Variable Area Flow Meters Variable area flow meters are used to measure the volume flows of liquid and gases. Application of Variable Area Flow Meter – Volume flow measurements of Liquids and Gases Components – Vertical Conical Measuring Tube Mobile Float It…
The most common DC motors types are 1.The basic brushed DC motors 2.Brushless motor 3.Permanent Magnet motor Brushed DC motor In a brushed DC motor, the magnet acts as the stator.The armature is integrated onto the rotor and a commutator switches the…
Ultrasonic Level Detectors Ultrasonic sound waves with frequencies of 1 to 5 megahertz can be used to detect liquid or solid levels. Ultrasonic are sound waves but are at higher frequencies that cannot be detected by the human ear. The most common kind…
Manometers Manometers are one of the oldest type of pressure measurement. Manometers can be used to measure gauge pressure,differential pressure and absolute pressure. Various types of Manometers 1.U tube Manometer 2.Well type or reservoir manometer 3.Inclined manometer 4.Float type manometer U tube Manometer….
Magnetic GaugesMagnetic gauges can often be used in applications where a sight glass is not practical.A Magnetic gauge uses the attraction between two magnets to follow the level of a liquid.One magnet float on the surface of the liquid.The other magnet is…
Pressure measurement Pressure is an important process variable. Pressure is defined as force per unit area. Pressure = Force / Area Force can be represented as Pound force,Kilogram force,Newton,dyne Area can be represented as Square inches,Square feet,Suare Centimeter, Square Meters Common units…
Pressure regulatorSelf-Operated devices which work off the medium alonePressure reducing valve – PRV : Lowers inlet pressure to desired point How PRV works? Internal architecture of a Pressure regulator Basic Characteristics of a pressure regulator is standalone self actuating controllers. What to…
Valves are used for 1.Full flow of throttle :which is a wide range for valves use,because valves are designed in a way way to reduce pressure losses for fluids passing through theses valves,diaphragm valve is used with dangerous and toxic liquids. 2,Flow…
In a float operated level switch the float rides in the process liquid surface precisely tracking liquid surface motion.Rising liquid level lift the float sliding the attraction slip up inside the enclosing to and into the magnetic field to actuate electrical or…
The differences between circuit breakers and fuses. Both residential and industrial electronics circuits systems require some form of protection to prevent catastrophic failure circuit damage or loss of life due to excessive current brought on by a short circuit overload device failure or…
