Portable Ultrasonic Water Depth Meter - 1

MANUAL HOLYKELL TECHNOLOGY COMPANY LIMITED Portable Ultrasonic Water Depth Meter---HLU-SF 1. Profiles: Holykell HLU-SF ultrasonic water depth meter is used in reservoirs, lakes, rivers or shallow sea water etc. The main principal is to place ultrasonic transducer above water or in water and use ultrasonic spreading in the water to get calculated water depth by instrument. This instrument adopts the international advanced technology, equipped also with water depth measurement functions, control functions, data transfer functions and man-machine communication capabilities. This instrument is a water depth measurement instrument of ultrasonic receive and dispatch sensor, servo circuit, temperature compensation, salinity compensation and compensation circuit unit, monitor, and control signal output and serial data or analog output unit (optional). Its main advantages are high reliability, long life, easy access, simple operation, accurate measurement of features and less-maintenance, it has already been widely used in the hydrographic survey, hydropower plant, reservoir area, shallow seas, lakes, rivers, surveying, environmental waters monitoring etc. ■ the water depth meter has different compensation of water quality and water sound temperature for sea water, river water, and cost performance are surpassed import type. ■Standard configuration of instrument: 1. Sensor; 2. handheld instrument, high-capacity lithium-ion battery (built-in), 3.Dedicated charger. Can be selected a variety of portable protective box when you ordering.
