Abstract: A flowmeter includes a process sensor assembly providing a sensor signal and a filter stage comprising a low pass filter and a high pass filter and providing a filtered signal from the sensor signal. A processor determines that a filtered signal is indicative of a low flow condition for a first fluid, alters at least one parameter of the low pass filter and at least one parameter of the high pass filter in response to the low flow condition such that the filter stage provides a new filtered signal, determines that the new filtered signal is not indicative of a low flow condition for a second fluid and generates an alarm in response to the new filtered signal not being indicative of a low flow condition for the second fluid.

Abstract: An industrial process control field device includes a process variable transducer configured to sense or control a process variable. Field device circuitry is configured to couple to the process variable transducer and communicate information related to the process variable to another location. The field device circuitry includes an optical isolator having transmit circuitry on a first side of a galvanic isolation configured to transmit an optical signal which is pulsed on and off across the isolation. Receive circuitry is located on a second side of galvanic isolation and configured to receive the optical signal with an optical sensor. The optical sensor enters an “on” state when it receives a pulse and is otherwise in an “off” state. The receive circuitry provides a secondary side output based upon the received optical signal. The receive circuitry enters in a low power state when the optical sensor is in the “off” state.

Abstract: A magnetic flowmeter includes a flowtube arranged to receive a flow of process fluid. A coil is positioned proximate the flowtube and arranged to apply a magnetic field to the process fluid in response to a drive current alternating direction. First and second electrodes are arranged to sense a voltage potential in the process fluid in response to the applied magnetic field. The voltage potential is indicative of flow rate of process fluid through the flowtube. A sensor is coupled to the first and second current paths which has a sensor output related to the drive current. Diagnostic circuitry provides a diagnostic output as a function of a transient change in the sensor output when current flowing through the coil alternates direction.
