The C2 Small Current Meter is used for measurement of flow velocity at low water levels.
The highly precise, reinforced spindle bearing as well as a non-contact signalling system give the possibility for measuring flow velocities as of 0.025 m/s. Minimum depth of water for the C2 is approx. 4 cm.
The OTT C2 Small Current Meter is used for flow velocity measurement at low water levels in:
Small channels, falajs
Cost reduction owing to low maintenance requirements and simple, inexpensive handling.
The robust construction and high-quality materials allow operation even under difficult conditions with high accuracy
Low starting speed due to robust ball bearings
Reinforced meter spindle
Flow velocity from 0.025 m/s to 5 m/s
Current meter reed relay contact 1 pulse/revolution lifetime > 1 million contacts
Operating voltage range max. 9V DC
Magnetic switch pressure-tight up to 30 bar
Material - meter body brass - gal Ni 8mt
Material - propellor aluminium, anodised
Size dia. x length up to tip of propeller ø14 x 152 mm
Weight w/o propellor 0.103 kg
Rod w/o clamping piece ø9mm, with clamping piece ø20mm
The rotation rate of the precisely calibrated propeller is proportional to water velocity. The velocity is determined by counting the number of propeller revolutions over a pre-selected time period with a counter unit.
