A level gauge that can issue an alarm when foam is generated at the liquid level – what type of level gauge can achieve this?
Thread Content
I would like to know if there are any products for measuring liquid levels that can provide an alarm when foam is generated in the medium, or when a certain level is reached; I’m hoping to find successful products of this kind
E+H’s radar and ultrasonic level gauges have a function that triggers an alarm when foam is detected. As for your second question, you didn’t explain it very clearly; my understanding is that an alarm is generated when the liquid level reaches a certain value. This function can be implemented using a DCS, while if it is to be implemented on-site, then instruments equipped with relay-based alarm functions will be necessary
Basically, radars cannot detect foam; therefore, this feature can be utilized for this purpose. In normal situations, the liquid level can be measured, but when there is foam present, the radar loses signal and is unable to take accurate readings, at which point an alarm is triggered. It’s important to note that the alarm is triggered not because foam has been detected, but rather because the foam prevents the radar from measuring the liquid level. The radar then issues a fault alert, yet this still achieves the desired goal
Teacher Pig has a point too! The idea is great, but reality is harsh! Looking forward to researching whether there are instruments that can measure foam :)
How is foam detected? It’s a technical challenge. .
Does the original poster have a soy milk maker at home? The foam generated when making soy milk is detected using electrical contacts.
