Section 1: Introduction System Description The instructions in this manual are for the “AMETEK Drexelbrook - Universal IV CM with Density Compensation Module”. They are supplementary to the Universal IV CM Water Cut Meter instruction manual. The system measures the percentage of water in oil and compensates for changes in oil density using input from a customer supplied density measurement device.
Universal IV™ CM Density Compensated Model Section 2: Installation Mounting the Unit There are 2 electronic units for the Density Compensation Cut Monitor. The DCM is a remote mounted unit. This module has connections for 24 VDC power, a 4 – 20 mA signal loop, Modbus digital output and a relay (SPST). The Cut Monitor Transmitter is either mounted integral to the probe or remote mounted.
Universal IV™ CM Density Compensated Model 2.2.3 Power Wiring to Universal IV CM to the DCM Module The DCM backboard wiring to the CM must go through the bottom of the DCM housing or else the transmitter will not secure properly. Due to the potential for switching interference on the relay it is recommended the relay wires exit the housing via the opposite port of the other wiring entering the housing.
Installation 2.2.4 Universal IV CM Wiring Due to the low power consumption of the instrument, the wiring need only be light gauge (e.g. 20 AWG shielded twisted pair) between the Density Compensation Module and Cut Monitor Module. Remove the DCM electronic unit to access the Customer Wiring Terminal Board. This is accomplished by unscrewing the 2 screws at the 3 o’clock and 9 o’clock positions.

Universal IV™ CM Density Compensated Model 2.2.5.2 (4-20mA) HART 7.0 Signal Loop Wiring Due to the low power consumption of the instrument, the wiring need only be light gauge (e.g. 20 AWG shielded twisted pair) for the 4 – 20 mA signal loop. Shielded twisted pair cables are recommended.
Page 19
Installation 2.2.5.3 Modbus Communications Wiring Due to the low power consumption of the instrument, the wiring need only be light gauge (e.g. 20 AWG) for the Modbus digital output. Shielded twisted pair cable is recommended.
Universal IV™ CM Density Compensated Model 2.2.6 Master & Slave Wiring Configurations 2.2.6.1 Master In the Master configuration the DCM is the Modbus master and requests density, temperature and flow rate data from the connected slave device (Coriolis, PLC, etc.). The corrected Water cut is transmitted to the control system from the DCM via the 4 –...
Installation Initial Start Up 2.3.1 Verify wiring configuration per section 2.2.3 2.3.2 Power up the Cut Monitor (CM) and the Density Compensation Module (DCM) 1. If both units power up properly then skip #2 below 2. If both units fail to power up properly then verify the following voltage levels Minimum voltage at any of these points should be 19VDC.
Universal IV™ CM Density Compensated Model Validate CM Operation 2.4.1 Verify the capacitance values on the CM and DCM match 1. If they do not match, you should see a "HART 5 CRITICAL COMM LOSS FAILURE "on the DCM. To clear this , power cycle the CM only by removing the 4-20mA leads on the CM for 10 seconds then replace them.
Installation 2.5 Modbus Validation Note: There are legacy and current Modbus addressing formats described below. Legacy Modbus Mode While Legacy Modbus Mode is ENABLED, the DCM will automatically use the address offset that corresponds to the function code that is used in the message. See the Latest Modbus Addressing section for additional details.

Installation 2.5 Modbus Validation (Continued) 2.5.1 Establish Modbus communication Note: The Coriolis provides a Density, Temperature and Flow output Insure that your Modbus wires are installed correctly. Using a voltmeter, measure between A & B terminals. Measurement should be approximately +2.5VDC.

If the received data does not match the Coriolis, check your address format! 2.5.4 Verify DCM density value matches Coriolis If Coriolis is set to API and DCM is set to Density –...
Universal IV™ CM Density Compensated Model Section 3: Configuring the Device 3.0 Calibration & Configuration 3.1 Calibration of the Cut Monitor Module Normally the Cut Monitor transmitter will not require calibration. All that is required is it be configured with the correct Water Cut Range. 3.2 Operating the User Interface Configuration and calibration of the DCM is performed via the display keypad or STExplorerTM PC software.
Configuration and Calibration 3.3 Calibration Modes & Field Calibration 3.3.1. Overview There are two different calibration and calculation modes supported by the CM-DC, Two Point and MultiCal calculation modes. Each mode is meant to address the different calibration needs of the various processes throughout the handling of crude oil in the oil and gas industry.

Configuration and Calibration 3.3 Calibration Modes & Field Calibration (continued) 3.3.5. Two Point Calibration Two point calibration mode uses two fixed material calibrations to model the behavior of the process material being measured. Calibration of the DCM while in Two Point calibration mode involves teaching the DCM the electrical properties over a span of process temperature to ensure the proper correction due to temperature affects.

Universal IV™ CM Density Compensated Model 3.3.5.2 Calibration Procedure for Point 2 (continued) 3. Place the oil processing system into ‘Normal Operating Mode’. a. For LACT applications this means actively pumping oil through the wellhead LACT and allowing roughly 1-2 minutes for the system to stabilize and all air/gas to be removed from the system.
