Add date: Million of Chongqing of 2008-10-10 continent the working principle of the ultrasonic fathometer that limited company of development of science and technology produces is to use transducer to give out ultrasonic in water, when sound wave encounters fraise and reflection answers transducer, according to sound wave roundtrip time and place measure the speed that the sound wave in water area transmits, can get the distance between fraise and transducer. Ultrasonic fathometer can be in ship voyage measure depth of water well and truly continuously quickly. Path of investigation of landform of path survey, benthic, sea measures commonly used Yu Hang and ship navigation fixed position.
Main characteristic
* gains ground cheap and finely model ultrasonic fathometer
In * , outside small-sized shipboard (inside) press outfit, cable 10 meters
* weight 400 grams
* basically is used on the sea, river, lake to underwater locates and measure depth of water.
The tall speek of a ship or plane with admirable * works, speek of a ship or plane 55 (63MPH)
* can install fluctuation to be restricted arbitrarily node and online output adjust
