1. Current meters indicate such minimal currents that the bay can be considered essentially stagnant.2. Voltage withstand testing is done with a high voltage source and voltage and current meters . 3. Fourthly, current meters were used to measure and record water flow within the project area. 4. Here the sounding machine is used to set a Pillsbury current meter at a known depth. 5. During the 1892 summer break, both brothers vacationed in the Ausable River with various current meters . 6. Note caption on photo : " Sounding Machine And Current Meter In Place, Steamer " Blake "" 7. The "'Ekman current meter "'is a mechanical flowmeter invented by Vagn Walfrid Ekman, a Swedish oceanographer, in 1903. 8. This was followed in 1926 by Cecil Aggeler's bachelor's thesis, " Design of a Venturi Type Current Meter ." 9. A single current meter is at 10 m, and surface meteorological sensors are mounted on the tower of the mooring. 10. Velocity is measured by using a current meter with a propeller that is rotated by the action of flowing water.
