I. Overview
Product Name: Ultrasonic Water Level Gauge
Nickname: Ultrasonic Surface Water Level Gauge
Basic description: SR30 ultrasonic water level gauge is a cost-effective sensor for measuring water level. HSC-SR30 water level gauge measures the distance from the probe to the surface of the measured target and intelligently calculates the height of the water level.
2、 Characteristics
1. Sturdy design and unique sand protection cover design;
2. Used in various harsh environments;
3. Accurate measurement and intelligent sensors;
4. High sensitivity and low power consumption;
5. Easy to install and maintenance free.
3、 Basic principles
The measurement principle of SR30 ultrasonic water level gauge is to emit an ultrasonic pulse and then receive the echo to measure the time of the propagation process. Because the propagation speed of ultrasound is constant at a certain temperature, this distance can be calculated by measuring the propagation time and air temperature. The sensor is equipped with a temperature sensor, and the temperature measured by this temperature sensor is used to correct the ultrasonic velocity. The distance measurement data can be output in ASCII code through the RS-232 serial port.
4、 Typical applications
1. Meteorological, hydrological and environmental monitoring
In response to the impact of natural and human factors on the meteorological and hydrological environment, the SR30 ultrasonic water level gauge provides real-time monitoring of water level changes, which can be used for water quality monitoring, flood warning, agricultural irrigation, aquaculture and other industries. At the same time, it can meet the needs of joint hydrological and meteorological monitoring networks, as well as the requirements of professional hydrological and meteorological observations.
2. Industry water level monitoring
In response to the needs of various industries such as agriculture, forestry, animal husbandry, construction, and energy, precipitation and water accumulation have important impacts on their industry characteristics. The SR30 ultrasonic water level gauge is an ideal tool for monitoring water levels.
