n: The tubular sub connected below or above DSTT packer. Used to protect manometer when tripping.

a device that measures the density of fluids along a fluid column.

n: a scale for measuring small increases or decreases in pressure. usually in conjunction with a manometer, a U-tube containing mercury. Pressure on one side of the U-tube causes the mercury to move upward on the other side. The movement is measured in inches or millimetres. See manometer.

n: a scale for measuring small increases or decreases in pressure, usually in conjunction with a manometer, a U-tube containing water. Pressure on one side of the U-tube causes the water to move upward on the other side. The movement is measured in inches or milli- metres. See manometer.

n: a U-shaped piece of glass tubing containing a liquid (usually water or mercury) that is used to measure the pressure of gases or liquids. When pressure is applied, the liquid level in one arm rises while the level in the other drops. A set of calibrated markings beside one of the arms permits a pressure reading to be taken, usually in inches or millimetres.

n: a meter that uses a Pitot tube and a manometer or other differential- pressure mechanism to measure flowing fluids. The difference between the pressure on the Pitot tube and the static pressure is the velocity of the flow, which is directly related to the rate of flow.
