However, after emptying the tank into jerry cans, I measured the capacity to be 60 gallons. While measuring the capacity, I also calibrated a Simrad Fluid Level Sensor model 000-11518-001. The process involved adding ten gallons at a time and measuring the resistivity of the sending unit:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><tbody><tr><td>Volume (Gallons)<\/td><td>Resistivity (Ohms)<\/td><\/tr><tr><td>0<\/td><td>255<\/td><\/tr><tr><td>10<\/td><td>193<\/td><\/tr><tr><td>20<\/td><td>127<\/td><\/tr><tr><td>30<\/td><td>98<\/td><\/tr><tr><td>40<\/td><td>70<\/td><\/tr><tr><td>50<\/td><td>51<\/td><\/tr><tr><td>60<\/td><td>42<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Note the change in resistivity is not linear. This is due in part to the non-linear behavior of the sending unit, but mostly due to the V-shape of the fuel tank. Without calibration, a &#8220;half tank&#8221; according to the mechanical gauge was probably in fact about a quarter tank. Having used five points to calibrate the Fluid Sensor (Empty, 1\/4, 1\/2, 3\/4, and Full), it presumably gives a more accurate measurement of the fuel volume (highlighted in red).<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" width=\"525\" height=\"306\" src=\"https:\/\/i0.wp.com\/aegir-ran.com\/wp-content\/uploads\/2023\/10\/IMG_1235.jpg?resize=525%2C306&#038;ssl=1\" alt=\"\" class=\"wp-image-786\" srcset=\"https:\/\/i0.wp.com\/aegir-ran.com\/wp-content\/uploads\/2023\/10\/IMG_1235.jpg?w=1000&amp;ssl=1 1000w, https:\/\/i0.wp.com\/aegir-ran.com\/wp-content\/uploads\/2023\/10\/IMG_1235.jpg?resize=300%2C175&amp;ssl=1 300w, https:\/\/i0.wp.com\/aegir-ran.com\/wp-content\/uploads\/2023\/10\/IMG_1235.jpg?resize=768%2C447&amp;ssl=1 768w\" sizes=\"auto, (max-width: 767px) 89vw, (max-width: 1000px) 54vw, (max-width: 1071px) 543px, 580px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"> <\/p>\n","protected":false},"excerpt":{"rendered":"<p>The specs for an Alajuela 38 claim a fuel capacity of 75 gallon.
