<p>A fluid delivery system (300) comprises a Coriolis mass flowmeter (200), a pump (221), a recirculation valve (222), and/or a back-pressure valve (220). The fluid delivery system prevents the measurement of a multiphase fluid flo w without the need for an air eliminator and strainer. The Coriolis mass flowmeter measures the density value of the fluid product being delivered fr om 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 a nd a lower threshold density value. If the measured density value exceeds the a t least one of the upper density value or the lower density value, the flowmet er 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 t o prevent the measurement of a multiphase fluid flow.</p> |
