PRODUCT OVERVIEW
The ME Transmitter is a two-wire loop-powered flow transmitter, with a 4-to-20mA output. This transmitter uses a non-contact
magnetic encoder for measuring the displacement of the shaft on standard UFM flowmeters: MN/MM/MH and PI model flow
meters as manufactured by Universal Flow Monitors, Inc. The analog output of this device is linear with flow over the working
range of all supported flowmeters.
PRODUCT INTERFACES
PROCESS INTERFACE
MAGNETIC SENSORS
There are two built-in hall-effect sensors measuring the rotation of a permanent magnet that is mounted onto the flowmeter
shaft. As the shaft rotates with flow, the sensors provide analog readings that are in turn converted to a digital value by and A/D
converter. The digital values are then processed by the microcontroller and linearized, and subsequently converted to a scaled
analog output via a D/A converter in the range of 4 to 20 mA.
