摘要：
Meter electronics (20) for processing sensor signals for a multi-phase flow material in a flowmeter (5) is provided according to an embodiment of the invention. The meter electronics (20) includes an interface (201) for receiving first and second sensor signals (210 and 211) for the multi-phase flow material and a processing system (203). The processing system (203) is configured to receive the first sensor signal (210) and the second sensor signal (211), generate a first ninety degree phase shift (213) from the first sensor signal (210) and generate a second ninety degree phase shift (214) from the second sensor signal (211), compute a frequency (221) using one of the first ninety degree phase shift (213) or the second ninety degree phase shift (214), compute a phase difference (220) using one or more of the first ninety degree phase shift (213) and the second ninety degree phase shift (214), and compute one or more of a mass flow rate (223), a density (224), or a volume flow rate (225) for the multi-phase flow material.
