Difference between AC tachogenerator and DC tachogenerator
AC tachogenerator DC tachogenerator The AC tachogenerator is use to measure speed only in one direction only. The DC tachogenerator is use to measure speed in both direction. It consists of a stator and a rotor arrangement
What is electromagnetic flow meter?
Electromagnetic flow meters are particularly suitable for the flow measurement of slurries, sludge and any electrically conducting liquids. A constructional diagram of electromagnetic flow meter is shown in above figure. It consist of a pair of
Working principle of ultrasonic level detector
This method is based upon utilization of law of reflection of ultrasonic oscillation from solid or liquid surfaces or from the interface between two immiscible liquids. The time taken by the wave for its travel from transmitter

Bourdon tube
It consists of seamless metal tubing having elliptical cross section. The tube is enclosed in a socket which contains pressure inlet. One end of the tube is sealed and the other end is open to apply the
Advantages and disadvantages of RTD (resistance temperature detector)
Advantages: There are some advantages of RTD (resistance temperature detector) which are given below, The RTD can be easily installed and replaced. It is available in wide range. The RTD can be used to measure differential temperature.
Difference between venture tube and orifice plate
Venture tube Orifice plate The venture tube consist of three parts i.e. inlet cone, throat and outlet cone. The orifice plate is a thin circular plate. The venture tube is made up of cast iron or steel.
Resistance temperature detector (RTD)
The thermometer in which the resistance of conductor changes with change in temperature is known as resistance thermometer. The resistance thermometer is also called as resistance temperature detector (RTD). Construction: The resistance temperature detector (RTD) consists of
Construction and working of RVDT (Rotary variable differential transformer)
The RVDT stand for rotary variable differential transformer is used to sense the angular displacement. It is similar to LVDT except that its core is in cam shaped and moves between the windings by means of shaft.
