Ultrasonic Level Sensing (ULS) is a low-cost method of measuring liquid levels. Sensors and transmitters for ultrasonic level sensing are used to determine the level of a tank or a canal. Ultrasonic Level Sensing does not require interaction with the medium and can be measured in real time at a low cost. Ultrasonic Level Sensing is therefore very common with consumers. There are two kinds of ultrasonic liquid level sensors: general and internally stable. Output a 420mA standard signal or the measurement result through RS-485 to the secondary meter. Meets the requirements of the system’s automated power.
For constant, non-contact tank level calculation, Sino-Inst provides a range of ultrasonic liquid level sensors and transmitters. Please ask our sales engineers if you have any more queries.

Is it possible to detect water temperatures using ultrasonic sensors?
The Ultrasonic Level Transmitters may be used to determine the level of water in a container. The ultrasonic reflection theory is used in this application. According to the interaction between the pool ultrasonic liquid level gauge’s sound wave and the liquid wall. It represents in accordance with the amount of time. The height of the liquid level in the tank should be measured. Many sites employ liquid level sensors to identify situations that necessitate liquid level control. The liquid level on certain water treatment tanks, the liquid level on the tank, the liquid level on the river path, and so on are all well-known.
What is the principle of use of a capacitive level sensor?
The capacitance adjustment of a capacitor is the foundation of capacitive level calculation. The probe and the tank wall shape a capacitor, and the capacitance of the capacitor is proportional to the volume of product throughout the tank: The capacitance of an empty tank is smaller, whereas the capacitance of a filled tank is stronger. A basic capacitor is made up of two electrode plates divided by a thin layer of insulator, which may be solid, liquid, steam, or vacuum. A dielectric is another name for this kind of insulator. The value of C is determined by the type of dielectric used, the plate area, and the distance between the plates.

Capacitance in picofarads is denoted by C. (pF)
The absolute permittivity of free space is described as E = a constant.
K is the insulating material’s proportional dielectric constant.
A is the conductors’ successful field.
d stands for the difference between the conductors.
An AC bridge can be used to calculate this difference in capacitance.

What is the principle of use of the water level sensor?
Water level devices are used in a variety of configurations. Included are single flange static pressure / double flange differential pressure water level sensors, float type water level sensors, magnetic water level sensors, input type water level sensors, electric inner float water level sensors, electric float level sensors, capacitive water level sensors, magnetostrictive water level sensors, servo water level sensors, ultrasonic water level sensors, and radar water level sensors, among others. It can be separated into two types: touch and non-contact.

What is the working principle of a radar-level transmitter?
Microwaves are transmitted by the radar sensor’s antenna device to the measured product, expressed by the product surface, and obtained by the antenna system in the case of radar level calculation. The time it takes for the messages to be sent and received is equal to the vessel’s volume. The sensor passes microwave signals into the medium from above during continuous non-contact level calculation with radar.
The signals are reflected in the direction of the sensor by the medium’s surface. The sensor measures the distance to the commodity surface and calculates the amount based on the obtained microwave signals. This method of measurement is often used to quantify liquids and solids.
