Soil Moisture Sensor working principle and applications

Posted by Nandan Technicals - March 10, 2021

Soil Moisture Sensor What is a Soil Moisture Sensor? The soil moisture sensor is one kind of sensor used to gauge the volumetric content of water within the soil. As the straight gravimetric dimension of soil moisture needs eliminating, drying, as well as sample weighting. These sensors measure the volumetric water content not directly with the help of some other rules of soil like dielectric constant, electrical resistance, otherwise interaction with neutrons, and replacement of the moisture content. The relation among the calculated property as well as moisture of soil should be adjusted & may change based on ecological factors like temperature, type of soil, otherwise electric conductivity. The microwave emission which is reflected can be influenced by the moisture of soil as well as mainly used in agriculture and remote sensing within hydrology. These sensors normally used to check volumetric water content, and another group of sensors calculates a new property of moisture wi

U-Tube Manometer

Posted by Nandan Technicals - August 14, 2021

monomers Manometer is a device used to measure pressure at a single or multiple points in a single or multiple pipelines, by balancing the fluid column by the same or another column of fluid. Manometers work by the principle that a column of fluid in a tube will rise or fall until its weight is in equilibrium with the pressure differential between the two ends of the tube. For a pressure difference P is the height difference h between the level of liquid in the two halves of the tube A and B, is given by the equation P = pgh, where p is the density of the fluid in the tube. U-Tube Manometer “A U-tube manometer, in which differential pressure is measured as the difference 'h' between the high-pressure reading and the low-pressure reading, multiplied by the density of the liquid in the tube.” The difference in height of the liquid represents the applied pressure. In U-tube manometer we measure the pressure as: P= sp wt * height( fluid)- sp wt * height( Hg) Introduction
