The prefix ' iso ' is a greek word meaning equal, so an isoline must be a line joining equal points. Standard age-height-weight tables derived from life insurance data often incorrectly indicate individuals to be overweight. A wide variety of models is available, including Laser Sensors, LED Sensors, Ultrasonic Sensors, Contact Sensors, Eddy Current Sensors, and more. 5 for curtains that are drapey even when closed. Since static fluid pressure is determined by the fluid density and depth, the depth or height difference of a given liquid is commonly used for pressure measurement: The fact that the liquid levels are the same in these three manometers shows that the pressure in the glass manifold above them is uniform. 6 Attribute Measurement Level Operations. This difference is the amount of drop you need in your ball mount. • When the difference in elevation along the measurement becomes too great for level chaining, other methods are called for.
