Operational Amplifiers Questions & Answers
1. Explain what is an operational amplifier? An operational amplifier, abbreviated as op-amp, is basically a multi-stage, very high gain, direct-coupled, negative feedback amplifier that uses voltage shunt feedback to…
Basics of Electromagnetic compatibility (EMC)
The measuring electronics of field transmitters like flowmeters are constantly becoming more efficient and more compact. Digital data processing with its microprocessors has opened up new avenues for new communications,…
Difference between TCP/IP Model and OSI Model
TCP/IP is the communication protocol to connect hosts to the Internet, while OSI is a reference model for communication between end users in the network. Transmission Control Protocol is used…
Difference Between LAN and WAN Networks
The two most popular network types today are LAN (Local Area Network) and WAN (Wide Area Network). These two networks are generally classified on the basis of their coverage area.…
Annubar Flow Meter – Principle, Advantages, Disadvantages
Annubar flow meter are sometimes referred to as Averaging pitot tubes and contain multiple pressure tappings to measure average of the flow rate.
Dall Tube Flow Meter – Principle, Advantages, Disadvantages
Dall tube is shortened version of Venturi meter, with a lower pressure drop than orifice plate. Flow rate is determined by measuring pressure drop.
V Cone Flow Meter – Principle, Advantages, Disadvantages
V Cone flow meter is a differential pressure (DP) meter. These flow meters all work according to the same principle of DP flow sensors or devices.
Venturi Flow Meter – Working Principle, Advantages, Animation
When venturi flow meter is placed in a pipe carrying the fluid whose flow rate is to be measured, a pressure drop occurs across venturi meter.
What is Differential Pressure Flow Meter?
A differential pressure flow meter works on the principle of partially obstructing the flow in the pipe and measures the flow rate based on DP.
How to Select a Flow Meter
Selecting Magflow Flow Meters he main questions which need to be considered before selecting a magnetic flow meter: - Is the fluid conductive or water based? - Is the fluid…
