1. How do ultrasonic level sensors work?
An ultrasonic sound pulse is pulsed periodically from the base of the transducer. The pulse travels through air, reflects against the process medium below and returns to the transducer. The sensor measures the pulse time of flight between sound generation and receipt, and translated this into distance or liquid level height within the vessel.
2. What are the advantages of ultrasonic level sensors? Many application liquids have challenging characteristics that negatively impact contact type sensor performance, maintenance and/or replacement costs. Examples include corrosive, coating, scaling, viscous and dirty liquids. Ultrasonic sensors are non-contact, and therefore impervious to these characteristic.
3. What should I avoid with ultrasonic level sensors?
The application variables to avoid with ultrasonic are extreme foam, vapor, turbulence or installation in tall fittings with narrow risers. Foam, vapor and turbulence can absorb and/or deflect away a substantial portion of the return signal. Tall riser fittings can disrupt the acoustic signal path. Appropriate product selection and installation is important.
