Ultrasonic Level Meter Applied in Wastewater Tank Level Measurement at a Photovoltaic Enterprise [Dayu Electronics]
Ultrasonic level meter is a digital level instrument controlled by a microprocessor. During measurement, pulse ultrasonic waves are emitted by the sensor (transducer), reflected by the surface of the object, and received by the same sensor, where they are converted into electrical signals. The distance from the sensor to the measured object is calculated based on the time between transmission and reception of the sound waves. Due to non-contact measurement, the measured medium is almost unrestricted, making it widely applicable for measuring the height of various liquids and solid materials.
Features of the ultrasonic level meter:
1. LCD dot-matrix display with Chinese/English text, simple operation
2. Precision filtering algorithm to eliminate false measurements
3. Multiple algorithm options for different working conditions to ensure measurement accuracy
4. Piezoelectric surge protection
5. Automatic sound speed and temperature compensation
6. Echo curve display for on-site debugging and fault detection
7. Self-diagnostic function with rich diagnostic information for convenient maintenance and debugging
8. Independent password function with different levels of passwords for factory and calibration settings, facilitating management
9. Multiple display units available
How to select an ultrasonic level meter for a wastewater tank: First, check the height of the tank and the typical liquid level to determine the measurement range of the ultrasonic level meter. Then, based on the characteristics of the wastewater, determine whether a corrosion-resistant ultrasonic level meter is needed. Finally, based on the on-site working conditions, determine the structure, power supply, and output of the ultrasonic level meter.
How to install an ultrasonic level meter for a wastewater tank: Since most wastewater tanks are exposed outdoors, protective measures should be taken during installation. The main unit should be shielded from direct sunlight and rain. Additionally, the installation location should be chosen carefully—it should be placed where the liquid level is stable, away from water inlets and outlets. Furthermore, a bracket mounting method should be used to secure the ultrasonic level meter firmly, and it should not be placed too close to walls to avoid ultrasonic waves reflecting back from walls and causing data confusion.
