(11/16). The INVALCO Model 4728 Water Cut Monitor, in conjunction with a Model 4528 Detector and a Model CX-645 Capacitance Probe is a continuous on-line monitor or percent water in a flowing crude oil emulsion stream. This unit displays percent of water in various ranges from 0-5% up to and including 0-20%. on a digital LCD indicator. In addition, the Model 4728 provides a 4-20 mA analog output proportional to input range, and a field-adjusted, time-delayed, limit relay for valve control or alarming. Key Features Real-Time Display and Retransmission of Water Cut Model 4728 Monitor Monitor and Model CX-645 Probe Allows quick response to upset conditions for downstream controls.

The inner (253). tube is insulated from the outer tube by Polytetrafluoroethylene (PTFE) spacers and is electrically connected to a terminal within the sensor housing. The internal element spacers can be fitted (112). with trimmer rods should it be necessary to adjust the base capacitance.. (166) (274). The detector operates from a 12 Vdc regulated power supply NEMA 7 from within the associated monitor or customer supplied Explosion-Proof Housing source. All calibration and adjustments can be accessed through . (258) the front panel for ease of use. The Model 4528 detector offers the flexibility of a high and low fail-safe. This fail-safe feature (222).
