INTRODUCTION TO HART ®FIELD DEVICE SPECIFICATIONS
Scope
The Universal Flow Monitors water flow transmitter, model ME Transmitter complies with HART Protocol Revision 7.0. This
document specifies all the device specific features and documents HART Protocol implementation details (e.g., the Engineering
Unit Codes supported). The functionality of this Field Device is described sufficiently to allow its proper application in a process
and its complete support in HART capable Host Applications.
PURPOSE
This specification is designed to complement other documentation (e.g., the installation manuals specific to PI, MN/MM/MH/
model flow meters) by providing a complete, unambiguous description of this Field Device from a HART Communication
perspective
WHO SHOULD USE THIS DOCUMENT?
The specification is designed to be a technical reference for HART capable Host Application Developers, System Integrators and
knowledgeable End Users. It also provides functional specifications (e.g., commands, enumerations and performance
requirements) used during Field Device development, maintenance and testing. This document assumes the reader is familiar
with HART Protocol requirements and terminology.

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.

EX-MANUAL-032321 13
HOST INTERFACE
ANALOG OUTPUT 1: PROCESS FLOW
The two-wire 4-20mA current loop is connected to two terminals on the transmitter circuit board. Depending on the product
used, one of the two configurations are offered for field wiring.
A secondary terminal strip away from the PCB (mounted in a separate compartment of the flowmeter) and is marked (+) and (–).
The red wire connects the (+) terminal on the PCB to (+) and the black wire connects the (–) terminal on the PCB to (–).

EX-MANUAL-032321 14
Load Resistor vs. Power Supply
This is the only output from this transmitter, representing the process flow measurement, linearized and scaled according to the
configured range of the instrument. This output corresponds to the Primary Variable. HART Communication is supported on this
loop.
A guaranteed linear over-range is provided. Device malfunction can be indicated by the up-scale current of 24mA. Current
values are shown in the table below.

The PV is derived using a calibrated linearization table applied to A/D converter readings of hall-effect sensors.
The SV is based on a 5ms timer and is updated based on the current reading of flow.
Both PV and SV values are smoothed.
