Overview
The Universal IV CM is a Water CUt Monitor that is built upon 50 years of applications expertise with RF Admittance. The Universal IV CM has a range of 0-50% in light oil and 0-80% in heavy oil. Our probes can handle pressures up to 1500 PSI and temperatures up to 450°F.

Applications

Automatic Well Testing (AWT)
Lease Automatic Custody Transfer (LACT)
Basic Sediment and Water (BS & W)
Separation Vessels
Pipeline Slug Detection
Truck Unloading
Pump Protection
Dielectric Analysis
Machinery Lube Oil Monitoring
Use the Best
For over 50 years, Drexelbrook has established itself as the world’s leader in capacitive based water cut measurements.

Easy Calibration - Now with Built-in LCD Display and Keypad
All Universal IV CM comes from the factory pre-calibrated and requires only one point validation.

Worldwide Approvals
The Universal IV CM Model has been approved for Class I, Div1, and Zone 0 hazardous locations. FM, FMc, ATEX, as well as IECEx approvals are available.

Durability
Our Perm-A-Seal sensing element does not require epoxy coatings that wear out and require expensive servicing.

Eliminate Routine Maintenance
The Universal IV CM (Cut Monitor) is built upon the Drexelbrook expertise in RF Admittance that allows the electronics to ignore paraffin and other coatings that buildup on the probe.

0-50% in Light Oil & 0-80% in Heavy Oil
The Universal IV CM comes factory pre-calibrated to one of 11 pre-set ranges, for Light Oil (API Gravity > 25) and Heavy Oil (API Gravity < 25)

Cote Shield™
The proven Cote-Shield is designed into the Universal IV CM series and enables the instrument to ignore a pre-determined length of the sensing element.

* 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.
