System description

The flowmeter consists of a sensor and a transmitter. The sensor is installed in-line with
the process piping; the transmitter can be integrally mounted to the sensor or remotely
mounted away from the sensor.

The flow sensor contains two magnetic coils located on opposite sides of the sensor. Two
electrodes, located perpendicular to the coils and opposite each other, make contact with
the liquid. The transmitter energizes the coils and creates a magnetic field. A conductive
liquid moving through the magnetic field generates an induced voltage at the electrodes.
This voltage is proportional to the flow velocity. The transmitter converts the voltage
detected by the electrodes into a flow reading. A cross-sectional view is show in
