MODEL SLY_(1-1) ACOUSTIC DOPPLER CURRENT METER

本文介绍了SLY_(1-1)型声学多普勒海流计的工作原理、仪器结构、电路设计、主要技术性能和仪器特点,叙述了仪器在检定水槽和海上的试验情况。

Acoustic Doppler current meter,model SLY1-1 developed in this institute,measures current velocity and direction,and sound velocity in water.The sensor for measure ment of current velocity is two transdusers and that of current direction is a small potentiomcter compass.The meter consists of two sections:the sensor anl signal processing display unit.The data measured are displayed on nixie tubes data read out directly and fast reading out of data.The meter has the features of direct and simple operasion.The principle of the current meter,the structure of sensor,the circuit designed and data from the calibration tank and the field are given in the paper too.The results shov that in the range of 0.01—1.50m/s,the error is less then±1%on conditions of full scale.
