The volume of lng before and after cargo measurement is determined with three decimal places. It contains articles on integrated lng management. Non invasive flow measurement with ultrasound is an elegant alternative to classical invasive measurement techniques. Quick reference guide for body cab to axle the most crucial measurement in the truck equipment installation process is the cab to axle. Lng may be classified taking into account several criteria. Normally its density is the most usual parameter used for classification.
The thermally separated ultrasonic transducers offer a reliable and proven way to measure lng flows without causing any pressure drop. Table nº 1 presents three typical lng qualities due to its density. Thus is spoken of heavy or light lngs. Lng level type of lng level gauge used are float gauges displacement gauges and radar gauge. This is abbreviated as mmt or more commonly mt. Yesterday we highlighted the role of mass based flow measurement in liquefied natural gas lng custody transfer applications.
For tandem axle applications the measurement is back of the cab to center of tandems trunnion known as ct. The 5900s with lng antenna measures the liquid level with an instrument accuracy of 05 mm 0020 in. However the lng industry uses mt to represent million tons. This is the measurement from the back of the cab to the center of the drive axle. Density heat value wobbe index methane or nitrogen amount etc. Lng and gas quality and measurement manual.
The net volume of transferred lng is the difference between these measurements and is taken with three decimal places for calculating the energy. Ill point the lng tank gauging news email message i received a while back. Produced gas is measured in volume cubic meters or cubic feet but once it is converted into lng it is measured in mass units usually tons or million tons. So you are not particularly curvy your waist is not well defined and your weight is fairly distributed throughout the bodythis shape of the body is also called as the straight or ruler body. The lng temperature measured in the lng carriers tanks. The temperature of lng is measured in c to one 1 decimal place eg 01.
Million tons should technically be abbreviated mmt. It is virtually maintenance free accuracy approved according to oiml and sil 2 and sil 3 certified. Today i wanted to highlight the role of radar tank gauging technology in lng tank storage applications. The flow meter must withstand and measure high vapor evolution during lng tank rollover. The calculation should use the revised klosek and mckinley kmk1method for determining lng density. Rectangle a rectangle is a woman whose body shape means having waist measurements that are less than 9 inches smaller than the hip or bust measurements.
