Electronic Liquid Level Controllers

Updated on June 8, 2013

Types of Electronic Liquid Level Controllers

Electronic liquid level controllers is the liquid sensors which are used for detecting the flow of level of liquids, granular materials, slurries and powders. Fluidized solids or fluids flow for becoming leveled in their physical boundaries or in their containers because of gravity and most of the solids which are in bulk pile to a peak of angle of repose.

The liquids or substances which are measured can be in its natural form like in a lake or river or can be in its container. The measurement of level can either be in point values or continuous.

The measurements by continuous level sensors are done within a specified range which helps in determining the exact quantity of the materials in a particular place. The point level sensors are used for indicating whether the material is below or above the sensing point and mainly these are used for detecting extreme low or high levels.

The level sensors which are used for measuring continuous level of liquids include the magnetostrictive level sensors, magnetoresistive float level sensors, resistive chain level sensors hydrostatic float level sensors, gamma ray gauge and air bubbler system.

The level sensors which are used for detecting the point level of liquids include the mechanical and magnetic float level sensors, conductive level sensors and pneumatic level sensors. The level sensors which are used for both continuous monitoring and point level detection of liquids include the capacitance level sensors, ultrasonic level sensors, microwave sensors and optical sensors.

The point level detection of liquids is perfectly done by the conductive level sensors. These sensors are used for an extensive range of liquids like water and are well suited with the liquids which are highly corrosive like hydrochloric acid, caustic soda, ferric chloride, nitric acid and other similar liquids. The electrodes of the sensors are fabricated from titanium, 316 stainless steel insulated with spacers, Hastelloy B or C, Teflon based or polyethylene materials and holders or separators of ceramic which are used with corrosive conductive liquids.

Multiple electrodes of varying length are used with one holder which depends upon the design of the sensors. When these sensors are specified the extreme conditions, pressure and temperature of corrosive liquids are considered because these conditions increase or become aggressive when these liquids react.

These level sensors use power with current limit and low voltage which are functional across separate electrodes. The power supply is coordinated according to the conductivity of liquids like for less conductive mediums higher voltage versions are fabricated for operations. Some feature of control is incorporated by the power source frequently like alternating or high low pump control.

A conductive circuit is completed by the shorter probe for return and longest probe for common in contacting the conductive liquid. These sensors are extremely safe as these use currents and low voltages. The technique used in these sensors is intrinsically safe because the voltage or current used is inherently small.

The capacitance level sensors are used for the dielectric constants because these use higher frequencies and phase modulation. These sensors eliminate or reduce the problems caused by corrosion and abrasion. All types of Electronic liquid level controllers are available online. Persons or organizations interested in availing these controllers can directly contact the manufacturers in their official websites.
