Tunable empty pipe function

An electromagnetic flowmeter assembly for measuring a flow rate of a fluid in a pipe, the flowmeter assembly comprising:

• a magnetic flowmeter coupled to the pipe containing the fluid, the flowmeter comprising magnetic coils disposed on opposing sides of the pipe to generate a magnetic field substantially perpendicular to a direction of fluid flow and a plurality of electrodes disposed on opposing sides of the pipe and extending into the fluid flow, each of the plurality of electrodes being electrically isolated from one another;
• and
• measurement circuitry coupled to at least one of the plurality of electrodes and adapted to measure a flow rate as a function of a potential across the plurality of electrodes;
• and
• an empty pipe detector coupled to the measurement circuitry and adapted to detect an empty pipe condition based upon an adjustable test criteria.

A magnetic flowmeter assembly comprising:

• a magnetic flowmeter adapted to induce a voltage within a fluid flowing within a pipe with a magnetic field and to measure a flow rate of the fluid based on the induced voltage potential between electrodes disposed within the pipe;
• an empty pipe detector coupled to the flowmeter and adapted to detect empty pipe conditions based on the induced voltage potential and one or more adjustable test criteria;
• and
• an adjustment interface coupled to the empty pipe detector for adjusting the one or more adjustable test criteria based on measurement data of an empty pipe condition.
