Non-invasive Ultrasonic Level Sensor Transmitter

Non-contact level measurement, liquid level monitoring with full range, real-time control of automatic production process

The non-invasive Level Transmitter is used to everywhere where the level of liquids in tanks to be measured continuously and without direct contact. Application possibilities for radar gauges can be found in almost all areas of industry. Sewage treatment plants and water purification plants especially, but also other environmental engineering facilities as well as power generating stations now rely on cost-effective radar sensors for continuous level measurement.

Principle

This Non-invasive Level Gauge adopts the principle of Sonar Ranging.
When the probe sensor is bonded to the bottom wall of the tank, a sound wave travels through the tank/medium and reflects back from the liquid surface.
The sensor is responsible for emitting and receiving sound waves, then transmits them to the system, and calculates the height (H) of the liquid, from the time (t) taken for the signal to be received.
Generally, a tank monitoring case often requires two probe sensors at a time:
– The one on the bottom for level measurement, called Measurement Sensor (MEA)
– The other is the Diameter Calibration Sensor(CAL), which bonded on the sidewall, to continuously calibrate the real-time sound velocity and update to the Transmitter.
In some practical applications, the sound velocity would be varied due to environment/liquid temperature change. The accurate sound velocity value would be a key point for the level measurement result.

Application area

For tanks

For spherical, vertical, horizontal and other tanks, a probe installation space of 200mm in length, 200mm in depth and 300mm in height need to be directly below the container.
There is no solid structure (transverse partition, drain plate, column, stirring) between the position directly above the installation position of the measuring probe and the highest liquid level of the liquid.
The thickness of the tank wall at the bottom of the barrier container (where the measuring probe is installed) is ≤100mm. The tank wall at the bottom of the container is made of hard material, such as carbon steel, 16MnR, 304.316, without liner or gas interlayer. Fiberglass, hard rubber, etc.
For medium

The dynamic viscosity of the measured liquid medium is less than 50mPa·s (cP). The liquid has no serious sedimentation, crystallization and self-accumulation. The liquid cannot suspend a large amount of solids and deposit a large amount of sediment. It cannot be an emulsion or cannot have a large number of bubbles. The liquid to be tested is preferably a single liquid or a compatible mixture. If two or a variety of immiscible liquids will form a clear interface, then the instrument must be specially set.

Temperature for probe

Which probe to choose is determined by the temperature of the tank wall (probe measurement position) at the bottom of the container, normal temperature probe is for -196°C ~ 120°C, high temperature probe is for 60°C ~ 200°C
