Abstract:
A method of determining whether a first or a second type of inline electromagnetic flow probe is inserted into a flow meter comprising the steps of:providing a flow probe having one of a first probe feature characteristic of the first type of flow probe or a second probe feature characteristic of the second type of flow probe; providing a flow meter having means for sensing the first probe feature and the second probe feature, the flow meter outputting a first type of signal upon sensing the first probe feature and a second type of signal upon sensing the second probe feature; inserting a flow probe into the flow meter, the flow probe having one of the first probe feature or the second probe feature; outputting a signal from the flow meter responsive to inserting the flow probe, the signal being one of the first type of signal or the second type of signal, whereby the first type of signal indicates the insertion of the first type of flow probe and the second type of signal indicates the insertion of the second type of flow probe.
