The proper use of a color convention when developing an HMI is becoming more prevalent and is the subject of years of research, study, and even Learn how to program PLCs, install and wire industrial devices, and at the same time purchase them online. Manometer Explained Manometer Working Principle Learn about manometer which is one of the most accurate devices for measuring pressure in the lower ranges.
A manometer is one of the most accurate devices for measuring pressure in the lower ranges. Since manometers are so accurate, they are often used as calibration standards.
Manometer applications. Some typical industrial manometer applications include: — Fluid flow measurements — HVAC systems maintenance — Residential or commercial furnace gas valve pressure measurement. Manometer basics. There are several different types of manometers and we will discuss many in this article.
Types of manometer. Types of fluids. Quite often the liquid is colored to help detect the fluid movement. Measuring pressure. Increasing measurement accuracy. What if we wanted to accurately measure very low-pressure values? Upcoming SlideShare. Like this document? Why not share! Embed Size px. Start on. Show related SlideShares at end.

Raised wells can be furnished so positive and negative pressures or reversing flow can be indicated without changing the pressure connections. Various mounting styles to satisfy installation requirements are available.
The manometer body is of aluminum channel construction. Stainless steel end blocks, for packing the glass indicating tube, are screwed to the body.
The welded stainless steel manometer well has a large cross section and is readily removable for greatest ease in cleaning. The unit scale, located directly behind the glass indicating tube, extends the full width of the instrument body and is graduated on each side of the indicating column. This scale has a white, non-glare satin background with black graduations and figures, and is compensated for liquid level change within the manometer well. The scale is adjustable for zero indicating fluid level by means of a non-slip, flexible shaft adjustment located in the lower end block and operated from the front of the instrument.
A transparent plexiglass cover protects the unit from dust and moisture. All exterior portions of the manometer are finished in textured, black urethane paint. A piezometer tube is used only for measuring. The primary standard for calibrating vacuum is:. Sensitivity of U-tube manometer with inclined leg depends on:. To measure very high pressure a pressure gauge used is -. The device used for measuring the pressure at a point in a fluid by balancing the column of fluid by the same or another column of the fluid is known as:.
Which of the following devices is used to measure fluid pressure? More Pressure Measurement Questions Q1. Pressure variation of air above sea level is:. The gauge pressure in a liquid at a depth of 3 m is read to be 28 kPa. The gauge pressure in the same liquid at the depth of 12 m will be:. What is the water pressure on the sea bottom at a depth of m? The specific gravity of sea water is assumed to be 1. Blood pressure is measured by mercury manometer and a stethoscope by wrapping a closed air-filled jacket around the upper arm of a person at the level of the heart.
These values are expressed in:. At sea level, under normal conditions, what is the atmospheric pressure?
