Absolute instruments and secondary instruments are the two basic classifications of measuring instruments. You may be wondering why a tangent galvanometer is an absolute instrument while an ammeter is considered …
A flow meter measures the flow of liquids or gases – simple, right? Actually, no. But it’s the incredible diversity of this exciting and rapidly evolving technological field that makes …
What is DC Ammeter? A DC ammeter is the instrument used for measuring the direct current (DC) flowing through an electrical circuit and is connected in series to the circuit …
There are several types of flow meters in the market these days. Most of them use complicated technologies to measure the volumetric flow, linear, nonlinear, and the mass flow rate …
In this article, you will learn about four different types of damping systems namely air friction damping, fluid friction damping, eddy current damping and electromagnetic damping. Before going into the …
The electrodynamometer is a transfer-type instrument. A transfer-type instrument is one that may be calibrated with a dc source and then used without modification to measure AC. This requires the …
The most common ammeters and voltmeters for laboratory or switch-board use at power frequencies are the moving iron instruments. These instruments can be constructed to measure current and voltage to …
