Measurement of low level velocities for shallow bodies of water : project technical completion report by Jeffrey P Laible( Book )

2 editions published in 1984 in English and held by 4 WorldCat member libraries worldwide

The development of a low cost, low velocity (0-15 cm/sec) current meter is described. Several low velocity current measurement techniques are also surveyed. The developed current meter uses a thermistor, operating in a low overheat quasi-constant current mode, as the flow sensor. Velocity is determined by measuring the thermistor bead temperature by measuring the time to charge a capacitor through the thermistor between two known voltage levels. The useable velocity range was found to be 0-5 cm/sec making the probe useful for near bottom sampling but not for open flow situations. The developed current meter is very low in cost, has a low power requirement and is suitable for remote operation
