A lightning arrester is a device that provides a low-impedance path to ground for lightning or transient overvoltages, effectively protecting the electrical system from high-voltage surges. It operates by limiting the voltage across its terminals to a safe value and shunting the excess energy to the ground. What is a Lightning Arrester? A lightning arrester, […]
An Energy Meter, also known as a watt-hour meter, is an electrical device used to measure the amount of electrical energy consumed by a residence, business, or electrically-powered device. The energy is typically measured in kilowatt-hours (kWh), which is the standard billing unit for energy consumption.
A Pitot tube is a commonly used variable head, fluid velocity measuring device. It is also called as Pitot static tube or air speed indicator (in aircraft). Figure 1: Pitot Tube.

A turbine flow meter is a device used to measure the flow rate of a fluid (liquid or gas) by converting the kinetic energy of the fluid into rotational motion of a turbine. The flow rate is proportional to the rotational speed of the turbine. Figure 1: Turbine Flow Meter.
The McLeod gauge is used for measuring pressures ranging from 0.01 micron to 1 mm of Hg. Figure 1: McLeod Gauge.

In rotameter, the area of flow is measured in such a way that the head differential is constant. Hence rotameter is called variable area meter or area meter. Rotameters are widely used for metering purge flows, pump-seal fluid and coolants and lubricants for operating machinery. Figure 1: Rotameter.
