What are Strain Gauges? How Strain Gauge Works?
What are Strain Gauges? It is often easy to measure the parameters like length, displacement, weight etc that can be felt easily by some senses. However, it is very difficult to measure the dimensions like force, stress and strain that cannot be really sensed directly by any instrument.
What is a Bourdon tube? Flow Control Network
The Bourdon pressure gauge operates on the principle that, when pressurized, a flattened tube tends to straighten or regain its circular form in cross section. The Bourdon tube comes in C, helical, and spiral shapes—although most gauges employ the C
Radar Tank Gauge for Oil, Product and Chemical tankers
Radar Tank Gauge GLA 300/P for oil, product and chemical tankers. The KONGSBERG Radar Tank Gauge, GLA 300/P, is designed with an offset parabolic antenna where both the signal transmitter and the parabolic antenna is angled 45 degrees to allow for natural draining should condensation and deposits from the tank atmosphere occur.
Principle of Operation for Servo Tank Gauge JOYO M&C
Principle of Operation for Servo Tank Gauge. Our servo tank gauge operates on the principle of displacement measurement. A small displacer on a measuring wire is unwound from a drum and accurately positioned in the liquid medium using a servo motor.
Oil tank gauge, how much oil is in the oil tank?
Oil tank gauges: How to find, read & test the oil tank gauge how much oil is in the heating oil storage tank? Types of oil tank gauges to measure how much oil is in the oil tank; Special gauges for buried oil tanks underground tanks tell how much oil is in the tank without having to use a dipstick; Heating oil tank gauge accuracy, inspection, installation, defects, repair guide; How do
What is a Thermocouple & How Does it Work? Principle of
A thermocouple is the devise used extensively for measurement of the temperature of the body. It is composed of at least two metals joint together to form two junctions. One is connected to a body of known temperature, while the other is connected to a body of unknown temperature. This enables us to measure the temperature of the unknown body by comparing it to the known.
The Sending Unit How Fuel Gauges Work HowStuffWorks
In the sending unit, the fuel has to drop below a certain level before the float starts to drop. When the float is near the top of the tank, the wiper on the variable resistor rests close to the grounded (negative) side, which means that the resistance is small and a relatively large amount of current passes through the sending unit back to the fuel gauge.
Level sensor Wikipedia
The principle behind magnetic, mechanical, cable, and other float level sensors often involves the opening or closing of a mechanical switch, either through direct contact with the switch, or magnetic operation of a reed. In other instances, such as magnetostrictive sensors, continuous monitoring is possible using a float principle.
MOG in Transformer (Magnetic Oil Level Gauge) Electrical4U
Again when oil volume is reduced due to fall in oil temperature, the oil level in the conservator goes down. But it is essential to maintain a minimum oil level in the conservator tank of transformer even at lowest possible temperature.. All large electrical power transformers are therefore provided with a magnetic oil level indicator or magnetic oil gauge.

Auto tank gauges, for atmospheric or for tanks with low pressure and non toxic fluids; Servo operated displacer type transmitter for pressurized tanks, bullets and for Tank Gauging requiring high accuracy.
Bourdon's Tube Pressure Gauge: Principle, Diagram
Bourdon's Tube Pressure Gauge: Principle, Diagram, Explanation Basic Principle of Bourdon tube pressure gauge: when an elastic transducer ( bourdon tube in this case ) is subjected to a pressure, it defects. This deflection is proportional to the applied pressure when calibrated. Operation
Float Type Level Indicator Principle Instrumentation Tools
Tanks controlled using tape level gauges will often overflow when the tape is stuck. This problem can be protected against by the use of a separate high level switch. More advanced controllers are available that monitor tank capacity and pumping rates to check the actual level, rate of change and direction of change. Summary
Bourdon tube Pressure Gauge Instrumentation and Control
As the pressure in the case containing the bourdon tube is usually atmospheric, the pointer indicates gauge pressure. Applications of Bourdon Tube pressure gauge: They are used to measure medium to very high pressures. Advantages of Bourdon tube pressure gauge: These Bourdon tube pressure gauges
Level Measurement Transparent Level Gauge, Reflex Level
Operating principle The operation of the magnetic level gauge is based on some elementary physical principles: The principle whereby the liquid in communicating vessels is always at the same level; Archimede's principle according to which a body immersed in a liquid receives a buoyancy equal to the weight of displaced liquid
Bourdon tube pressure gauge operating principle WIKA blog
Bourdon tube pressure gauges are the most frequently used mechanical pressure measuring instruments. Their pressure element is often referred to as a Bourdon tube: The French engineer Eugène Bourdon made use of this functional principle in the middle of the 19th century.
How Do Diaphragm Pressure Gauges Work? Hunker
A diaphragm pressure gauge is a device that uses a diaphragm with a known pressure to measure pressure in a fluid. It has many different uses, such as monitoring the pressure of a canister of gas, measuring atmospheric pressure, or recording the strength of the vacuum in a vacuum pump.
Common Tank Gauging Technologies and How They Work Varec
The liquid level in feet and inches or meters and decimeters is displayed on the gauge counter or indicated on a gauge board. This simple design and operation allows the gauge to perform with negligible maintenance throughout its working life. Varec servo tank gauges operate on the principle of displacement measurement. A small displacer on

Types of Level Gauges AutomationWiki
Types of Level Gauges . Several forms of level gauges exist in the industry. Depending upon the types of liquids such as water, oil, diesel etc. measured by level gauges, they can be classified into following categories: Tank level gauges: These level sensing devices generally determine volume of liquid enclosed in the tank.
