Measure the level or depth of water or other liquids.

Measure the level or depth of water or other liquids. is a detailed work activity in O*NET — a concrete unit of work shared across 10 occupations and seen in 11 occupation-specific tasks. It rolls up into the broader work activity Measure physical characteristics of materials, products, or equipment. in Estimating the Quantifiable Characteristics of Products, Events, or Information .

Detailed work activities are the most granular shared layer in O*NET's work-activity hierarchy (Generalized → Intermediate → Detailed → occupation-specific task). The figures below describe how this activity shows up across the economy and what independent studies measure about AI and this kind of work — not a prediction that the work will be automated.

AI exposure

Of the 11 tasks under this activity that the OpenAI / Eloundou “GPTs are GPTs” study rated, 1 (9%) are flagged as directly exposed to language models (E1) or exposed via model-powered tools (E2).

Exposure estimates overlap with model capabilities — whether a model could speed the task up — not whether the work will be done by software. Observed AI use is augmentation and assistance today, not jobs replaced.

Member tasks

Occupation-specific tasks O*NET maps to this detailed work activity, most important first.

• Inspect vehicles and check gas, oil, and water levels prior to departure. · Bus Drivers, Transit and Intercity · importance 4.5 · no direct exposure
• Observe water levels and oil, air, and steam pressure gauges to ensure proper operation of equipment. · Rail Yard Engineers, Dinkey Operators, and Hostlers · importance 4.5 · no direct exposure
• Measure depths of water, using depth-measuring equipment. · Captains, Mates, and Pilots of Water Vessels · importance 4.4 · no direct exposure
• Check tire pressure and levels of fuel, motor oil, transmission, radiator, battery, or other fluids, adding air or fluids as required. · Automotive and Watercraft Service Attendants · importance 4.2 · no direct exposure
• Tend vessels that store substances such as gases, liquids, slurries, or powdered materials, checking levels of substances by using calibrated rods or by reading mercury gauges and tank charts. · Pump Operators, Except Wellhead Pumpers · importance 4.2 · no direct exposure
• Lower gauge rods into tanks or read meters to verify contents, temperatures, and volumes of liquid loads. · Tank Car, Truck, and Ship Loaders · importance 3.9 · no direct exposure
• Read draft markings to determine depths of vessels in water. · Transportation Inspectors · importance 3.8 · exposure with tools
• Take depth soundings in turning basins. · Motorboat Operators · importance 3.6 · no direct exposure
• Measure depth of water in shallow or unfamiliar waters, using leadlines, and telephone or shout depth information to vessel bridges. · Sailors and Marine Oilers · importance 2.9 · no direct exposure
• Measure the properties of bodies of water, such as water levels, volume, and flow. · Hydrologic Technicians · no direct exposure
• Measure vessels' holds and depths of fuel and water in tanks, using sounding lines and tape measures. · Transportation Inspectors · no direct exposure
