LOAD LEVELING BOOST SUPPLY FOR MAGNETIC FLOWMETER

LOAD LEVELING BOOST SUPPLY FOR MAGNETIC FLOWMETER

A magnetic flowmeter for measuring a fluid flow includes a flow tube assembly receiving the flow and having a coil with first and second coil wires for receiving a coil current and responsively producing a magnetic field thereby generating an EMF in the fluid representative of a flow rate. An EMF se...

description A magnetic flowmeter for measuring a fluid flow includes a flow tube assembly receiving the flow and having a coil with first and second coil wires for receiving a coil current and responsively producing a magnetic field thereby generating an EMF in the fluid representative of a flow rate. An EMF sensor is arranged to sense the EMF and generate an output indicating the flow rate. Current supply circuitry applies a current supply signal to the coil. A load leveling boost supply provides power to the current supply circuitry. In another aspect, power scavenging circuitry recovers power from the coil.
