Editing Telemetry (section)

====Fluids====
Fluids stored in tanks are a principal object of constant commercial telemetry. This typically includes monitoring of tank farms in gasoline refineries and chemical plants—and distributed or remote tanks, which must be replenished when empty (as with gas station storage tanks, home heating oil tanks, or ag-chemical tanks at farms), or emptied when full (as with production from oil wells, accumulated waste products, and newly produced fluids).<ref name="remote_tank_monitoring_2019_03_tanktransport_com">Rues, Gerald, MSEE, [http://tanktransport.com/2019/03/remote-tank-monitors-can-save-time-and-money/ "Remote Tank Monitoring Can Save Time and Money,"] {{Webarchive|url=https://web.archive.org/web/20190307175226/http://tanktransport.com/2019/03/remote-tank-monitors-can-save-time-and-money/ |date=2019-03-07 }} March, 2019, ''[http://pubhtml5.com/cgnb/twxm/ Tank Transport] {{Webarchive|url=https://web.archive.org/web/20190307054559/http://pubhtml5.com/cgnb/twxm/ |date=2019-03-07 }},'' magazine, retrieved March 6, 2019</ref> Telemetry is used to communicate the variable measurements of flow and tank level sensors detecting fluid movements and/or volumes by [[pneumatic]], [[hydrostatic]], or differential pressure;  tank-confined [[Ultrasound|ultrasonic]], [[radar]] or [[Doppler effect]] echoes; or mechanical or magnetic sensors.<ref name="remote_tank_monitoring_2019_03_tanktransport_com" /><ref name="esi_tank_sensors">[http://www.leveldevilsensors.com/main/electronic-sensors-inc-esi-level-devil-american-made-tank-monitors-and-tank-monitoring-systems/tabk-sensor/ Tank Sensors & Probes] {{Webarchive|url=https://web.archive.org/web/20190318111356/http://www.leveldevilsensors.com/main/electronic-sensors-inc-esi-level-devil-american-made-tank-monitors-and-tank-monitoring-systems/tabk-sensor/ |date=2019-03-18 }}, Electronic Sensors, Inc., retrieved August 8, 2018</ref><ref name="dozen_ways_2004_dec_1_sensormag_com">Henry Hopper, [https://www.sensorsmag.com/components/a-dozen-ways-to-measure-fluid-level-and-how-they-work "A Dozen Ways to Measure Fluid Level and How They Work,"] {{Webarchive|url=https://web.archive.org/web/20190330163148/https://www.sensorsmag.com/components/a-dozen-ways-to-measure-fluid-level-and-how-they-work |date=2019-03-30 }} December 1, 2018, ''Sensors Magazine,'' retrieved August 29, 2018</ref>
