Ultrasonic

Continuous level measurement is a very important process variable either for control, inventory or safety applications is vital information needed for your plant operation.

There are two main types of products to measure level liquids or bulks, with many different characteristics, water base, hydrocarbons, chemicals, powders, granulates, with foam presence, turbulence surface or dusty atmosphere so the selection of the correct level measurement instrument need the assistance of an expert to get the best result for your process.


Ultrasonic

Measurement Principle

It is based on the principle of time of flight. A sensor emits ultrasonic pulses, the surface of the product reflects them, providing a signal and the sensor detects it. The return time of the reflected ultrasonic signal is directly proportional to the distance traveled. This allows the level to be calculated knowing the geometric shape of the tank.

ADVANTAGE

Applicable for the measurement of liquids and solids. Insensitive to product properties

Non-contact measurement that does not require maintenance. Easy installation and commissioning.

Measurement accuracy ± 2mm + 0.17% of the measured distance

Temperature: -40 to +80 ° C or +150 ° C (-40 to +176 ° F or +302 ° F), Pressure: +0.7 to +1.5 bar (+10 to +22 psi) Range Maximum measurement for solids: 45 m (148 Ft)

Self-cleaning effect thanks to the vibrating diaphragm of the sensor.
