System for measuring liquid flow through a metering device |
| abstract |
A system is provided that accurately measures the quantity of liquid that is transferred through a flow meter. The system is composed of a flow meter with an ultrasonic fluid (liquid) sensor mounted therein that operates to sense the presence or absence of liquid flowing through the flow meter so that air flow is not erronecously measured as liquid flow. When there is substantially no liquid flow through the meter, the ultrasonic fluid (liquid) sensor interrupts the transmission of an output signal from a signal-conditioning circuit to a totalizer that operates to process the signal and total the amount of liquid so that any non-liquid material passing through the meter is not included in the total amount of removed liquid by the totalizer. Also provided are methods of using the system to accurately measure the amount of liquid flowing through a flow meter, such as in a grease trap pumping operation. |
