How it calculates the distance
The length of wave travel is converted into a measurement of the level in the tank by our ultrasonic level transmitter. It is attached to the tank’s top and sends an ultrasonic transmitter pulse into the tank.
The liquid surface reflects this pulse to the transmitter as it moves at the speed of sound. The time it takes for the bursts to descend to the reflecting surface and return is measured by our ultrasonic-level transmitter.
This time can be used to calculate the level of fluid in the tank because it is proportional to the distance from the transducer to the surface.
The onboard computer of the ultrasonic transmitter determines the distance to the liquid surface by measuring the lag time between the emitted and received echo signals.
This basic principle lies at the heart of the ultrasonic measurement technology and is determined in the equation Distance = ( Speed of sound in air x time delay) / 2
The transmitter’s microcontroller will calculate the liquid level once it has been configured with the application’s bottom reference, which is typically the bottom of the tank. The fundamental formula for determining the tank’s level is Level = Tank Height – Distance
Elements and Basic Concept of Ultrasonic Level Measurement
Minimum measuring distance (Xm): The “Dead Band” or minimum measuring distance (Xm) is a characteristic shared by all ultrasonic level transmitters. The ultrasonic gadget cannot measure within this small area in front of the sensor.
Maximum measuring distance (XM): The largest area that the transmitter gadget can measure in optimum conditions. Beyond this point, no measurement is feasible.
Our ultrasonic transmitter is a non-contact device available in models that can convert readings into 4–20 mA outputs to DCSs, PLCs, or other remote systems. The frequency range of our ultrasonic level transmitter is 15…200 kHz.
The more challenging applications require lower-frequency instruments. You can use our ultrasonic transmitter for longer distances and solid-level measurements. It is also good for shorter liquid level measurements as well.
Advantages
- Installing ultrasonic transmitters on liquid-filled or empty tanks is simple.
- Set-up is simple, and those devices with onboard programming capability can be configured in minutes.
- As there is no contact with the media and no moving parts, the devices are virtually maintenance-free. Wetted materials are typically made of an inert fluoropolymer and are impervious to corrosion caused by vapour condensation.
- Because the device is non-contacting, the level measurement is unaffected by changes in the liquid density, dielectric, or viscosity, and performs well on aqueous liquids and many chemicals.
- Changes in process temperature will change the speed of the ultrasonic pulse through the space above the liquid, but built-in temperature compensation automatically corrects this.
- Changes in process pressure do not affect the measurement.
