The removable well is bolted to the back plate and connected to the glass tube through the lower end block. The scale with satin background, bold black figures, and precision graduations spans the full channel width behind the indicating tube. Scale and tube are protected by a transparent cover.

Each Model 40HEX35 is individually calibrated and the angle of inclination is set relative to the instrument level mounted above the channel.

The instrument finish is black textured urethane. The Meriam Model 30EBX25 and 30EFX25 well type manometer are direct reading manometers designed for process, general purpose production testing, or laboratory measurement of pressures, vacuums or differential pressures. 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 manometer's inclined angle provides many advantages. A small or low amount of pressure against the inclined manometer will produce a large liquid movement relative to the tube's graduations. As a result, the graduation scale can be very precise--down to a hundredth of an inch accuracy.

In addition, the inclined manometer's simple design makes it an inexpensive, but accurate, tool for everyday gas-pressure measurement. Other manometer tools, such as the U Type, cannot register low-pressure quantities. The inclined manometer is essential for retaining the most accurate pressure levels for industrial gas applications.

A low-pressure industrial gas system may be used to heat or cool manufacturing processes. A small blockage within the gas system can be detected with an inclined manometer and corrected. Other manometer types may not register the small blockage until the gas system becomes completely clogged, warranting a possibly costly repair. The high accuracy of the inclined manometer makes it a precise tool for calibrating other tools, such as a specific pressure needed in an air-conditioning unit.

The worker can place the inclined manometer into the air conditioner's air pressure flow. A U - tube manometer. A manometer is used for the pressure measurement in a closed tank. The schematic arrangement with manometric reading and other dimensions are shown in the figure. The figures show the cross-section of an oil pipe with a manometer attached. On the right side of the manometer, the manometer fluid is in contact with oil, and on the left side, the manometer is open to the atmosphere.

The oil has a specific gravity of 0. What is the gauge pressure at the center of the pipe if hm is 10 cm and ho is 5 cm? 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:.
