Nutating Disc Flow Meters Working Principle

S Bharadwaj Reddy
Nutating disc meters are one of the most common types of positive displacement flow meter. They operate by having a disc mounted to a central ball. When fluid enters the

Oscillating Piston Flow Meters Working Principle

S Bharadwaj Reddy
Oscillating piston meters use a precision-machined chamber containing a cylindrical piston that oscillates as liquid flows. The piston’s central shaft is constrained to run in a circular groove in the

Swirl Flow Meters Working Principle

S Bharadwaj Reddy
Swirl flowmeters combine the advantages of turbine and vortex flowmeter technologies. They have a high turndown ratio and high accuracy (turbine). And they are highly reliable, robust and maintenance free (vortex) Swirl Flowmeters

Vibrating Tube Densitometers Working Principle

S Bharadwaj Reddy
One of the many parameters that must be accurately measured for product quality control, custody transfer, process control, or liquid interface detection purposes is liquid density. Often density measurement is

Pitot Tube Working Principle

S Bharadwaj Reddy
The Pitot tube is named after Henri Pitot who used a bent glass tube to measure velocities in a river in France in the 1700s. Pitot tubes can be very

Proximity switches Circuit Diagram Operation

S Bharadwaj Reddy
A proximity switch is one detecting the proximity (closeness) of some object. By definition, these switches are non-contact sensors, using magnetic, electric, or optical means to sense the proximity of objects. A

Pushbutton switches and Types of Switches

S Bharadwaj Reddy
A hand switch / Pushbutton switch is exactly what the name implies: an electrical switch actuated by a person’s hand motion. These may take the form of toggle, pushbutton, rotary, pull-chain,

Basics of Switches – NO/NC Contact

S Bharadwaj Reddy
Perhaps the most confusing aspect of discrete sensors is the definition of a sensor’s normal status. Electrical switch contacts are typically classified as either normally-open or normally-closed, referring to the open or

Deluge Valve Working Principle

S Bharadwaj Reddy
What is a Deluge Valve ? Deluge Valves are used in conditions that require for quick application of large volumes of water and, for that reason, are often integral components in

Circuit Breaker Working Principle Animation

S Bharadwaj Reddy
A circuit breaker is an automatically-operated electrical switch designed to protect an electrical circuit from damage caused by overload of electricity or short circuit. A circuit breakers function is to
