Section 1: Introduction
1.1 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.
Each AMETEK Drexelbrook Universal IV CM-DO system consists of a
1. Density Compensation Module (DCM)
- Power - four-wire
- HART 7.0 4-20 mA
- Modbus
2. UIV CM Water Cut Meter RF Admittance transmitter
-with a 700 series sensing element
3. Customer Supplied Coriolis meter or other device providing density, temperature
and ow rate outputs via ModBus
Capacitance is supplied to the DCM from a UIV CM via HART 5.0.
1.2 Unpacking
Carefully remove the contents of the carton and check each item against the packing
list before destroying any packing material. If there is any shortage or damage,
report it immediately to the factory.

Section 2: Installation
2.1 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. This unit is connected to the probe and power is provided by the Density
Compensation Module. For remote mounting greater than 100 ft. consult factory.
Reference the Universal IV Cut Monitor manual for mounting of this module
Remote electronic units are designed for eld mounting, but should be mounted in a
location as free as possible from vibration, corrosive atmospheres, and any possibility of
mechanical damage. For convenience at start-up, mount the instrument in a reasonably
accessible location. Ambient temperatures should be between -40°F and 167°F (-40°C
and 75°C)

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.
If trying to communicate via HART on the 4-20mA Loop, you must have a 250Ω resistor in series with the Loop.
Reference Appendix A for information on the
Modbus terminating resistor

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. The
captive screws can then be used to lift the electronics from the housing.
2.2.5 Density Compensation Module Wiring
The signal connections are made to the terminal block on the front of the Density
Compensation Module chassis.
2.2.5.1 Power Wiring
Due to the low power consumption of the instrument,
the wiring need only be light gauge (e.g. 20 AWG).
Shielded twisted pair cables are recommended
Supply Voltage requirement is 19-30VDC.
*Shield wire may be “Grounded” at the identied
housing screw or cut depending on the power
conguration. Ground

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. Supply Voltage requirement is 19-30VDC. Minimum loop
resistance for HART® communications is 250 Ω. Minimum 19V @ 22mA is required
at the 4-20mA input terminals.

the power conguration

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.

2.2.6 Master & Slave Wiring Congurations
2.2.6.1 Master
In the Master conguration the DCM is the Modbus master and requests density,
temperature and ow 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 – 20 mA loop and all other parameters via HART.
2.2.6.2 Slave
In the Slave conguration the external Modbus master, typically a PLC, is writing
density, temperature and ow data to the DCM slave. The corrected Water cut is
transmitted back to the control system from the DCM via the 4 – 20 mA loop and all
other parameters via HART.
2.2.7 SPST Relay Wiring
Selection of the wire size should be based on the power that will be switched.
Due to the potential for switching interference on the relay it is recommended the relay
wires exit the housing via the left port and all other wiring exit the housing via the right
port.
