Abstract

The fluid delivery system comprises a Coriolis mass flowmeter, a pump, a recirculation valve, and/or a back-pressure valve. The fluid delivery system prevents the measurement of a multiphase fluid flow without the need for an air eliminator and strainer. The Coriolis mass flowmeter measures the density value of the fluid product being delivered from a fluid source to a destination. The Coriolis mass flowmeter compares the measured density value to at least one of an upper threshold density value and a lower threshold density value. If the measured density value exceeds the at least one of the upper density value or the lower density value, the flowmeter automatically shuts down the pump and closes the back-pressure valve to stop the delivery of the fluid product from the fluid source to the destination to prevent the measurement of a multiphase fluid flow.
