A hot wire anemometer is a temperature transducer used for measuring flow rate. When the electrically heated temperature sensor is placed in a flowing fluid, heat is transferred from the sensor to the fluid. Hence the temperature of the sensor reduces resulting in a change in resistance of the wire. The amount of cooling of …
Flow meters are the devices used for measuring the flow rate of liquids or gases. Flow rate can be defined as the volume of fluid flowing through an area in unit time. In a pipe, the flow rate can be expressed in terms of speed of the fluid and the cross-sectional area of the pipe. …
Flow meters are the devices used for measuring the flow rate of liquids or gases. They work on Bernoulli’s principle and continuity equation. The Continuity equation The continuity equation represents that the product of the cross-sectional area of the pipe and the velocity of the fluid at any point is always a constant. Consider the …

A level transducer is a device that produces an electric signal with respect to a liquid level. Level transducers are classified based on following measurement methods Direct and indirect level measurements. Continuous and discrete level measurements. In direct method of measurement, the liquid level is converted directly to electrical signal. This can be done with …
A pressure transducer is a device that converts pressure into an analog electrical signal. Measuring Pressure Pressure is measured in three forms. Absolute pressure is a pressure that is relative to the zero pressure in a vacuum. Gage pressure is the pressure relative to atmospheric pressure. Differential pressure is the difference in pressure at two …
