Universal IV Water Cut Meter (BS&W)With Density Compensation
Analytical Products
The Need For Density Compensation?
The Solution – Drexelbrook Universal IV Cut Monitor (BS&W) with Density Comp• The new Drexelbrook UIV CM utilizes system inputs from the Coriolis/PLC:
Temperature Flow Density
• And calculates the corrected value for true water content and maintains overall system accuracy.
The Problem• The density or API gravity of crude oil changes (temp, material, region or formation)
• Standard cut monitors (BS&W) mistakenly attribute these changes to water content
• It is commonly known that API can vary +10 API in a short amount of time
• Changes as small as 3 API can cause water cut errors of over .45% resulting in false diverts or personnel call outs.

Accuracy and Resolution Water CutRange Variance % wc* Resolution** 0 to 1% +/- 0.03 0.0002 0 to 5% +/- 0.04 0.0009
Load Resistance Maximum 550 ohms at 24 VDC Minimum 250 ohms for HART protocol
Ambient Temperature -40°C to 75°C (-40°F to 167°F)
Process Temperature (Compensated)Up 232°C (450°F) – Transmitter will compensate for the effects of temperature when the water is in liquid state (Eg 0oC to 100oC at ambient pressure)
* The measurement accuracy of an inline, dynamic water cut measurement is dependent upon many process variables including: oil dielectric consistency, fluid velocity at the sample point, mounting geometry and homogeneity of the oil/water emulsion. The values above represent nominal water cut measurement variances for a properly installed sensor under consistent measurement point conditions. ** The smallest water cut step that the instrument can resolve
Process Pressure Up 103 bar (1,500 psi), probe dependent
Density (Compensated)Transmitter will compensate for the effects of changing density in the process flow

Typical Installation of DCM System
Typical Wiring of DCM System
DCM Interface to PLC
• The primary method for retrieving the density data is through the PLC
• This is a Modbus connection between the 2 devices with the DCM configured either as a master or a slave
• The DCM has an Auto-detect feature that insures successful connectivity between the 2 devices
• Installations will require knowledgeable personnel in PLC and Modbus communications
