Many\u00a0petroleum industry flow metering applications feature the use of magnetic-pickup-type turbine meters.\u00a0 (See Figure 1 below.)\u00a0 Internally, these meters feature a steel turbine that rotates past a magnetic pickup, similar in principle\u00a0to\u00a0a string\u00a0pickup in an electric guitar.\u00a0 The signal output from this type of meter is a low-level sine wave, whose frequency and amplitude both\u00a0increase\u00a0as the rate-of-flow increases.<\/p>\n

If data collection of totalization and rate-of-flow\u00a0using an EtherMeter (or another pulse-counting instrument) is desired in\u00a0such a\u00a0situation, then\u00a0the sine-wave signal must be post-processed in order to achieve compatibility with the control\/telemetry\u00a0instrumentation.\u00a0 Fortunately, instrumentation is commercially available that converts the low-level sine wave into a compatible pulse.\u00a0\u00a0One such\u00a0example is the “Mag PreAmp” by Spectec (Emigrant, MT)<\/a>.\u00a0 This instrument is capable of accepting a sine wave directly from the turbine meter, and converting it into an open-collector signal that is compatible with the EtherMeter. (See Figures 2 and 3.)<\/p>\n

In Figure 4 below, a wiring diagram is shown for the integration of a Turbine-Type\u00a0Flow Meter, Spectec PreAmp, and EtherMeter.<\/p>\n

Important Note:<\/strong><\/span>\u00a0 Please ensure that the selected turbine meter does not emit a pulse signal that exceeds\u00a02400 pulses\/second, which is the maximum supported by the EtherMeter.<\/p>\n

Do you have an oil or natural gas flow metering application where you desire the EtherMeter’s ability to gather both totalization and rate-of-flow information from sinusoidal-type meter signals \u2014 and then convert into Modbus and Rockwell automation protocols? If so, give us a call… We’ll be glad to discuss your application in detail.<\/p>\n","protected":false},"excerpt":{"rendered":"
