a.<\/b><\/span> Flow Sensors Based on Pressure Differences<\/b><\/span>
\n This method is based on Bernoulli’s Law which states the relationship:<\/span>
\n\"image\"<\/a>
\n Where:<\/span>
\n P = fluid pressure<\/span>
\n \u03c1 = period of fluid type<\/span>
\n v = speed of fulida<\/span>
\n g = Earth’s gravity<\/span>
\n h = high fluid (elevation)<\/span>

If h 1<\/sub> and h 2 are<\/sub> made equal in height then<\/span>
\n\"image\"<\/a>
\n Caution: The above formula applies only to Laminer<\/i> flows ,<\/i> ie streams that meet the principle of continuity.<\/span><\/p>\n

Pitot pipes, orifice plate, venturi pipe and flow Nozzle using Bernoulli’s law above.<\/span> The basic principle is to form a slight change of velocity from the fluid flow to obtain observable pressure changes.<\/span> The fluid flow velocity change can be made by changing the diameter of the pipe, this relationship is obtained from the fluid flow control law.<\/span><\/p>\n

Consider the following formula: A<\/i> 1<\/sub> .<\/span> D<\/i> 1<\/sub> = A<\/i> 2<\/sub> .<\/span> D2<\/i> , where: A = the cross-sectional area of \u200b\u200bthe pipe, B = the fluid discharge<\/span>
\n Since fluid flow is directly related to fluid velocity, it is clear that the fluid velocity can be changed by altering the diameter of the pipe.<\/span><\/p>\n

b.<\/b><\/span> Orifice Plate<\/b><\/span>
\n The measuring instrument consists of a pipe where the inside is given a hollow plate smaller than the diameter of the pipe.<\/span> Pressure sensor placed side of the inlet plate (P 1<\/sub> ) and one on the side of the outlet plate plate (P 2<\/sub> ).<\/span> If there is flow from the inlet to the outlet, then the pressure P 1<\/sub> will be greater than the outlet pressure P 2<\/sub> .<\/span><\/p>\n

The main advantages of this Orfice plate are from:<\/span>
\n 1. Simple construction<\/span>
\n 2. The size of the pipe can be made exactly the same as the size of the connection pipe.<\/span>
\n 3. The price of making the tool is quite cheap<\/span>
\n 4. Output is large enough<\/span><\/p>\n

The disadvantages of using this method are:<\/span>
\n 1. If there is a solid part of the fluid flow, then the solid part will be collected on the plate side of the inlet.<\/span>
\n 2. The reach of measurement is very low<\/span>
\n 3. Turbulent<\/i> flow may result in a measurement error so large because it does not follow the Laminer<\/i> flow principle .<\/i><\/span>
\n 4. Not possible when used to measure low pressure fluid flow.<\/span>
