Dayu Electronics Ultrasonic Level Meter for Non-Contact Measurement

　　Dayu Electronics ultrasonic level/solid level meter uses ultrasonic pulse principle for non-contact measurement. It is non-contact, easy to install and maintain, and widely used in remote locations such as fields, reservoirs, ponds, and mountains where power supply is inconvenient. The ultrasonic level meter has a small emission angle, making it suitable for confined spaces. With a 5-minute sampling interval, the battery can last up to 2 years, saving costs, and it is supplied directly by the manufacturer. It can meet most level measurement requirements without contacting the medium, integrating functions such as level measurement, distance display, and transmission. The measured medium is almost unrestricted, and it can be widely used for height measurement of various liquids and solid materials.

　　In Ningde City, the user needed to measure the water level changes before and after the sluice gate using an ultrasonic level meter. The collected data is used to calculate the drainage flow of aquaculture and the seawater flow for farming. Because the ultrasonic level meter can accurately calculate the water volume, flow rate, pressure, etc., based on water level data, it is very important for sluice gate opening and closing scheduling, measuring water body capacity, and measuring upstream and downstream flow velocities of the gate body, effectively ensuring the safety of aquaculture. Currently, level meters are widely used in water level measurement. The main types of level meters include: magnetic flap level meters, ultrasonic level meters, radar level meters, laser level meters, etc. Ultrasonic level meters, with advantages such as being economical and practical, easy installation, non-contact measurement, wide adaptability, and not affected by sludge blockage, scouring, or liquid corrosion, are very suitable for water level measurement in sluice gate projects. In addition, the water flow in that area is stable for a long time with small water level differences, so it was finally decided to use an ultrasonic level meter.

　　When selecting an ultrasonic level meter, attention should be paid to whether its range meets the actual needs to avoid exceeding the measurement range. In practical applications, because the water flow near the gate fluctuates greatly when the gate is opened or closed, which can easily cause inaccurate measurements, it is generally not recommended to install the ultrasonic level meter close to the gate. Instead, it should be installed in a place with gentle water flow, away from floating debris and boats. In addition, the design warning water level of the sluice gate project should be considered to avoid submerging the equipment when the water level is too high, which could cause malfunctions and affect measurement.

　　Dayu Electronics ultrasonic level meters have good sealing and a protection rating of up to IP68. Their excellent waterproof capability effectively protects the instrument, preventing water mist and dust from entering. Even if the water level rises and submerges the instrument, it will not be damaged in a short time, making it very suitable for water level monitoring in sluice gate projects.
