ZYW612 Ultrasonic Mud Water Interface Instrument

Product Details

Ultrasonic level gauges draw on the strengths of various level gauges both domestically and internationally. A universal level gauge that implements a fully digital and humanized design concept, with complete level measurement and control, data transmission, and human-machine communication functions. The transducer adopts original German components, and the main chip adopts imported industrial grade microcontrollers, digital temperature compensation and other related specialized integrated circuits. It has strong anti-interference ability, can freely set upper and lower limit nodes and online output adjustment, and has on-site display, analog quantity, switch quantity and RS485 output options, which can be easily connected to the host. The shell of the ultrasonic level gauge adopts a waterproof shell, and its circuit board uses high-quality surface mount components and a surface mount keyboard, making the product performance more stable and reliable.
ZYW612 ultrasonic mud water interface meter is a professional instrument for continuous measurement of sludge interface in sewage treatment process. By utilizing the principle of ultrasonic echo detection, the distance between the sensor probe and the sludge interface and the distance to the bottom surface are detected, and the thickness changes of the sludge are monitored in real time, thereby optimizing the sludge discharge control and dosing control, and optimizing the process flow.

The level gauge consists of an ultrasonic probe and an electronic unit designed as one unit. The level gauge is installed on the upper part of the container, and under the control of the electronic unit, the probe emits a beam of ultrasonic pulses towards the measured object. Sound waves are reflected by the surface of an object, and some of the reflected echoes are received by the probe and converted into electrical signals. The time from ultrasonic emission to re reception is proportional to the distance between the probe and the object being measured. The electronic unit detects the time and calculates the measured distance based on the known sound speed. The level value can be obtained through subtraction operation.

The propagation speed of ultrasound in gas is affected by the gas temperature, so the level gauge needs to detect the gas temperature and compensate for the sound velocity to ensure measurement accuracy. When the level gauge emits ultrasonic pulses, it cannot simultaneously detect reflected echoes. Due to the time width of the emitted ultrasonic pulses and the residual vibration of the sensor after the ultrasonic waves are emitted, the reflected echoes cannot be detected during this period. Therefore, a small distance from the surface of the probe downwards cannot be detected normally, which is called a blind zone. If the highest level being measured enters the blind zone, the instrument will not be able to detect it correctly, resulting in errors. If necessary, the level gauge can be installed higher.

2. After the equipment installation is completed, it must be truly grounded separately and not grounded with the common ground of the electrical box or instrument box.
3. Suggestion: When connecting ultrasonic level gauges to equipment that interferes with frequency converters, PLCs, etc., isolation transformers should be added to the power supply, signal isolators should be added to the signal section, and reliable grounding treatment should be carried out.
4. The signal line cannot be installed in the same cable tray as the power line or power line. It should be installed separately in a metal tube, or installed away from the power line or power line. Without installation in a tube, the distance from the power line or power line should be at least 1 meter.
