Ultrasonic level gauge It is a device used to measure the surface, with the difference that it does not make contact with the object to measure the surface. In fact, an ultrasonic level gauge uses an ultrasonic or ultrasonic sensor. This type of level gauge measures the desired level by sending sound pulses and receiving the same pulse sent after colliding with the object and determining the speed of the pulse. In cases where it is not possible to make contact with the object or it is not easily possible, ultrasonic level gauges are used. Application of this
ultrasonic level gauge
sensor Suitable for all types of water tanks, paint tanks, sand tanks, milk tanks, any type of tank that contains liquids and paste-like materials or tanks of liquid solids and…. Ultrasonic level gauges can also be used in explosive environments, chemical reservoirs with high corrosion.
How the Ultrasonic Level Meter Works
To measure the height of the surface with ultrasonic level meters, an ultrasonic transmitter and receiver sensor must be installed at the top or where the sensor can be installed at the bottom of the tank, then the device sends an ultrasonic wave into the tank. The travel time of the wave to the surface of the material inside the tank and the return time are measured, and by having the speed of wave movement, the distance from the sensor to the surface of the material and consequently the height of the material inside the tank can be obtained.
The advantage of ultrasonic level gauges
Ultrasonic level gauges have no sensitivity to color, light or odor and can find distance to the target without contact with the object.
• High accuracy and speed
• Automatic calibration and wide temperature range
• No contact with the body and no corrosion and wear
• Low maintenance costs
• Measuring the height of the tanks up to lengths of 15 meters or more
• In addition to sending output current can be output Relay for alarm or control and also RS485 output for sending information through computer
• Reasonable price
Tips to consider when choosing a level meter or ultrasonic level meter:
• Temperature range
• Tank pressure
• Number and type of output Comments
• Environmental conditions
• Measurable height
• Accuracy of equipment
