or Further away from the switch causing the reed switch to actuate. Switching action is determined by flow & not by pressure. The unique features of reed switch Technique is adopted unique design, magnetic switching and uncompromised quality have resulted unparallel reliability.
Thermal dispersion flow switch monitors are compact Switches, with no moving parts, that can monitor and control The flow of liquid, air, and gas in pipes and ducts. They can also be used for single point level control of liquid or for interface Detection between mediums. Sitron’s series of flow switches Are available in five different models that provide for different Power supply, output, environmental and connection requirements.
