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.

Figure 1: Bellows Pressure Gauge. Working and Construction of Bellows Pressure Gauge The bellows pressuree gauges are used for the measurement of absolute pressure. It is more sensitive than Bourdon tube gauges. It is generally used for the range down to 155.1 mm Hg (3 psi). It may be used for even lower pressures upto

Figure 1: Float Level Sensor. Working and Construction of Float Level Sensor The float type level indicator is shown in Fig. 1. A float rests on the surface of liquid and follows the changing level of liquid. The movement of the float is transmitted to the pointer by a stainless steel or phosphor-bronze flexible cable
