Tips on Ultrasonic Level Gauge Technology

Overview of Ultrasonic Level Gauge

Ultrasonic level gauge (ultrasonic level meter) is a digital level instrument controlled by a microprocessor. In the measurement, the ultrasonic wave is sent by the sensor (transducer), and the sound wave is reflected by the surface of the object and received by the same sensor, which is converted into an electrical signal. The distance between the sensor and the measuring object is calculated from the time between the transmission and reception of the sound wave. Because the ultrasonic level gauge uses a non-contact measurement method, the measuring medium is almost unlimited. It can be widely used for measuring the height of various liquids and solid materials, and it can also be used for ultrasonic transducer 5M distance.PH Series Ultrasonic Level Gauge Ultrasonic Level Sensor) In addition to the intelligent LCD display on the on-site meter head, it also outputs standard analog signals 4-20mA or upper and lower limit alarms (the latest optional RS232 and RS485 digital signal output)

Working principle of ultrasonic level gauge

The ultrasonic sensor transmits and receives ultrasonic waves under the control of a microprocessor, and calculates the distances between the ultrasonic sensor and the measuring object by the propagation time T of the ultrasonic waves in the air. Since the speed C of the sound wave traveling through the air is constant, According to: s = ct / 2, s can be calculated, and because the distance H between the ultrasonic level transducer
and the bottom of the container is constant, the object (liquid) level of the measuring object h = Hs

Technical characteristics

Ultra-low price, high reliability and high precision can completely replace the same imported ultrasonic level gauge. No need for professional technicians, just a little setting can be applied, the instrument of 64KHz ultrasonic transducer is easy to install on site, easy to adjust, and requires less maintenance.
Ultrasonic liquid level meter (ultrasonic level gauge) has automatic power adjustment, gain control, temperature compensation, by using advanced detection technology and calculation technology to improve the measurement accuracy of the instrument, and has the function of suppressing interference echoes to ensure the trueness of the measurement results .

Application fields
Ultrasonic level gauge (ultrasonic level sensor) is an advanced non-contact level measuring instrument, which can completely replace various original other forms of level gauges. It mainly measures liquids such as river water level, waste water level, canned liquid level, mud, oil level, coal pile, ore, etc., and is widely used in sewage treatment, municipal, power plants, chemical plants, steel plants, pharmaceutical plants, wineries. Anticorrosive ultrasonic level gauge is used to measure various acid and salty corrosive liquids.
