The INVALCO Model 4528 EZ Detector Card is a micro processor based instrument. When used with an INVALCO Model CX-645 Capacitance Probe it is a continuous on line monitor and alarm of the percent BS&W in a flowing crude oil emulsion stream. When used in conjunction with an INVALCO Model 4728 BS&W Monitor, the user can obtain a real time visual indication of percent BS&W in a flowing crude oil stream.
Features
-
Field Selectable 0-5, 0-10, 0-20% BS&W detection range.
-
Button entry of cut, calibration, automatic span calibration, compensated for Dk.
-
Continuous detection and automatic indication of probe faults, and readings outside the calibrated range switchable fail-safe high or low.
-
A single red LED used to indicate various modes of operation.
