2.2. Introduction to HART® Field Device Specifications
2.2.1. 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.

2.2.2.

Purpose
This specification is designed to complement other documentation (e.g., the installation manuals specific to PI, LL, LP, LH, SN, SM, SH, MN, MM, MH, SX, MX, LN, LE, and XHF model flow meters) by providing a complete, unambiguous description of this Field Device from a HART Communication perspective.

2.2.3.

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.

2.3. Process Interface
2.3.1. 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.

2.3.2.

Host Interface Analog Output 1: Process Flow
The two-wire 4 to 20 mA 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.
The first option allows the user to directly connect the loop wires to the terminals on the PCB. The correct polarity is shown in the pictures below, where the red wire is connected to the (+) terminal and the black wire is connected to the (­) terminal.

4.1. Installation
For best results, the meters may be installed in any position as long as proper piping installation requirements are observed. This includes sufficient support of adjacent piping to minimize the system’s inherent vibration. Unions of the same pipe size and full port isolation ball valves may be installed for ease of removal and servicing of equipment, if necessary.

4.4. Product Overview
The ME Transmitter is a two-wire loop-powered flow transmitter, with a 4 to 20 mA output. This transmitter uses a non-contact magnetic encoder for measuring the displacement of the shaft/pointer on standard UFM flowmeters. It is an add-on feature to PI, LL, LP, LH, SN, SM, SH, MN, MM, MH, SX, MX, LN, LE and XHF model flow meters as manufactured by Universal Flow Monitors, Inc. The ME Transmitter replaces the earlier models Digital Transmitters that utilized a potentiometer, providing improved accuracy while maintaining 100% compatibility. The analog output of this device is linear with flow over the working range of all supported flowmeters.

4.5. Process Interface
4.5.1. 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.

4.5.2.

Host Interface: Process Flow
The two-wire 4 to 20 mA 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.

There is a secondary terminal strip away from the PCB (mounted in a separate compartment of the flowmeter) and is marked L+ and L-. The red wire connects the (+) terminal on the PCB to L+, and the black wire connects the (­) terminal on the PCB to L-.

Figure 12: PCB wiring
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.

5.1. Installation
For best results, the meters may be installed in any position as long as proper piping installation requirements are observed. This includes sufficient support of adjacent piping to minimize the system’s inherent vibration. Unions of the same pipe size and full port isolation ball valves may be installed for ease of removal and servicing of equipment, if necessary.

5.3. Product Overview
The ME Transmitter is a two-wire loop-powered flow transmitter, with a 4 to 20 mA output. This transmitter uses a non-contact magnetic encoder for measuring the displacement of the shaft/pointer on standard UFM flowmeters. It is an add-on feature to PI, LL, LP, LH, SN, SM, SH, MN, MM, MH, SX, MX, LN, LE and XHF model flow meters as manufactured by Universal Flow Monitors, Inc. The ME Transmitter replaces the earlier models Digital Transmitters that utilized a potentiometer, providing improved accuracy while maintaining 100% compatibility. The analog output of this device is linear with flow over the working range of all supported flowmeters.

UFM Vane Piston Consolidated Manual

5.4. Process Interface
5.4.1. 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.

5.4.2.

Host Interface: Process Flow
The two-wire 4 to 20 mA 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 L+ and L-. The red wire connects the (+) terminal on the PCB to L+, and the black wire connects the (­) terminal on the PCB to L-.

Figure 19: PCB wiring
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. The up-scale current of 24 mA can indicate device malfunction. Current values are shown in the table below.

1. After the last digit is set, continue holding A2 until “SEt” is displayed. If you want to change the first digit again, do not hold A2. Momentarily press and release A2 and the first digit starts blinking again.
2. When finished recording the new setpoint (“SEt” is displayed), release A2.

Figure 23: Press and release A2
Note: Valid setpoint range is 0-100% of full-scale flow. If the alarm value is set higher than full-scale, it is clamped at full-scale upon exiting this menu.
To disable the alarm, set its value to zero.
The red ALARM 1 LED comes on when flow exceeds this setpoint. This LED is in series with the drive circuit for the high-alarm open-collector output, meaning that the output transistor is active whenever this LED is on. Some models do not have any external wiring that connects to the alarm transistor (see Model Codes).
In this example, the high alarm had been set for 80.0; therefore, the red LED was activated when flow reached 80.1. The LED turns off when flow < (setpoint ­ hysteresis). Hysteresis is 5% of full-scale.
