Eugen Gassmann WIKA Instruments Introduction to Pressure Measurement Mechanical pressure measurement Indicating pressure gauges for gauge, absolute and differential pressure with Bourdon tube, diaphragm or capsule pressure elements have been tested millions of times over. Orifice Plate or Orifice Meter: An orifice meter is another device to gauge the flow of a liquid through … Here we will see different types of pressure measurement instrument.. Introduction. These instruments cover scale ranges from 0 … 0.5 mbar to 0 … 7,000 bar and indication accuracies of up to 0.1 %. Thus gauge pressures fluctuate with changes in atmo­ spheric pressure. Here will show the detailed function of all pressure measuring devices.We will also see the working and operating principle of pressure measuring device also. There are several common terms associated with pressure measurement devices that are often used interchangeably. The entire pressure measurement system is constituted by a primary element, which will be in direct or indirect contact with the process where the pressure changes occur, and a secondary element (the pressure transmitter) whose task will be translating the change in measurable values for use in indication, monitoring and control. It is the best quick indication of the work done by pumps and compressors. There is a large market for blood pressure measuring devices not only in clinical medicine but also among the public where the demand for self measurement of blood pressure is growing rapidly. Measurement of blood pressure is an important diagnostic and monitoring procedure. Today we will understand here the basic concept behind the measurement of pressure at a point in fluid in the subject of fluid mechanics with the help of this post.

The chance to reduce the risk of heart attack or stroke could also be missed. 845 0 obj <> endobj Manufacturers and suppliers of these devices may use one or more of these terms to describe their product offerings. Measured above total vacuum or zero absolute. We will also secure here the various types of devices used for pressure measurement. Optical techniques (Laser Doppler) Single phase flows Two phase flows 1. Further, we will see each type of pressure measuring device … Pressure measurement 2 pressure: vented gauge (vg) and sealed gauge (sg). The manometer mechanism applies the measured pressure to a column of liquid and the variation in the liquid level is measured. A gauge is often used to measure the pressure difference between a system and the surrounding atmosphere. Download Pressure And Pressure Measuring Devices Assignment. Devices for Office / Clinic blood pressure measurement Preferred devices (10) Microlife WatchBP Office Omron HBP-1300 The gauge uses a unit of measurement called millimeters of mercury (mmHg) to measure the pressure in your blood vessels. These short objective type questions with answers are very important for Board exams as well as competitive exams.
