20. Water Level Measurement Water level is determined by using a vertical beam and integrated pressure sensar The vertical beam sends short sound pulse and listens for the reflection from the sur fice The surface reflection is very strong and clearly defined allowing the IQ to precisely measure the time at which the retur reflection is received To convert the reflection time to surface range the IQ needs to know the speed of sound in the water at the survey site which is primarily a function of temperature and salinity The IQ s internal temperature sensor automatically compensates far changing condi tions by continually updating the sound speed used for surface range calculations Salinity is user defined ie the 10 does not automatically adjust for salinity varin tions SonTak IG Users Manual November 2011 SonTek a Xylem brand The vertical beam also works under ice measuring the range to the bottom of the ice this gives water depth beneath the ice as needed for discharge monitoring The vertical beam can operate with water depths from 0 08 to 1 5 m above the transduc er for the IQ Standard and 0 08 to 5 m for the IQ plus The vertical beam works in conjunction with the integrated pressure sensor to determine water level The vertical beam is the principle measurement 2 The pressure sensor is used as a secondary measurement in the case that there is not data from the vertical bea
